Um dos mais intrigantes, complexos e controversos desafios da Odontologia Legal é o reconhecimento, registro e análise de marcas de mordidas na pele. Este estudo teve como objetivos: abordar os aspectos relevantes sobre a importância do estudo das marcas de mordidas; produzir informações sobre a ocorrência de casos registrados no Instituto Médico Legal da cidade de Araçatuba-SP, nos últimos cinco anos, envolvendo lesões ocasionadas por mordidas humanas; avaliar comparativamente quatro materiais de moldagem para estudo de marcas de mordidas na pele e testar a aplicabilidade da técnica proposta, por meio de um caso simulado. Foram analisadas 7.550 ocorrências policiais do período de 2001 a 2005. Verificou-se: idade das vítimas, parentesco com o agressor e ocorrência de lesões produzidas por mordidas humanas, bem como, o local mais acometido por tal ferimento. Nas etapas laboratoriais foram utilizados cinco suínos abatidos, com idade média de oito semanas e pesando cerca de seis quilos. Eles foram divididos ao meio e, em seguida, entre dez voluntários foi feito um sorteio sendo que quatro sorteados morderam cada uma das partes, sem conhecimento do pesquisador. A análise das mordidas foi feita de acordo com as normas da ABFO. Foram utilizados os materiais de moldagem: Alginato, Poliéter, Silicone de Condensação e Silicone de Adição. Durante o estudo de caso, a partir dos modelos de gesso e das partes mordidas, foi feita a identificação dos agentes das mordidas, utilizando a técnica da Análise Métrica, e, como controle, a técnica de sobreposições de imagens com uso do Software Adobe Photoshop 7.0. Foram encontrados quarenta e dois casos envolvendo, dentre outros tipos de lesões, as marcas de mordidas. O total de lesões encontradas foi de cinqüenta e seis mordidas: trinta e três pessoas foram vítimas (31 do sexo feminino e 11 do sexo masculino) e oito foram os autores das agressões (todos homens).
One of the most intriguing, complex and controversial challenges of the Legal Odontology is the recognition, registers and analysis of bite mark. This study objectives was: observe the relevant aspects about bite marks analyses importance, using a literature review; demonstrate the prevalence of bite marks in domestic violence crimes involving physical aggression with were collected data in the Police Station of the Woman's Defense in Araçatuba (São Paulo/Brazil); evaluate comparatively four impressions materials for bite marks analysis on skin and test the proposed technique applicability, with a simulated case. 7.550 occurrences policemen of the period from 2001 to 2005 were analyzed. It was verified: the victims' age, relationship with the aggressor and occurrence of lesions produced for bitten human, as well as, the place more attacked by such wound. In the laboratorial phase, it was used five pigs, with eight weeks ages. They were cute, soon afterwards, among ten volunteers it was made a draw and four raffled they bit each one of the parts, without the researcher's knowledge. The analysis of the bites was made in agreement with the norms of ABFO. The molding materials were used: Alginate, Poliéter, Condensation Silicon and Addition Silicon. During the case study, starting from the models of plaster and of the bitten foods, it was made the agents' of the bites identification, using the technique of the Metric Analysis, and, as control, the technique to put upon of images with use of the Software Adobe Photoshop 7.0. They were found forty two cases involving, among other types of lesions, the marks of bitten. The total of found lesions was of fifty six bitten: thirty three people were victims (31 female and 11 male) and eight were the authors of the aggressions (all men).

Resumo: O esmalte dental é caracterizado por camadas de prismas em direções alternadas regularmente. Estas camadas sucessivas formam as Bandas de Hunter-Schreger (HSB) que aparecem como faixas claras e escuras quando vistas sob forte iluminação lateral. Neste presente trabalho avaliamos a singularidade das HSB em dentes humanos como um método biométrico para identificação pessoal, já que as diferenças no padrão das HSB em dentes ainda não foi estudada. A amostra foi composta de 274 incisivos inferiores. Os procedimentos seguintes foram executados: os dentes foram fotografados em uma lupa esteroscópica e fibra óptica acopladas. O contraste das imagens após digitalização, foi aumentado utilizando Corel Photo Paint 9® e então as mesmas imagens foram analisadas em software de identificação automatizado de base biométrica (Verifinger 4.2 SDK / Fingersec®). O software gerou uma lista de comparações de dados biométricos com uma medida de semelhança (comparações entre ¿minutias¿). As medidas de similaridade do banco de dados foram comparadas em uma matriz de semelhança. Analisamos também a variação das espessuras médias das Bandas desde que este parâmetro é muito variável e pode ser usado para confirmar a identificação. Os resultados demonstraram que o padrão de HSB é altamente variável e único para cada dente analisado. HSB não puderam ser observadas em 4,5% dos dentes examinados. Dentes sem HSB não foram incluídos no banco de dados. Dentes com 0 ou 1 minutias totalizaram 3,3% da amostra. Nestes casos, a distinção pode ser feita através de comparação visual simples. Assim, as medidas biométricas das HSB provaram ser um método com alta potencialidade para identificação pessoal, desde que o tecido do esmalte resiste condições ambientais extremas e as imagens são obtidas facilmente. Estas características fazem das HSB um modelo potencialmente útil para análise forense utilizando medidas físicas ou biológicas pessoais, dando uma descrição correta do indivíduo
Abstract: Dental enamel is characterized by layers of prisms with regularly alternating directions. These successive layers form Hunter-Schreger Bands (HSB) that appear as dark and light bands when viewed under strong illumination. In the present study, we evaluate the HSB singularity in human teeth as a biometric-based method for personal identification since differences in HSB patterns have never been studied. The sample was composed of 274 lower incisors. The following procedures were performed: the teeth were photographed at low magnification, the contrast of the captured images was increased using Corel Photo Paint 9® and then analyzed in automated biometrics-based identification software (Verifinger Demo 4.2 SDK / Fingersec®). The software generated a list of biometric data comparisons with a similarity measure (minutiae matching). The storage of database comparisons could be represented with a similarity matrix. We also analyzed the thickness of the bands since this parameter is very variable and could be used for the identification. The results demonstrated that the pattern of HSB is highly variable and unique for each tooth. HSB bands could not be observed in 4.5 % of the teeth examined. Teeth without HSB could not be included in the database. Teeth having 0 or 1 minutiae comprised 3.3% of our sample. In these cases, the inspection was simply done by visual comparison. Thus, the biometric measurements of HSB proved to be a valuable method for personal identification, since enamel can resist extreme environmental conditions and the images could be easily obtained. These characteristics make HSB a potentially useful model for personal physical or biological measurements to give a correct description of an individual

Resumo: Introdução: As radiografias carpais e panorâmicas de crianças e adolescentes são importantes em identificação humana por serem simples de obter e por conterem quantidade significativa de estruturas que trazem informações relevantes sobre o desenvolvimento corporal. Muitas vezes é necessário estimar a idade pelo envolvimento dessas crianças em procedimentos cíveis e criminais. Várias técnicas existentes usam as informações destas radiografias mas, nem todas foram testadas em brasileiros. Objetivo: Este trabalho procurou validar em uma população brasileira três métodos que estimam a idade de crianças e adolescentes a partir de medidas nos dentes permanentes em desenvolvimento e nos ossos da região do carpo e compará-las. Material e método: Esse estudo usou radiografias de 234 crianças e adolescentes (126 meninas e 108 meninos) para validar o método numa população brasileira. Os dados obtidos a partir das radiografias foram inseridos nas fórmulas propostas e comparados com a idade conhecida de cada sujeito da pesquisa. A precisão dos métodos em estimar a idade foi analisada através do teste de regressão linear estatística (ANOVA). Resultados: A partir da comparação entre as três técnicas estudadas, foi encontrado um erro médio para a técnica da região dos dentes (RD) de -0,21 anos, sendo -0,14 anos para meninas e -0,28 anos para os meninos havendo tendência, então, de subestimar a idade. Para a técnica da região do carpo (RC) o erro médio encontrado foi 1,61 anos, sendo 1,89 anos para meninas e 1,29 anos para os meninos, superestimando a idade. Quando foram utilizadas informações dos ossos do carpo e dos dentes (RCD) simultaneamente, o erro médio encontrado foi 0,39 anos, sendo 0,54 anos para meninas e 0,21 anos para meninos, havendo uma tendência a superestimar a idade cronológica das crianças. Conclusão: As técnicas RD e RCD possuem boa acurácia para estimativa da idade numa população do sudeste do Brasil. O método mais preciso foi o RD, seguido pelo RCD e pelo RC
Abstract: Introduction: Hand-wrist and panoramic radiographs of children and adolescents are important in human identification because they are easily obtained and contain a significant amount of structures that provide important information about the body¿s development. It is often necessary to estimate the age of children involved in civil and criminal proceedings. Many methods use the information in these radiographs, but not all of them have been tested in Brazilians. Objective: This study attempted to validate, in a Brazilian population sample, three methods that estimate the ages of children and adolescents using measurements of developing permanent teeth and wrist bones, and to compare the methods. Materials and methods: This study used the radiographs of 234 children and adolescents (126 girls and 108 boys) to validate the methods in a Brazilian population sample. Age was estimated using radiographic data and the pertinent formulas, and compared with the known chronological age of each study subject. The methods¿ accuracy for estimating age was determined by analysis of variance (ANOVA). Results: The mean error for the tooth region method (TR) was -0.21 years, -0.14 for girls and -0.28 for boys; therefore, this method underestimated chronological age. The mean error for the hand-wrist region method (HWR) was 1.61 years, 1.89 for girls and 1.29 for boys; hence, this method overestimated chronological age. When the two methods were used simultaneously (HWTR), the mean error was 0.39 years, 0.54 for girls and 0.21 for boys; thus, both methods combined overestimated chronological age. Conclusion: The TR and HWTR methods can estimate the chronological age of a population sample from Southeast Brazil with good accuracy. The most accurate method was TR, followed by HWTR and HWR

Resumo: O objetivo deste trabalho foi realizar a análise retrospectiva dos casos investigados nos dois primeiros anos de funcionamento do Serviço de Antropologia Forense (SAFO) do Rio de Janeiro. Foram recebidas 66 requisições de exames expedidas por autoridades policiais ou judiciárias e cada requisição deu origem a um laudo. Seis requisições continham ossos de origem não humana, três representavam materiais sem interesse forense, enquanto uma outra requisição solicitava exame complementar. As demais 56 requisições continham ossos de 74 diferentes indivíduos, pois nove requisições encaminhavam ossos de mais de uma pessoa. Cinco das 74 ossadas não deram entrada no laboratório do SAFO por terem sido identificados pelo Serviço de Odontologia Forense ou pelo Setor de Necropapiloscopia. Logo, 69 ossadas foram periciadas e o resultados desses exames compõe o presente estudo. Dentre as 56 requisições, 47 (83%) eram constituídas de remanescentes de um único indivíduo, enquanto 9 (17%) traziam ossos de mais de uma pessoa. Menos de 18,8% das 69 ossadas tiveram mais de 95% dos ossos do corpo recuperados, enquanto que apenas 10,14% das 47 ossadas encontradas completamente esqueletizadas tiveram mais de 50% dos seus ossos recuperados. O perfil biológico resultante dos exames das ossadas revelou que a amostra era predominantemente constituída por homens (80%), caucasoides (32%), adultos-jovens entre 21-50 anos (54%) constituindo o grupo de risco. O trauma mais frequentemente observado foi o contundente, correspondendo a 33,3% dos casos, seguido do perfurocontundente, observado em 31,4%. A região mais atingida foi a crânio-cervical, atingida em 42% dos traumas. A relação mais alta observada entre um tipo de trauma e uma região específica do corpo foi a ação perfurocontundente incidindo sobre a região crânio-cervical, correspondendo à 27,3%. 52,1% das ações perfurocontundentes foram observadas na região crânio-cervical. Por fim, a analise dos locais de encontro de ossadas evidenciou um grande número de encontro reduzido a poucas áreas da cidade, revelando que existe concentração da violência
Abstract: The aim of this study was to perform a retrospective analysis of the cases investigated in the first two years of the Forensic Anthropology Service (SAFO) of Rio de Janeiro. Over these two years the laboratory received 66 examination requisitions requested by police or judicial authorities and each of these requests has resulted in a report. Six corresponded to non-human material, other 3 represented material without forensic implications and another one corresponded to a complementary examination requisition. The remaining 56 requisitions comprised a total of 74 different individuals, once there were 9 cases with bones of more than one person. Five out of 74 skeletal remains did not enter the SAFO laboratory because they had been positively identified by the Forensic Dentistry Office or through Necropapiloscopy. Therefore 69 skeletal remains were examined and the resulting data compose the present study. Out of 56 requisitions, 47 (83%) presented skeletal remains of single individuals; whereas the other 9 (17%) conteined bones of more than one individual. Less than 18.8% of 69 skeletal remains recovered comprised more than 95% of body bones, wile only 10.14% of the 47 fully skeletonized remains had more than half of the bones recovered. The biological profile established after skeletal remains were investigated showed that the sample was made up mainly of male subjects (80%), caucasian (32%), young-adults ranging from ages 21-50 (54%), considered as the risk group. Injuries most frequently observed were blunt trauma (33.3%), followed by gunshot (31.4%). The most susceptible body regions were the head and neck, affected in 42% of cases. The highest correlation between type of trauma to a specific body part was observed with gunshot injuries to the head-neck region, corresponding to 27.3% of the cases. Gunshot trauma represented 52.1% of injuries found on the head and neck. Analysis of the places where the remains were recovered reveled a great number of cases restricted to a few areas of the city, which shows the violence is concentrated in these localities

Full textResumo: A Reconstrução Facial Forense (RFF) é uma técnica das Ciências Forenses que possibilita o reconhecimento de um indivíduo, a partir da modelagem dos contornos dos tecidos faciais sobre um crânio encontrado sem identificação. Para isto é necessário ter o conhecimento da espessura dos tecidos moles faciais (ETMFs) que recobrem os pontos craniométricos no crânio subjacente, pois os mesmos são utilizados como base para a obtenção do contorno facial. Fatores como sexo, ancestralidade, idade, e índice de massa corporal (IMC) influenciam tais espessuras. O objetivo deste estudo foi mensurar ETMFs de sujeitos brasileiros adultos vivos, a partir de imagens de tomografia computadorizada de feixe cônico (TCFC), considerando-se as variáveis sexo, cor de pele, idade e índice de massa corporal. Foram efetuadas mensurações de 21 pontos craniométricos de referência através do uso do software Osirix Lite. Um total de 92 imagens foram analisadas (62 de sujeitos do sexo feminino e 30 do sexo masculino). Os resultados obtidos mostraram que os homens, na maioria das vezes, apresentaram espessuras de tecidos moles faciais maiores do que as mulheres. Em relação às outras variáveis, houve interação com o sexo a cor de pele nos pontos glabela, nasion, infradentale, eminência frontal, supraorbital e linha oclusal, mas nos pontos eminência mentoniana e suborbital a significância foi correspondente à cor da pele.

Abstract: Forensic Facial Reconstruction (FFR) is a Forensic Science technique that enables the recognition of an individual, from modeling the contours of facial tissues on a skull found without identification. For this, it is necessary to know the thickness of the facial soft tissue that covers the craniometric points in the underlying skull, since they are used as the basis for obtaining the facial contour. Factors such as sex, ancestry, age, and body mass index (BMI) influence such thicknesses. The objective of this study was to measure the facial soft tissue thickness (FSTT) of living adult Brazilian subjects using cone beam computed tomography (CBCT) images, considering the variables sex, skin color, age and body mass index. Twenty-one reference craniometric points were measured using the Osirix Lite software. A total of 92 images were analyzed (62 females and 30 males). The results showed that men, for the most part, had greater facial soft tissue thicknesses than women. In relation to the other variables, there was interaction with the skin color at the glabella, nasion, infradentale, frontal eminence, supraorbital and occlusal lines, but at the eminence points of the chin and suborbital the significance was corresponding to the color of the skin. The BMI did not show interaction with the sex, however, in the medium and supradentale filter points, the men presented higher values of thickness, independently of the BMI. At the remaining points, only BMI influenced the thickness o... (Complete abstract click electronic access below)

Resumo: Alguns fatores relacionados ao estado e lugares que dentes humanos se encontram, nos que diz respeito a estes enquanto amostras com finalidade forense, ainda constituem desafio ao que tange o uso dos mesmos como material para obtenção de perfis genéticos de DNA. Este estudo visou comparar a extração de DNA feita a partir de dentes humanos com a extração por meios de amostras de sangue fixadas em papel FTA® utilizadas como grupo controle, de maneira a comparar os alelos mapeados e definir se os dentes constituem nestas circunstâncias, fonte viável de amostras para obtenção de perfis genéticos, comparando os protocolos. Dezoito participantes foram abordados e, aceitaram participar da pesquisa por meio de TCLE's, doaram voluntariamente amostras de sangue e os elementos dentários terceiros molares superiores direitos, estes indicados para exodontia por outros profissionais. Verificou-se que os dentes humanos constituíram fontes viáveis de acordo com a análise estatística realizada (Teste de Poisson), onde p<0,0001, entretanto quando comparado com o protocolo de extração de material genético através do sangue, deixa de ser viável devido ao número de passos necessários para a obtenção dos resultados.

Abstract: Several factors related to how and where human teeth are found in forensic cases still a challenge to obtain genetic DNA profiles, as using theses elements as source for genetic material. This study aimed to compare the DNA extraction done through blood stains in FTA® paper cards, used as control group, and compare the mapped alleles from these to ones extracted from human teeth samples, as the simplicity of theses protocols when in comparison. Eighteen participants were convinced to join this study. Blood samples and superior right third molars (element 18) were donated. As result, teeth provided good sources of biologic sampling to obtain genetic profiles when analyzed by Poisson statistic analysis (p<0,0001), however, when compared to genetic material extraction protocol by blood, teeth analysis is no longer viable due to extensive laboratorial steps in order to gain the same results. Also 78,125% of the possible locci to be mapped and amplified were indeed

Resumo: Os traços não-métricos na morfologia dental, por sua excelente preservação, e variação inter-populacional livre de pressão seletiva, são reconhecidamente um dos principais focos de observação para os pesquisadores que analisam variação humana e sua relação com o histórico biológico das populações. Considerando sua utilização em contexto forense, o conhecimento das características morfológicas do arco dental da população local permite utilizar estes traços como critério adicional para identificação humana individual com fins periciais. Objetivo: O presente estudo propôs uma análise antropológica da morfologia dental de brasileiros, do Estado do Rio de Janeiro, entre 18 e 30 anos, observando a prevalência de alguns traços antropológicos não-métricos encontrados no arco dental de brasileiros, sua relação com os índices levantados por outros pesquisadores, em amostras de diferentes populações, e seu valor pericial como critério adicional na identificação humana. Metodologia: Foram analisados modelos em gesso de 130 indivíduos (59 homens e 71 mulheres), com os seguintes critérios de inclusão: naturalidade brasileira, com ascendentes brasileiros até segundo grau; presença de, no mínimo, dois elementos dentais hígidos, dentre os dentes-alvo; e ausência de relação de consanguinidade com outros participantes. Foi avaliada a presença de seis traços antropológicos, com frequências étnico-geográficas anteriormente publicadas por outros autores, sendo eles: incisivo em forma de pá, tubérculo de Carabelli, quinta cúspide (tubérculo distal acessório), ausência de cúspide disto-palatina, sexta cúspide (tuberculum sextum), e ausência de cúspide disto-vestibular (molar inferior tetra-cuspidado). Resultados: As frequências obtidas de todos os traços avaliados destoaram das frequências anteriormente apresentadas como referentes aos grupos ameríndio ou sulamericano. A amostra analisada possui pouca semelhança com o chamado complexo dental americano, e nítida influência dos complexos caucasóide e subsaariano, o que está de acordo com os acontecimentos históricos locais
Abstract: The non-metric traits in tooth morphology, for their excellent preservation, and inter-population variation, immune from selection pressure, are known to be one of the major sources of observation for researchers who analyze human variation and its relationship to the populations' biological history. In a forensic context, the knowledge of the local morphological characteristics allows its use as additional criterion for human identification purposes. Objective: This study has proposed an anthropological analysis of tooth morphology of Brazilian individuals from Rio de Janeiro, between 18 and 30 years, listing the prevalence of some anthropological non-metric traits, their relationship with frequencies found by other researchers, in different populations, and its value as additional criterion for in human identification. Methodology: The dental casts of 130 individuals (59 males and 71 females) were examined, with the following inclusion criteria: Brazilian naturality, with Brazilian ascendency until second degree, presence of at least two of the target-teeth healthy, and absence of blood relationship with other participants. We evaluated the presence of six non-metric dental traits with populational frequencies previously published by other authors, as follows: shoveling, Carabelli's cusp, cusp 5 (distal accessory tubercle), hypocone absence, cusp 6, and hypoconid absence. Results: The frequencies of all the traits evaluated differ from frequencies previously presented for Amerindian and South American. The sample has little resemblance to the so called american dental complex, and strong influence of the African Sub-Sahara and European patterns, which is in agreement with local historical events

Full textThere are plenty of difficulties surrounding the radiographs for the comparative techniques on human identification. The lack of soft tissue, the skulls and films positioning are a few of the obstacles faced in anthropological studies. With the objectives to standardize, producing high quality images and reducing adaptations, different exposure times, barriers and other aspects involving radiographs were tested in order to establish a protocol involving periapical and panoramic radiographs of dry skulls. With the help of an acrylic stand, specially designed to position the cranium, panoramic radiographs were primarily taken using different preset configurations, then four materials were tested to compensate for lack of soft tissue: a ice pack, a block of dental wax, a metal plate and finally a film exposed to light and processed that was left between the blank film and the intensifying screen. For the periapical radiographs, Kodak E-speed films were exposed to times from 0.06 to 0.8 second at the upper and lower molars and anterior regions. Clinical film holders were used and kept in position by a metal wire device. The processing times were 45 seconds of development and 10 minutes of fixation. The radiographs were presented to a group of fifteen dentists, of several specialties, who selected the best results and concluding that the panoramic radiographs were best taken with the 63 Kv and 06 mA configurations and two films inside the cassette. For the periapical the exposure times of 0.64 sec for the upper arch and 0.8 sec for the lower achieved the best acceptance. The presented results, allied with the data found in the literature a protocol was also prepared and attached to this research.

Full textThe nose, occupying the middle third of the face, has a marked cognitive influence on facial image. It consists largely of cartilage tissue, muscles, skin and fat, and loses its shape during cadaveric decomposition. The technique of facial reconstruction to restore nasal appearance can influence the recognition of a skull that has no assignable identity and has been the subject of much criticism. The known methods of estimating nasal projection using elements of the skull are lacking in practicality and reproducibility. In this study, we attempted to relate the prosopometric points Rhinion (Rhi, bone), Pronasale (Pn, soft tissue) and Prosthion (Pr, bone) by studying the angle formed by straight lines that connect them, noting the possibility of its use in determining the length of the nose. Two independent and calibrated examiners measured this angle with the help of analysis and image processing software, Image J, version 1.43, directly from cephalometric radiographs, which had been selected from a collection of documentation from the digital archives of four Dental Radiology institutes, located in São Paulo Brazil. Linear measurements were taken by taking into consideration the difference of the value found for the proposed angle and the hypothetical value of 90.00 degrees. The sample consisted of 600 lateral radiographs of the head (of 300 males aged between 24 and 77 years and 300 females, aged 24 to 69 years). The data were analyzed using Microsoft Office Excel 10.0. The results showed that the values for the measurements of both investigators were very close to a perfect linear relationship (r = 0.99).Both gender had the same age distribution. The proposed Rhinion-Pronasale-Prosthion angle varied from 80.00° to 100.00° in both genders and all ages. In males, the distribution of the angle was more symmetrical, centered at 90.88 degrees, while in females there was a higher frequency of values greater than or equal to 90.00 degrees, with a mean of 92.89°. For the linear measurements, the highest relative frequency of the female sample was 0.31 mm and for the male sample it was 0.32 mm that is, each degree of difference between the actual measured angle and suggested one of 90.00° corresponded to the linear measure of about 0.31 mm. Because the Rhinion and Prosthion prosopometric points are easy to find in the skull, the crossing of lines that pass through these points determine the Pronasale point as the apex of the angle. Considering the results obtained, it was possible to use the value of 90.00° for the angle Rhi-Pn-Pr in order to determine nasal projection in Brazilian adults.

Full textThe aim of this study was to evaluate the relationship between the alar cartilage and the pyriform aperture using cone-beam computed tomography (CT) imaging, and the relationship between the morphology of the nose and the vertical skeletal pattern of the face. 96 images of subjects (49 male and 47 female), aged 18-65 years classified according to the vertical skeletal pattern of the face were used in this study. The OsiriX software was used to measure the structures of interest. The facial pattern was obtained according to three techniques: facial index, gonial angle, and facial proportions. From an axial section of the CT imaging, four measurements were performed: nasal width, distance between the alar insertions, extension of the base of the pyriform aperture and width of the pyriform aperture. All measurements were obtained by two calibrated examiners. There is correlation between the nasal width and the breadth of the pyriform aperture, and between the base of the nasal cavity and the distance between the alar insertions. The width of the pyriform aperture proportionally increases more than the nasal breadth. Furthermore, the long face type is associated with nasal width.

Resumo: Os dentes e os arcos dentários podem fornecer, em certas circunstâncias, subsídios imprescindíveis para a solução de crimes e ou fundamentais para o estabelecimento da identidade de um indivíduo. Estes resistem devido à sua localização e dureza a diferentes tipos de agressões. Ocorre que por vezes estes são submetidos a inúmeros tipos de tratamentos restauradores (obturações, próteses unitárias, próteses removíveis, implantes odontológicos, entre outros). Tais restaurações juntamente com a localização, formato, tamanho, ausências, patologias, entre outros constituirão os caracteres sinaléticos utilizados no reconhecimento e identificação dos indivíduos. Em um desastre de grandes proporções (desastres naturais e ou desastres provocados pelo homem), em geral ocorrem incêndios e nestes o ser humano acaba por vezes a ser reduzido a um corpo disforme (carbonizado) mutilado ou não, em outras o mesmo ser humano praticamente desaparece (calcinação), nas duas situações os dentes permanecem viáveis para serem utilizados na identificação, o que diferenciará serão os maiores cuidados que o perito deverá observar durante a coleta dos cadáveres e partes destes. A literatura recomenda sempre que se deve no caso de grandes incêndios, inicialmente localizar os corpos registrando tal situação e discriminar a localização dos pertences pessoais destes, tais como jóias, indumentária, celulares, entre outros. Para os casos de calcinados, recomenda realizar tomadas radiográficas das porções cefálicas ainda no local do acidente visando evitar a destruição dos remanescentes dentários. Sabe-se quanto ao exame dentário que tanto os dentes (esmalte, dentina e cemento) como as restaurações e próteses odontológicas apresentam um determinado comportamento frente às diferenças de temperatura, geradas quando de um incêndio, porém é necessário estabelecer quais são estas alterações frente aos novos materiais odontológicos restauradores. Em vista a estes fatos o presente estudo buscou verificar macroscopicamente e estudar os aspectos dos materiais dentários não metálicos e o amálgama, quando submetidos á energia física calor; avaliar as alterações desses materiais submetidos a 12 níveis de temperaturas compreendidas de 100ºC até 1200ºC, em intervalos de tempo de 15 minutos, analisando e comparando os fenômenos ocorridos nos materiais restauradores odontológicos; discutir os aspectos éticos e legais frentes às perícias de identificação humana. Verificou-se que os materiais restauradores não metálicos , apresentam alterações de cor, de volume, contração (por desidratação) e alterações quanto à superfície externa (carbonizada e até calcinação). O amálgama apresenta alterações de cor, de brilho superficial (apresentando de início pequenos orifícios, entumescendo até a fase da separação dos componentes da liga, terminando somente com a prata no fundo da cavidade). Os dados obtidos são muito semelhantes aos encontrados em arcos dentários de indivíduos carbonizados e permitem ao perito, por comparação, a determinação do tipo de material restaurador utilizado. Tal informação associada com os dados do confronto da documentação produzidas em vida permitirá o estabelecimento da identidade do cadáver

Full textA significant area of identification human being is the Cheiloscopy, word that if it relates to the study, registers and classification of the external mucosa of the lips and the impressions that leave. This inquiry had as objective to describe the ridges of the lip prints, the width of the lips and the disposal of its comissures, by means of queiloscopy study, besides carrying through the identification of individuals through data base formed by queiloscopy fiches. The sample was of 120 students of the course of Odontologia of the Universidade Estadual de Feira de Santana - BA, both the changeable sexos and ages. The research was divided in two stages. In the first stage, of each participant, after TCLE signature, was gotten the impression of the lips in white bristol board, mensured the maximum lip width through ruler milimetrer and carried through photograph of the lips with high resolution digital machine. In the second stage, the 120 fiches proceeding from the queiloscopy study had been divided in 12 groups of 10 participants, in each group were drafted 01 citizen which deposited, after the signature of new TCLE, its determined lip prints in suport (envelop of paper, mirror or fabric of cotton). The researcher did not have knowledge of which had been the authors of the impressions, being this information of exclusive knowledge of the person who orientates. Using it Classification of Suzuky and Tsuchihaschi, the type of ridge more found in the lip prints was of the I' type (Vertical Incomplet), for the Classification of Santos, the thin labial width and the horizontal disposal of the labial comissure had been most common, reaching about 43% and 70%, respectively. The identification was gotten in 100% of the agents of the impressions in the envelops and the mirrors, through the detention of at the very least 12 coincidents points. In fabrics, it can be excluded about 90% of the suspected ones, if not confirming the authors of the impressions for the descaracterization of the points in the tram. Despite the width of the lips and the disposal its comissuras being of easy attainment, the analysis of the labial impression requires a study detailed for the correct accomplishment of the queilograma; what it does not imply in limitation for the use of the Cheiloscopy, as an important alternative system of forensic identification. Possessing the dive rse lips particularitities and being its different impressions of an individual for the other, are concluded that the Cheiloscopy can very be useful to the odontologics connoisseurs in daily skillful practical its, in the Legal Medical Justinian codes, as one of the forms to transfer to evidences, proving a connection between suspected and scene of crime.

Resumo: Um dos mais intrigantes, complexos e controversos desafios da Odontologia Legal é o reconhecimento, registro e análise de marcas de mordidas na pele. Este estudo teve como objetivos: abordar os aspectos relevantes sobre a importância do estudo das marcas de mordidas; produzir informações sobre a ocorrência de casos registrados no Instituto Médico Legal da cidade de Araçatuba-SP, nos últimos cinco anos, envolvendo lesões ocasionadas por mordidas humanas; avaliar comparativamente quatro materiais de moldagem para estudo de marcas de mordidas na pele e testar a aplicabilidade da técnica proposta, por meio de um caso simulado. Foram analisadas 7.550 ocorrências policiais do período de 2001 a 2005. Verificou-se: idade das vítimas, parentesco com o agressor e ocorrência de lesões produzidas por mordidas humanas, bem como, o local mais acometido por tal ferimento. Nas etapas laboratoriais foram utilizados cinco suínos abatidos, com idade média de oito semanas e pesando cerca de seis quilos. Eles foram divididos ao meio e, em seguida, entre dez voluntários foi feito um sorteio sendo que quatro sorteados morderam cada uma das partes, sem conhecimento do pesquisador. A análise das mordidas foi feita de acordo com as normas da ABFO. Foram utilizados os materiais de moldagem: Alginato, Poliéter, Silicone de Condensação e Silicone de Adição. Durante o estudo de caso, a partir dos modelos de gesso e das partes mordidas, foi feita a identificação dos agentes das mordidas, utilizando a técnica da Análise Métrica, e, como controle, a técnica de sobreposições de imagens com uso do Software Adobe Photoshop 7.0. Foram encontrados quarenta e dois casos envolvendo, dentre outros tipos de lesões, as marcas de mordidas. O total de lesões encontradas foi de cinqüenta e seis mordidas: trinta e três pessoas foram vítimas (31 do sexo feminino e 11 do sexo masculino) e oito foram os autores das agressões (todos homens).
Abstract: One of the most intriguing, complex and controversial challenges of the Legal Odontology is the recognition, registers and analysis of bite mark. This study objectives was: observe the relevant aspects about bite marks analyses importance, using a literature review; demonstrate the prevalence of bite marks in domestic violence crimes involving physical aggression with were collected data in the Police Station of the Woman's Defense in Araçatuba (São Paulo/Brazil); evaluate comparatively four impressions materials for bite marks analysis on skin and test the proposed technique applicability, with a simulated case. 7.550 occurrences policemen of the period from 2001 to 2005 were analyzed. It was verified: the victims' age, relationship with the aggressor and occurrence of lesions produced for bitten human, as well as, the place more attacked by such wound. In the laboratorial phase, it was used five pigs, with eight weeks ages. They were cute, soon afterwards, among ten volunteers it was made a draw and four raffled they bit each one of the parts, without the researcher's knowledge. The analysis of the bites was made in agreement with the norms of ABFO. The molding materials were used: Alginate, Poliéter, Condensation Silicon and Addition Silicon. During the case study, starting from the models of plaster and of the bitten foods, it was made the agents' of the bites identification, using the technique of the Metric Analysis, and, as control, the technique to put upon of images with use of the Software Adobe Photoshop 7.0. They were found forty two cases involving, among other types of lesions, the marks of bitten. The total of found lesions was of fifty six bitten: thirty three people were victims (31 female and 11 male) and eight were the authors of the aggressions (all men).

Full textForensic Sciences employ Forensic Facial Reconstruction technique to increase possibilities in human recognition. After anthropological analysis, the face can be created on the skeletonized skull and published in the media. There are several methodologies for facial modeling and facial features as well as multiple soft tissue thicknesses data that aid in facial contour. In order to investigate whether a methodology allows more recognition and greater resemblance to a person, this study aimed to compare manual facial reconstructions made with two approaches of filling facial soft tissue (American and Manchester methods) and two approaches to predict the eyes, nose, mouth and ears. This study also intended to compare facial reconstructions carried out with four Brazilian soft tissue thicknesses data, that were developed by previous studies considering the possibily of merging these data for Forensic Reconstruction purpose. A fourth aim was to determine whether sex and anatomical or Forensic knowledge of assessor can influence in frequency of recognition. This study was divided into two phases. In the first phase, two reconstructions were performed for two targets (one male and one female) with American and Manchester methods and applying two guides for eyes, nose, mouth and ears. The reconstructions were evaluated by forty assessors (both sex, divided into four groups - undergraduated students in dentistry who did not study Forensic Dentistry, undergraduated students in dentistry who have gone through the subject of Forensic Dentistry, experts in Forensic Dentistry and individuals who did not have knowlegde of human anatomy) through the recognition and resemblance tests. For female target, frequencies of recognitions were 20% and 10% for American and Manchester methods, respectively; for male target, frequencies were 35% and 17.5%, with significant differences between the proportions of correct responses. Regarding resemblance rates, medians were less than 3 (on a scale from 1 to 5); however, it was found an exception for the sculpture made with the American method for male target, which had median 3. Thus, American method was used for the reconstructions of phase II. In this second phase, facial reconstructions for four targets (two male and two female) were obtained with the American method, considering the four Brazilian soft tissue thicknesses data. Sixteen facial reconstructions were evaluated by a hundred and twenty assessors, also through the recognition and resemblance tests. As in phase I, it was considered the sex and the group of assessors. For the first target, ratios were significantly higher for reconstructions made with data obtained from cadavers (44% and 38%) compared with those obtained from imaging. For the target 4, the proportion of correct responses with data from cadavers (Tedeschi-Oliveira et al.) and from Magnetic Resonance Imaging were significantly higher compared to reconstructions with data from Computer Tomographic scans data. Regarding resemblance, only target 1 showed significant differences in frequency of slight resemblance between reconstructions. In addition, nor sex, nor the knowledge of human anatomy from assessor has influenced the frequency of correct responses. It is also expected that the proposed table be employed for Brazilians.

Resumo: O índice de Carrea constitui uma importante ferramenta na estimativa da estatura humana, necessitando para sua aplicação apenas que alguns elementos dentais anteriores inferiores estejam preservados. No entanto, nos casos em que a mandíbula é acometida por um trauma, uma patologia ou por situações diversas, o uso da técnica torna-se inviável. Com isso, ampliar a utilização do índice de Carrea, estendendo-o aos elementos superiores, aumentaria as chances de se realizar o método, principalmente nos casos em que apenas o crânio é encontrado. Diante disso, o presente estudo teve como proposição testar um novo denominador no índice de Carrea, para que o mesmo possa ser utilizado no arco superior, visando um novo recurso para se estimar a estatura humana. Além disso, objetiva-se comparar os percentuais de acerto obtidos entre o arco inferior e superior. Para tanto, foi realizado um estudo com 378 modelos em gesso, sendo 189 superiores e 189 inferiores de arcos dentais correspondentes, pertencentes a alunos do curso de Odontologia da Universidade Federal da Paraíba, de ambos os sexos e com idades entre 18 e 30 anos. A estatura dos participantes foi estimada mensurando, com um paquímetro digital, os incisivos central e lateral e o canino, dos arcos superiores e inferiores, bem como dos hemiarcos direito e esquerdo. A partir dessas medidas, foram estimadas, por meio do índice de Carrea, as alturas máxima e mínima com base nos arcos inferiores. Para os arcos superiores foi utilizada uma modificação no denominador da fórmula original de Carrea, de valor 2 para o valor 2,55, de forma que a mesma se adequasse às medidas da maxila. Os valores obtidos foram comparados à estatura real dos participantes, previamente mesurada com um antropômetro. No arco superior, verificou-se diferença estatisticamente significante entre os posicionamentos dentais no sexo masculino e nos hemiarcos direitos, sendo os apinhados o maior percentual de acerto (65% e 65,2%, respectivamente). A avaliação interarcos proposta entre os sexos, para os três tipos de posicionamento dental, demonstrou percentual de acerto estatisticamente significante no sexo feminino entre os hemiarcos normais, com os inferiores apresentando percentual maior (70,0%) em relação aos superiores (42,3%). Já entre os hemiarcos, a diferença estatística pôde ser observada nos lados direito e esquerdo, apenas no posicionamento normal, com os inferiores demonstrando percentuais de acerto maiores (61,5% e 67,6%, respectivamente). Dessa forma, conclui-se que, embora o percentual de acertos no arco superior não tenha sido significante, o método poderá ser utilizado como subsídio para a estimativa da estatura
Abstract: Carrea's index is an important tool in human stature estimation, and requires for its use only some lower anterior teeth preserved. However, in cases of mandibular damage - by trauma, pathology or any other condition - the use of the method becomes impossible. Therefore, expand the use of Carrea's index, extending it to upper dental elements, increases the applicability of the method, especially in cases where only the skull is recovered. Thus, the present study aimed to test a new denominator for Carrea's index, so that it can be used in the upper jaw, which provides a new resource for human stature estimation. The study was conducted with 378 cast models - 189 higher and 189 lower arches - of dentistry students from the Federal University of Paraíba, of both sexes and aged between 18 and 30 years. The stature of the participants was estimated by measuring, with a digital caliper, the central and lateral incisors and canine from upper and lower arches, both sides. From these measurements, the maximum and minimum stature was estimated, according to Carrea's index. Moreover, it was aimed to compare the sucess rates between the upper and lower arches. For the upper arches a new denominator of Carrea's original formula, from 2 to 2.55, so it would fit the the maxilla's measures. The values obtained were compared to the real stature of the participants, previously measured with an anthropometer. In the maxillary arch, there was a statistically significant difference between the teeth alignment in males and in the right hemiarch, with the crowded hemiarches showing the greatest accuracy (65% and 65.2% respectively). The interarch evaluation proposed between the sexes, for the three types of dental alignment proved percentage of success statistically significant in females between the normal hemiarches, with the lower arch showing a higher percentage (70.0%) compared with the upper one (42.3%). Among the hemiarches, statistical difference was observed in right and left sides only in normal position, with the lower arch showing greater success rate (61.5% and 67.6% respectively). It can be stated that although the percentage of success in the upper arch was not significant, the method proposed can be used as additional criteria for the estimation of stature

Resumo: Objetivo: comparar o desempenho de graduandos em Odontologia e pósgraduandos em Odontologia Legal, no sentido de realizar a identificação humana por meio da análise de fotografias de sorriso. Material e Métodos: foram coletados dois tipos de fotografias (de sorriso e intrabucal) usando máquinas digitais, bem como dados sobre submissão ou não a tratamento ortodôntico e sobre a presença de tratamento odontológico nos dentes anteriores, por meio de um questionário, respondido por 101 acadêmicos de Odontologia da UNIP-GO, com o intuito de simular casos de identificação humana, comparando-se imagens produzidas em vida (fotografia de sorriso) e pós-morte (fotografia intrabucal). A amostra inicial foi dividida em dois grupos: I) estudantes submetidos a tratamento ortodôntico (testes A e B); e II) estudantes sem histórico de tratamento ortodôntico (testes C e D), tendo sido selecionados 20 pares de imagens de cada grupo. Em seguida, cada grupo foi novamente dividido em dois subgrupos, contendo 10 fotografias de sorriso e 10 fotografias intrabucais, que foram numeradas e montadas em quatro mostruários distintos. Para cada mostruário, foi sorteado um único número, sendo buscada a sua imagem correspondente, que foi inserida numa folha resposta. Assim, foram montados quatro testes (A, B, C e D), os quais foram aplicados a 12 graduandos em Odontologia e a 12 pós-graduandos em Odontologia Legal da FOP-UNICAMP, que analisaram a fotografia sorteada (de sorriso ou intrabucal) e a correlacionaram com uma das 10 imagens presentes no mostruário correspondente, apontando os critérios de inclusão que foram relevantes para se chegar à conclusão final. Resultados: todos os sujeitos da pesquisa, em ambos os grupos, acertaram o teste A (análise de uma fotografia de sorriso num grupo de 10 intrabucais). Os testes B (análise de uma fotografia intrabucal num grupo de 10 de sorriso) e D (análise de uma fotografia de sorriso num grupo de 10 intrabucais) tiveram 91,6% de acerto dentre os estudantes de pós-graduação; e o teste C (análise de uma fotografia intrabucal num grupo de 10 de sorriso) teve 83,3% de acerto entre os estudantes de graduação. Dentre os critérios de inclusão para se chegar ao resultado de identificação odontolegal pela análise de fotografias de sorriso, a morfologia das incisais dos dentes anteriores foi o critério mais citado tanto pelos estudantes de graduação (83,3%) como pelos estudantes de pós-graduação (72,9%), nos 48 testes realizados em cada grupo. O teste Exato de Fischer não mostrou haver associação estatisticamente significante entre as variáveis estudadas ou entre os testes aplicados. Conclusão: a grande maioria dos graduandos em Odontologia e dos pós-graduandos em Odontologia Legal mostrou-se apta a efetuar uma identificação humana por meio da análise de fotografias de sorriso, considerando a grande variedade de características odontológicas potencialmente evidenciáveis nos dentes anteriores
Abstract: Aim: to compare the performance of undergraduate students of Dentistry and postgraduate students of Forensic Odontology with the purpose of proceeding to human identification through the analysis of photographs of the smile. Material and Methods: using digital cameras, two types of photograph shots (one of the smile and the other of the oral cavity) were collected, as well as data about having or not undergone orthodontic treatment and about the presence of dental treatment in anterior teeth, through the application of a questionnaire answered by 101 students of Dentistry from UNIP-GO, in order to simulate human identification cases, by comparing the images produced in life (photograph of the smile) to the postmortem ones (intraoral photograph). The initial sample was divided into two groups: I) students who had undergone orthodontic treatment (tests A and B); and II) students with no history of orthodontic treatment (tests C and D), and 20 pairs of images from each group were selected. Then, each group was again divided into two subgroups, containing 10 photographs of the smile and 10 intraoral photographs which were numbered and mounted on four separate showcases. For each showcase, one single number was drawn, and the corresponding image was searched, which was inserted into an answer sheet. Thus, four tests were mounted (A, B, C and D) and they were applied to 12 undergraduate students of Dentistry and to 12 postgraduate students of Forensic Odontology from FOP-UNICAMP who analyzed the picture that was drawn (photograph of the smile or intraoral photograph) and correlated it with one of the 10 images present in the corresponding showcase, pointing out the inclusion criteria that were important for reaching a final conclusion. Results: all the subjects of the research, in both groups, correctly answered to test A (analysis of a photograph of the smile in a group of 10 intraoral photographs). The tests B (analysis of an intraoral photograph in a group of 10 photographs of the smile) and D (analysis of a photograph of the smile in a group of 10 intraoral photographs) had 91.6% success among postgraduate students; and test C (analysis of an intraoral photograph in a group of 10 photographs of the smile) had 83.3% success among undergraduate students. Among the inclusion criteria to achieve the result of Forensic Odontology identification through the analysis of photographs of the smile, the morphology of the incisor part of anterior teeth was the aspect most often quoted by undergraduate students (83.3%) and also by postgraduate students (72.9%), in the 48 tests applied to each group. The Fisher exact test did not show statistically significant association between the studied variables or between the tests applied. Conclusions: the vast majority of the undergraduate students of Dentistry and of the postgraduate students of Forensic Odontology have shown to be able to make a human identification through the analysis of photographs of the smile, considering the wide variety of dental characteristics potentially demonstrable in anterior teeth

Resumo: O processo de identificação humana envolve diferentes etapas, contexto no qual se faz necessário o aprimoramento das técnicas tradicionais e o desenvolvimento de novas metodologias aplicáveis na rotina da prática pericial. É através da investigação do gênero biológico, precedida da determinação da espécie, que se dá o passo inicial no delineamento do perfil de vítimas não-identificadas. Ao encontro dos exames antropológicos, as técnicas de DNA consolidaram-se como adjuvantes e certificadoras; porém, trazem consigo limitações atinentes ao custo, agilidade e aplicabilidade. O presente estudo buscou investigar o gênero biológico, através do isolamento do gene amelogenina. Para tanto, foram utilizadas 52 polpas dentais obtidas de dentes extraídos de corpos em decomposição, as quais foram submetidas à extração do material genético por meio da resina quelante Chelex 100® (BioRad) e à amplificação pela reação em cadeia da polimerase (PCR). Após eletroforese com seqüenciador automático (Applied Biosystems 3130 Genetic Analyzer®), os picos foram obtidos, e os resultados interpretados como AMEL X para indivíduo feminino (106 pb), e AMEL Y para indivíduo masculino (112 pb). Não foi possível determinar o gênero biológico em 15,4% (n=8) dos dentes e não houve influência do sexo na viabilidade do material coletado para a determinação do gênero (p = 0, 072). Quanto aos grupos dentais, divididos em molares, pré-molares, caninos e incisivos, os mesmos não exerceram influência na obtenção dos resultados (p = 0,892). Houve concordância de 95,5% (n=42) entre a determinação do gênero biológico e o gênero real dos indivíduos que compuseram a amostra (Kappa = 0, 909). Dentre aqueles do gênero masculino houve discordância de 5,6% (n=2) entre o sexo real e o sexo obtido pela amplificação, revelando resultado de falso-feminino, ou seja, indivíduos masculinos com genótipo XX (AMEL X). Concluiu-se que, apesar da amostra ser composta por material degradado, a amplificação da amelogenina apresentou resultados satisfatórios na investigação do gênero biológico, mostrando-se como uma metodologia de ótimo custo-benefício capaz de complementar estudos antropológicos de identificação humana
Abstract: The process of human identification involves differents stages, in wich context it is necessary to the improvement of tradicional techniques and the development of new methods applicable in forensic practice routine. It is througth the investigation of biological gender, preceded by the determination of species, wich takes the initial step in designing the profile of unidentified victms. To meet the anthropological examination, DNA techniques established themselves as adjuvants and certifiers, but bring with them limitations pertaining to cost, flexibility and applicability. This study aimed to investigate the biological gender by isolating the amelogenin gene. For this purpose, we used dental pulp obtained from 52 teeth extracted from decomposing bodies, wich were genetic material extracted throught the chelating resin Chelex 100® (Bio Rad) and amplification by polymerase chain reaction (PCR). After electrophoresis on automatic sequencer (Applied Biosystems 3130 Genetic Analyser®), the peaks were obtained and the results interpreted as AMEL X for females individuals (106 pb) and AMEL Y for male individuals (112 pb). Could not be determined the biological gender of 15,4% (n = 08) of the teeth and there was no influence of gender on the viability of the material collected for the determination of sex (p = 0,072). As dental groups, divided in into molars, premolars, canines and incisors, they were not influential in obtaining the results (p = 0,892). There was concordance of 95,5% (n = 42) between the determination of the actual biological gender and the gender of sampled individuals (Kappa = 0,909). Among those of males, there was disagreement of 5,6% (n = 02) between real sex and sex obtained by amplification, revealing results of false-female, or males subjects with XX genotype (AMEL X). We concluded that, althought the samples were composed of degraded material, the amplification of amelogenin presented satisfactory results in the investigation of biological gender, showing himself as a cost-effective methodology, capable of complement anthropological studies in human identification

Full textThe analysis of DNA can be considered major technical advances for criminal investigation since the discovery of fingerprints. Its emergence has brought new paradigms for the criteria used in the formulation of culpability in the field of criminal law, as well as the establishment of legal certainty in relations of affiliation, field of civil law. It was incorporated in routine forensic police from the countries of first world and beginning to be introduced in the context expert in some Brazilian states. However, the use of these techniques of genetic identification, gives quality requirements and excellence laboratories that perform them. Therefore, setting standards, setting principle and creating systems of accreditation and certification have become absolutely necessary. Taking into account the growing influence of the DNA in the forensic context, this study aimed to know the Brazilian reality on this technology and the importance of the role of surgeon-dentist in the forensic team. For this reason, attempts were made to contact the department\'s official identification center of the capital of each of the twenty-six Brazilian states than the Federal District. Participated in the survey 17 (seventeen) States (Minas Gerais, Goiás, Rio Grande do Sul, Para, Pernambuco, Alagoas, Paraná, São Paulo, Paraíba, Bahia, Rio de Janeiro, Roraima, Amapá, Maranhão, Rio Grande do Norte, Ceara and Tocantins). Data collection was conducted through a questionnaire. From this could be established that the majority of services (88%) made use of the technique of genetic identification. Among these, only the Rio Grande do Norte do not adopt protocols for collection and storage of biological samples. The blood is the biological sample of choice, but in cases of carcass or when the corpse is carbonized and / or advanced state of decomposition, the teeth are used as a source of DNA. Usually the samples are collected from sexual crimes. Despite the bite marks are frequently found evidence in such crimes, the collection of saliva (swab) is performed only in 43% of the states. Among the various categories of professionals who make up the team of forensic DNA, pharmacists are stressed (43%). They certificate of accreditation of laboratories only 50% (São Paulo, Rio de Janeiro, Paraná, Rio Grande do Sul, Bahia, Roraima and Amapá). This work could understand the way in which these services are structuring and developing this technology. Through the results of this study was to check the growing influence exercised by the technique of DNA in cases of identification, the importance of the many occupational, since the contribution of each area and the methodology employed in the process will be influenced by the condition of biological material submitted for review and emphasize the importance of specific knowledge of forensic dentist, mainly because of dental elements, in cases of advanced decomposition and charring, and the saliva, bite marks on this, are potential sources of DNA.

Full textForensic facial reconstruction (FFR) is a research field that intends to estimate the face of an individual through a skull. Mean soft tissue thickness values, of different cranial landmarks, often obtained through needle puncture, are used as references. Lately, some digital methods, such as Magnetic resonance and Fan-beam Computer Tomography have been offering new resources to forensic analysis. Cone-Beam Computer Tomography (CBCT), differs from others, by allowing the volumetric acquisition of a sitting patient. In the study of occlusion and orthodontic, is usual to associate volume and functional features to different facial types, therefore the objective is to establish a CBCT soft tissue measuring method, for points used for FFR, verifying the existence of significant differences of soft tissue pattern in distinct facial types. A guideline was created to allow observers to measure soft tissue of 32 landmarks (10 sagittal and 11 bilateral), usually found in FFR researches. Precision was accessed through landmarks placing tests in 5 exams, inter-observers and intraobservers intraclass correlation in 10 exams. The use of the software Osirix® was supported by the comparison with Nemotec® in 25 exams. Visual tests were performed through a computer tomography from a skull with resin spheres placed through the manual approach. The 100 subject sample were divided into gender and then into vertical facial types of long face (LF), short face (SF) and normal face (NF), and in horizontal types: CL I, II, III. Normality statistical tests were applied and the difference between groups was tested. The sample was divided in 50 men: 13 NF, 29 LF, and 10 SF, as 20 were Class I, 14 CL II and 16 CL III. The 50 women were divided into 16 NF, 24 LF and 10 SF, as 24 were Class I, 18 CL II and 8 CL III. The method was considered adequate, as after little calibration was needed to allow observers to place landmarks with similar precision. The mean intraclass correlation was considered strong between software (0.75) and observers (0.8), and very strong on intra-observer (0.9). Visual tests pointed out good level of coincidence between manual and digital methods with advantage to the digital due to the available computer tools. The average measures differed between male and female gender, as thicker depths were observed in men in all landmarks, with exception to the Lateral Orbits. The small amount of difference, observed among facial types was considered insufficient to sustain the use of new reference charts. Nevertheless, morphological features could be noticed, especially among male subjects. The depth of landmarks placed over the mandible presented statistical differences, demonstrating that class III, and or long face facial types have less tissue in those areas than class II and short-faced patients.

Resumo: Em praticamente todos os casos onde somente se dispõe de remanescentes ósseos, faz-se necessário a realização de perícias de identificação antropológica. Tais perícias são realizadas, geralmente, no crânio e/ou nos ossos da pelve, pois estes fornecem elementos de presunção do gênero, da raça e da idade. Porém, há casos onde somente se encontram peças ósseas isoladas, impossibilitando a obtenção do crânio. Para estes casos, a maioria das pesquisas brasileiras, que tiveram como objeto de estudo o crânio, não possibilitariam a determinação do gênero em ossos longos tomando como base a amostra nacional. Na presente pesquisa foram avaliados os ossos longos do corpo, quanto ao dimorfismo e estabeleceu-se um modelo matemático que permita a determinação do gênero por meio de ossos longos. Após os estudos de 200 ossadas (100 de indivíduos femininos e 100 de indivíduos masculinos), todas, com gênero, idade, e origem, definidos. Destaca-se que em relação à cor da pele, muitas ossadas achavam-se sem a devida especificação no livro de obituários existentes no IML Paes de Barros de Cuiabá-MT. Concluiu-se que os ossos longos pesquisados (Rádio, tíbia, fíbula, fêmur e dedo anular da mão), são dimórficos. O modelo matemático elaborado foi (Logito = -0,2113 ¿ 0,0144 * tibia + 0.1469 * anular) para a determinação do gênero, com índice de concordância do modelo de 74% entre os gêneros estimados e observados. Pode-se afirmar que o uso do modelo matemático elaborado torna mais confiável o exame antropológico e permite uma maior praticidade, quando do seu uso. Porém, o uso desta deve ser feito com ponderação, tendo sempre como premissa o fator idade, cor da pele, biotipo e o grupo sócio-econômico a que pertenceu a ossada

Full textThe concern with the identification, that is the process by which the identity is determined, is quite old. Currently, the social relations or civil, criminal, administrative and commercial requirements need its evidence. The identification of deceased persons is essential not only to assuage the emotional needs of their friends and family, but also to allow legal actions related to death. Unfortunately, situations often occur when bodies arrive at the Medico-Legal Institutes in a state of putrefaction or skeletonization, and are not identified. In such situations, anthropometric analysis to estimate, for example, age, gender and height, are of great value. In these cases, forensic facial reconstruction is very important because it may serve to recognize and therefore increase the chances of identification. The three-dimensional forensic facial reconstruction can be manual or digital. The digital forensic facial reconstruction was made possible with the advent of Information Technology, medical imaging and new 3D image and reconstruction softwares. To perform facial reconstruction, data on the thickness of the soft tissues of the face are necessary. There is no literature records of facial reconstruction works carried out with digital data of soft tissues obtained from samples of Brazilian subjects. There are two tables of thickness of soft tissue published for the Brazilian population: one obtained from measurements performed in fresh cadavers (fresh cadavers pattern), and another from measurements on magnetic resonance imaging (magnetic resonance pattern). The aim of this study was to perform three different characterized digital forensic facial reconstructions (with hair, eyelashes and eyebrows) of a Brazilian subject (based on an international pattern and two national patterns for soft facial tissue thickness), and evaluate the digital forensic facial reconstructions comparing them to photos of the individual and other nine subjects. We used DICOM images of a computed tomography (CT) donated by a volunteer that, once converted, were used for the realization of the digital facial reconstructions. Once we\'ve performed the three reconstructions, they were compared with photographs of the volunteer who had his face reconstructed and of nine other subjects. Thirty examiners participated in this recognition attempt. The target subject, who had his face reconstructed, was recognized by 26.67% of the examiners in the reconstruction performed with the national Magnetic Resonance Pattern, 23.33% in the reconstruction performed with the national Fresh Cadavers Pattern of and 20.00 % in the reconstruction performed with the International Pattern, and the target-subject was the most recognized subject in the first two patterns. The correct recognitions of the subject indicate that the digital forensic facial reconstruction, carried out with parameters used in this study, may be a useful tool, with one or more subjects recognized to achieve a positive identification.

Resumo: Hoje no Brasil cerca de 50 milhões de pessoas têm planos de saúde. Destas, 10 milhões possuem planos exclusivamente Odontológicos. Com essa consolidação dos planos Odontológicos, uma nova carreira foi aberta para o cirurgião-dentista, a do Auditor Odontológico. O fluxo de competitividade econômico-financeiro deste mercado exige do Auditor Odontológico a verificação dos procedimentos que se pagam, evitando abusos por parte do prestador de serviços, sem, contudo, esbarrar em questões éticas que tangenciam esta atividade. Estas avaliações devem ser executadas por profissionais capacitados, que apresentem além do conhecimento técnico-científico, atributos pessoais como imparcialidade, prudência e diplomacia, entre outros. A falta de um protocolo padrão para a realização de auditorias acaba dificultando a atuação destes profissionais, pois ocorrem distorções nas avaliações. Assim a presente pesquisa teve como objetivos relacionar as não conformidades (Glosas) verificadas aos procedimentos odontológicos das diversas áreas da Odontologia (dentística, periodontia, e demais especialidades odontológicas), mostrando em que área (s) de atuação estão concentradas o maior número de glosas; verificar a viabilidade econômica das auditorias clínicas (Presenciais) em todos os tratamentos solicitados, e como último objetivo a pesquisa esclarece a intervenção do estado, por meio da Agência Nacional de Saúde (ANS) no mercado de saúde suplementar, revisando suas normas atuais para as operadoras de planos odontológicos, e a sua responsabilidade na remuneração da classe odontológica. Este trabalho avaliou 2.283 relatórios de auditorias iniciais arquivados em uma cooperativa de trabalho Odontológico no período de 2002 a 2008 nos meses de janeiro a dezembro, selecionadas aleatoriamente, e analisadas por estatística descritiva. Verificou-se que a dentística é a especialidade responsável por mais da metade das glosas verificadas na amostra, que a auditoria clínica é condenável em todos os orçamentos enviados à operadora pelo cirurgião-dentista, que a influência da agência nacional de saúde (ANS) no mercado de saúde suplementar influencia diretamente na manutenção das operadoras de pequeno e médio porte no mercado de saúde suplementar. Concluiu-se que a dentística é a especialidade clínica com a maior quantidade de glosas na amostra; comprovou a inviabilidade da auditoria clínica (presencial) em todos os tratamentos solicitados, devido à disparidade entre os valores pagos aos auditores e aos valores totais das não-conformidades; esclareceu a atuação da ANS no mercado de Odontologia suplementar, e que há um desequilíbrio na relação financeira entre operadoras, usuários e cirurgiões-dentistas
Abstract: Today in Brazil about 50 million people have health insurance. Of these, 10 million are exclusively Dental plans. With this consolidation of Dental Plans, a new career was opened to the dentist, the Dental Auditor. The flow of financial and economic competitiveness of this market requires the Auditor Dental verification procedures that are paying to avoid abuse by the service provider, without, however, run into ethical issues that touch on this activity. These assessments must be performed by trained professionals, Who present beyond the technical and scientific knowledge, personal attributes such as fairness, prudence and diplomacy, among others. This study evaluated 2283 treatments audited and filed in a cooperative working Dentistry during 2002 to 2008, relating to nonconformities (Glosses) requested the types of dental procedures (restorative procedures, Periodontics, Dental and other specialties). Relating the Glosses, too, the number of Service Units (U.S.), which show the real value of these glosses, and how the carrier failed to pay unnecessarily for professionals. The survey also was intended to verify the cost effectiveness of clinical audits (presence) in all treatments requested. As a final objective the research studied the intervention of the state, through the National Health Agency (ANS) in the health plan market, revising its current guidelines for operators of dental plans, and the possible consequences of economic / financial, especially for operators smaller. We observed that dentistry is the specialty responsible for more than half of the glosses found in the sample, clinical audit is wrong on all budgets submitted to the carrier by the surgeon - dentist, the influence of the ANS health plan market, with that agency a direct influence in the maintenance of the operators of small and midsize market health insurance. It was concluded that light-cured resin restoration of a face are the procedures with the greatest number of glosses in the sample; the impracticality of clinical audit (in person) in all treatments requested due to the disparity between the amounts paid to auditors and the total values of the non-conformities; discuss the role of the National Dental Health in the market further

Full textForensic Facial Reconstruction (FFR) is an area of Forensic Anthropology that seeks to approximate the appearance of an unknown individual by reconstructing soft tissues over ones skull after an anthropological analysis. The FFR published in the media aims at a recognition, which can trigger a process of human identification. Knowing the relationship between hard and soft tissues is crucial to increase the accuracy of FFRs. In this study, we sought to gather anthropometric information on the mouth and its proportions. Two samples were taken from a collection of CBCT scans. Sample 1 (n=327) consisted of men (n=127) and women (n=185) aged between 11 and 81 years old, divided into six age groups and verified the linear distances defined by anatomical landmarks in soft tissue: vermillion height, mouth width, the proportion between these and the possibility of estimating mouth width from the intercanine distance. Sample 2 (n=108) consisted of men (n=40) and women (n=68) aged between 20 and 81 years old, divided into three age groups, and verified the proportions between the vermilllions of the mouth, mouth width and linear distances marked in bony craniometrical landmarks. The measurements were made in OsiriX software and the results were analyzed by averages, standard deviations and differences between the averages. For sample 1, vermillion height corresponded to approximately 26% of mouth width, in both genders, with a tendency to decrease over time. Mouth width increased over time in men, and kept stable values in women. The intercanine distance corresponded to about 75% of mouth width in men, and 80% of the mouth width in women. For sample 2, the distance between the landmarks infradentale and supramentale and was on average 55% of the vermillion height in both genders, and the distance between the landmarks philtrum medium and supradentale was about 85% of the vermillion height in men and about 88% of the same measure, in women. The distance between the mental foramina was on average 97% of the mouth width in women, and 93% of this distance in men. Gathering anthropometric information on the mouth for the Brazilian population can contribute to increase the accuracy of FFRs and assist human identification.

Resumo: A pigmentação rosada é uma alteração cromática dos dentes, que pode estar relacionada a mortes súbitas e violentas, resultante do extravasamento sanguineo a partir da polpa dentária, com penetração da hemoglobina ou seus subprodutos no interior dos túbulos dentinários. Fatores como a umidade, temperatura e a posição em que são encontrados os corpos são considerados como coadjuvantes no desenvolvimento do fenômeno. Neste trabalho foram utilizadas duas amostras com o objetivo de analisar as fases de formação desta alteração cromática, sendo uma amostra constituída de dentes decíduos naturalmente rosados e a outra de dentes decíduos cuja pigmentação rosada foi reproduzida experimentalmente. Após a indução da pigmentação rosada, através da injeção sanguínea a partir do ápice radicular, quando da observação da modificação cromática os elementos dentários foram submetidos em diferentes dias a uma análise histológica e outra espectrofotométrica. Os resultados obtidos através das duas análises permitiram-nos concluir que a hemoglobina íntegra é a responsável pela alteração de cor, os seus subprodutos não têm papel fundamental no desenvolvimento do fenômeno e que a sua degradação não acontece de forma única e é mais lenta do que previamente se pensava
Abstract: Pink pigmentation is a chromatic change of teeth that may be related to sudden and violent deaths. It is caused by blood flow out trom dental pulp, with the penetration of hemoglobin and its sub products into dentinal tubules. Factors such as temperature and the position of the bodies are considered to help the development of such situation. This research used two samples to analyze the phases of that chromatic change. One of the samples was a group of naturally pink deciduous teeth. The other group was deciduous teeth that the pink pigmentation was reproduced experimentally. After reproduction of pink pigmentation, these teeth were histological and spectrophotometric analyzed in different days. Therefore it was concluded that the hemoglobin is responsible for color change and its degradation happens slower that was earlier thought

Resumo: A ciência e a tecnologia vêm se sobrepujando constantemente e seus avanços repercutem nas deliberações do Poder Judiciário. Decisões sobre paternidade baseadas em técnicas, atualmente suplantadas pelo avanço da ciência, têm sido questionadas judicialmente, colocando em evidência a atividade do perito judicial. Nesse contexto, o presente trabalho de pesquisa teve por objetivo investigar de que maneira tem sido interpretada a responsabilidade do perito que emitiu laudos com resultados de exames de paternidade realizados em época anterior à utilização dos exames de DNA, para esse mesmo fim. Para o desenvolvimento deste trabalho de pesquisa foram analisados 200 exames de investigação de paternidade, realizados entre os anos de 1994 a 2001, pela técnica dos antígenos eritrocitátios e leucocitátios e 30 exames de investigação de paternidade realizados no ano de 2006, empregando-se a técnica de DNA, todos realizados na FOP-UNICAMP - Faculdade de Odontologia de Piracicaba, Departamento de Odontologia social, Área de Odontologia Legal e Deodontologia. Foram analisados, também, os aspectos jurídicos dos exames de paternidade avaliando 20 julgados ocorridos no perído entre 1991 e 2006, pelos tribunais pátrios, para verificar como tem sido vista a responsabilidade do perito pelos nossos julgadores. Toda pesquisa foi realizada na Faculdade de Odontologia de Piracicaba -UNICAMP. Atingido o seu termo, este trabalho de pesquisa científica permitiu concluir que a utilização dos exames pelos antígenos eritrocitários e até mesmo dos antígenos leucocitários, levava a um nível de credibilidade absoluta apenas quando excluíam a paternidade acusada; que os exames de DNA oferecem um índice de certeza de 99,99% em casos de investigação de paternidade, que os tribunais passaram a flexibiliar a coisa julgada material em ações nagatórias de paternidade com pedidos baseados em exames de DNA e que o perito, tendo se valido dos limites impostos pela técnica disponível em cada época, não podia ser responsabilizado pela reforma da sentença em ação negatória de paternidade, com base no exame de DNA
Abstract: The science and the technology come if constantly surpassing and its progresses rebound in the deliberations of the Judiciary Power. Decisions on paternity set in techniques, now supplanted by the progress of the science, they have been questioned judicially, placing in evidence the activity of the judicial expert. In that context, the present research work had for objective to investigate that way has been interpreted the responsibility of the expert that emitted legal issue with results of exams of paternity accomplished in time previous to the use of the exams of DNA, for that same end. For the development of this research work 200 exams of investigation of paternity were analyzed, accomplished among the years from 1994 to 2001, by the technique of the antigens eritrocitátios and leucocitátios and 30 exams of investigation of paternity accomplished in the year of 2006, being used the technique of DNA, everybody accomplished in FOP-UNICAMP - Ability of Dentistry of Piracicaba, Department of social Dentistry, Area of Legal Dentistry and Deodontology. They were analyzed, also, the juridical aspects of the exams of paternity evaluating 20 judged happened in the period between 1991 and 2006, for the tribunals of the homeland, to verify as the responsibility of the expert has been seen by our judges. Every research was accomplished in the Ability of Dentistry of Piracicaba - UNICAMP. Reached its term, this work of scientific research allowed to end that the use of the exams for the antigens eritrocitários and even of the antigens leucocitários, it just took at a level of absolute credibility when they excluded the paternity accused; that the exams of DNA offer an index of certainty of 99,99% in cases of investigation of paternity, that the tribunals passed the to move the thing judged material in actions that deny of paternity with requests based on exams of DNA and that the expert, having been worth of the limits taxes for the available technique in each time, it could not be made responsible by the reform of the sentence in action that deny of paternity, with base in the exam of DNA

Resumo: Na Polícia Militar do Estado de São Paulo (PMESP) o registro das condições bucais de seus elementos, para fins de identificação, é feito por meio do preenchimento de fichas odontolegais padronizadas. O preenchimento das referidas fichas é feito com um grande grau de subjetividade em virtude da falta de calibragem dos cirurgiões-dentistas associada às diferentes realidades enfrentadas por cada um deles nos diversos batalhões espalhados pelo estado, podendo, no futuro, causar eventuais erros ou gerar dificuldades quando necessário seu uso em casos práticos. A fim de melhorar a qualidade dos dados arquivados foi proposto o acréscimo de radiografias periapicais da região de pré-molares superiores, obtidas com o auxílio de posicionadores de radiografias, e fotografias frontais dos elementos da corporação, com posicionamento padronizado de cabeça, com sorriso forçado e com oclusão em máxima intercuspidação habitual. Para realizar este estudo, foram feitas simulações com 31 crânios secos, sem distinção de gênero e com idade entre 10 e 50 anos, que serviram de objeto de pesquisa para a obtenção de: fichas odontolegais no padrão da PMESP, preenchidas por estudantes dos 3º e 4º anos de graduação de Odontologia da FOP/UNICAMP; radiografias periapicais de pré-molares superiores; e fotografias frontais, as quais posteriormente foram encaminhadas para estudantes do curso de extensão em odontologia legal e deontologia da FOP/UNICAMP, para que fizessem a identificação dos crânios pelos documentos elaborados pelo 1° grupo. Feita a dentificação, os examinadores declararam quais as dificuldades encontradas e quais os métodos que permitiram uma identificação mais rápida ou mais fácil (a ficha odontolegal, as radiografias periapicais ou a fotografia frontal). Para complementar a avaliação subjetiva dos examinadores foi feita uma avaliação objetiva pelos pesquisadores pelo registro do tempo gasto pelos primeiros para a realização das identificações em cada método de identificação (ficha, radiografia e foto). Ao final, concluímos que o acréscimo dos registros radiográfico e fotográfico confere maior objetividade às fichas odontolegais da PMESP, tornando o processo de identificação mais prático e confiável
Abstract: At São Paulo State Military Police (PMESP), bucal conditions records of its elements, in order to identify them, it is done through fulfilling standard odontological cards. The process of fulfilling the cards is done with a great degree of subjectivity in view dentist's miscalibration, associated to different realities faced to each one of them in the various battalions dispersed through the state, being possible, in the future, to cause eventuals mistakes or create difficulties when its use in operative cases be needed. In order to improve the quality of the data recorded we propose the raise of periapicals x-rays photographs of the upper pre-molar region, taken with the assistance of radiography positioners and frontal view photographs of the elements of the corporation, with standardized head position, with forced induced smile and with maximum habital intercuspidation occlusion. In order to realize this study, 31 simulations were done with dry skulls, no gender distinction and aged from 10 to 50 years old, that was used research material to obtain: odontological records at PMESP standard, fulfilled by 6th. and 8th. Period under graduate students of odontology, from FOP/UNICAMP; upper periapicals pre-molar, x-rays photographs and front view photos, which will be later guided to students of the FOP/UNICAMP Forensic Odontology and Deontology extension, in order to perform the identification of the skulls through the elaborated records by the first group. Once perfomed the identification, the examiners declared the difficulties found and which methods allowed them to a faster or easier identification (the odontological record, the periapicals x-rays photographs or the front view photographs). In order to complement the subjective avaliation by the examiners, an objective avaliation was performed by the investigators through the record of the spent time by the first ones to perform the identifications by each method of identification (record, x-ray photograph and photograph). Finally we concluded that the addition of photographic and radiographic records, confer greater objectivity to PMESP odontolegal records, turning the identification process more practical and confident

Full textSometimes the process of human identification faces situations that little of the human body remains to be investigated, in these cases all identificatory methods available must be employed. The aim of this study was to obtain data to facilitate the understanding of the Carrea`s study 9 about stature as well as check the possibility of estimating final stature using the mathematical calculations developed by Carrea using two different methodologies. Stature measurement was perfomed in 46 Brazilian from Curitiba - PR aged between 22 and 37 years and divided into three groups: Group 1 consisted of 24 subjects without orthodontic treatment and with the six mandibular anterior teeth aligned, Group 2A consists of 22 subjects with crowding of the mandibular anterior teeth before orthodontic treatment and Group 2B comprised the same 22 subjects of the Group 2A, but after orthodontic treatment and with the mandibular anterior teeth aligned. The first methodology evaluated, which was called index of Carrea (1) used the mathematical formulas developed by this author in which the radius-chord and arch measurements were obtained directly from the digitalized orthodontic models. In the second method, index of Carrea (2), the arch was measured on the digitalized orthodontic models, but the radius-chord was obtained dividing the arch measurement by a numeric constant (1.0472) observed in the table of progressive proportion described by Carrea 9. Carrea index (2) was applied in all subjects of the sample without separating them in groups, since the radius-chord was calculated from the measured arch regardless of the disposition of the lowe anterior teeth. The descriptive analysis of the percentage of subjects with real stature within the range of statures estimated applying the index Carrea (1) performed as follows: Group 1 - 41.7%, Group 2A - 72.3% and Group 2B - 54.5%. The study of the size range of the statures estimated presented the following result: 18.9 cm for the Group 1, 30.6 cm for the Group 2A and 15.4 cm for the Group 2B. Using the index Carrea (2) it was found that 15.2% of the sample had their real 9 stature within the range of the statures estimated and the size of this range was 8 cm. It was concluded that the indexes of Carrea (1) and (2) have no applicability as a method to estimate the final stature. Its not confirmed at least explicitly in the studies of Carrea that was his aim to estimate the stature. It was observed that Carrea intended to calculate the final human stature proportional to the sum of mesio-distal dimensions of lower central incisor, lower lateral incisor and lower canine ipsilateral.

Resumo: O prontuário odontológico é um documento de grande importância na Odontologia e, quando bem elaborado torna-se um grande aliado do Cirurgião-Dentista, servindo como prova em qualquer época. Tem ainda função de identificação humana em indivíduos onde os meios mais comuns de identificação não podem ser utilizados. No entanto, o tempo de guarda do prontuário odontológico não possui uma definição padronizada e até mesmo nossa legislação mostra-se confusa sobre referido assunto. A presente pesquisa buscou relacionar quais são os principais componentes do prontuário odontológico dos profissionais participantes, qual a forma de coleta dos dados anamnéticos, quem os realiza e onde os mesmos são arquivados, além de determinar o grau de conhecimento dos Cirurgiões- Dentistas da cidade de Assis-SP sobre o tempo de guarda do prontuário odontológico e analisar as leis vigentes sobre o referido assunto e os aspectos éticos e legais pertinentes. Para a presente pesquisa foram distribuídos questionários com questões estruturadas e abertas sobre o prontuário odontológico para todos os Cirurgiões-Dentistas cadastrados na Prefeitura Municipal da cidade de Assis ¿ SP, num total de 121. Após análise dos dados pode-se concluir que os prontuários odontológicos dos profissionais participantes são compostos em sua maioria de tomadas radiográficas, fichas de anamnese, modelos de gessos e plano de tratamento, dentre outros documentos componentes, e que 40% dos Cirurgiões-Dentistas utilizam o sistema de folhas elaboradas por eles e impressas em gráfica para a coleta de dados anamnéticos, sendo 88% preenchidas pelos próprios profissionais, e 59% arquivadas em armário de aço. Observa-se também que os Cirurgiões-Dentistas da cidade de Assis-SP não apresentaram conhecimento definido sobre o tempo de guarda do prontuário odontológico, já que 47% acreditam que o tempo de guarda é de 20 anos, data não encontrada na legislação vigente. Verificou-se também que não há na legislação consultada um tempo de guarda definido do prontuário odontológico aplicável a todos os casos, pois se trata de tema ainda não pacificado. Conclui-se que dentre os tempos de guarda citados em toda a literatura o que mais se adeqüa a realidade da clínica odontológica é o proposto pelo Código de Defesa do Consumidor, ou seja, cinco anos a contar da data do conhecimento da existência do dano, ou seja, indefinidamente
Abstract: The handbook dentistry is a document of great importance inside of the Dentistry and, when elaborated can become a great ally of the Dentist, serving as proof in any time. The handbook has still function of human identification in individuals where the most common ways of identification they cannot be used. However, the time of guard of the handbook dentistry is a subject that still doesn't have a definition standardized and even our legislation it is shown confused on referred subject. The present research looked for to determine the degree of knowledge of the Dentist of the city of Assis-SP of the handbook dentistry, time of guard and to analyze the effective laws on him referred subject and the ethical and legal pertinent aspects. For present research it was distributed questionnaires with structured subjects and open on the handbook dentistry for all (121, hundred and twenty-one) the Dentist registered at the municipal City hall of the Municipal District of Assis-SP. After analysis of the data it can be ended that the handbook dentistry of the participant professionals they are composed in majority of RXs, anamnesis records, models and treatment plan, among other component documents and 40% of the Surgeon-dentists uses the system of leaves elaborated for them and printed by graph for the collection of given anamnetics, being 88% filled out by the own professionals and 59% filing the handbook in closet of steel. It is also observed that the Dentist of the city of Assis-SP presented deficient knowledge with respect to the time of guard of the handbook dentistry, since 47% believe that guard's time is of 20 years, it not dates found in the current law. It was also verified that no there is in the consulted legislation a time of guard defined of the handbook applicable dentistry the all of the cases, because it treats with theme which still no pacified. It is ended that among the times of guard mentioned in the whole literature that more the reality of the is adapted Dentistry is it proposed by the Code of Defense of the Consumer, five years to count of the date of the knowledge of the existence of the damage, or be, indefinitely

Full textForensic facial reconstruction is a technique that has the aim of recognition and identification, in situations in which a known identity of the sketelon submetted to medico-legal procedures is not available. The objective of the study was to study the soft tissue thicknesses that cover the face of autopsied corpses that were sent to Guarulho´s Medical-Legal Institute from September 2010 to September 2011. Measurements of 49 anatomic references were performed in the face of corpses with less than 24 hours of death; data were analysed using t test with bicaudal p. The project was approved by the University of São Paulo´s School of Dentistry Ethics Committee (protocol number 144/2010). One hundred corpses were studied, being 64 male and 26 female. They were mainly 41 to 60 years old. Among all the 49 studied anatomic references, just five presented a p value lower than 0.05, that is, these references showed differences between sex: upper lip margin (p=0.006), superior labius sulcus (p=0.006), stomion (p=0,001), right lateral orbits (p=0.008) and left chelion (p=0.009). The studied anatomic references allowed to establish more precise parameters of the faces thicknesses that can be applied in corpses facial reconstructions in the Brazilian population, and some anatomic references presented a higher discriminant Power with regard to sex. Furthermore, the anatomic landmarks offered information to a reference table with the objective of forensic facial reconstruction.

Full textFace is the body part that most synthesizes the human being and, to be understood, has been targeted from different branches of science, including the Forensic Facial Identification area. The Cephalometry, science responsible for facial studies and their relationships, although extensively studied for clinical and radiographic employment, especially by dental professionals, it has not been standardized and validated yet for its use in facial images and/or photo analysis. Due to the growth of technology and automated production of the era in which we live, where camera-coupled devices are part of vast majority ordinary life of world population, methodologies development is necessary to confirm the objectivity, reproducibility and reliability of their analyzes, especially for areas that require precision and technical/scientific rigor as criminal expertise. In this sense, this research aimed to propose a standardization method in determining cephalometric points exclusively based on frontal view facial images and determine which points have higher and lower variability of measurement, for possible use in human identification. The experimental part of the study was drawn in two stages. In the first phase, the conventional method (classic cephalometry) was used to describe the reference anatomical points and, in the second, the proposed photoanthropometric method was used. Both phases were analyzed by five examiners who scored 16 points in facial topography of 18 images randomly chosen from an image database. For all analyzes, a software developed by the Expertise Service in Audiovisual and Electronics of the National Institute of Criminology, Federal Police, called SMVFace, was used. It could be observed that there was a large variability reduction of anatomical points after the photoanthropometry description adoption, especially for 15 Alar, Endocanthion, Glabella, Gonion, Iridium Medial, Upper Lip and Zigion points. In contrast, a slight variability increase of Chelion, Lower Lip and Gnathion points was observed. Despite the increased variability of these points, most markings are performed below the acceptable error advocated by some studies. These results demonstrate that, although some limitations, the use of the proposed photoanthropometric description was crucial to achieve greater accuracy of anatomical landmarks determination in general

Full textForensic anthropology is the application of the physical anthropology science and human osteology in criminal cases where the victim\'s remains are in an advanced stage of decomposition. Due to migration Brazilian population is very diverse, comprising many races and ethnic groups, therefore it is much more varied than the Scottish population, which tends to be more homogenous once there was significant immigration to Scotland from the rest of the United Kingdom. The present study aimed to compare the craniometric variations of two populations (Brazilian and Scottish), and analyze the reliability of sex determination in the two populations for forensic purpose. The total sample was comprised of 200 skulls and 136 mandibles, the Brazilian sample consisted of 100 complete skulls and the Scottish sample was composed of 100 skulls and 36 mandibles, both of which are documented samples. The measure\'s protocol comprised 72 measurements, being 51 cranial and 21 mandibular. The results showed that the Scottish sample had a larger mean compared to the Brazilian sample in 54 variables of the 72 measures. Among the cranial measurements analyzed, 33 variables showed a significant difference between the two samples and among the 21 mandibular measurements considered, 05 presented a variation greater than 20%, 09 between 10% and 20%, 07 lower than 10%. The most dimorphic measurements for both samples were the bizigomatic width (73% of accuracy for the Brazilian sample and 77% for the Scottish sample), the bigoniac width (79% and 83,30%), the Porion-Mastoidale length (76% and 75%), and the left side mandibular body height (67 and 80,60%). The multivariate discriminant analysis showed satisfactory results for the Brazilian sample with a percentage of accuracy varying between 76-90% and in the Scottish sample 81-86.6%. Through the analysis of the ROC curve, four reference tables were developed: 01 for Brazilian cranial measurements, 01 Brazilian mandibular measurements, 01 Scottish cranial measurements and 01 Scottish mandibular measurements The present study showed a difference between the two samples studied, but it is not possible to define an unique cause responsible for that because this comprise multifactorial aspects. The quantitative methodology analyzed showed sexual dimorphism in both samples.

Resumo: A identificação humana pode ser realizada por meio dos mais variados procedimentos técnicos, principalmente pela análise comparativa dos documentos do prontuário odontológico. Atualmente, as técnicas de biologia molecular têm se apresentado como o recurso comparativo mais eficaz, contudo parcela significativa desses métodos requer, além do estabelecimento prévio de parâmetros de coleta de material biológico, a verificação da freqüência alélica da população na qual será aplicada. Assim, o presente estudo procurou evidenciar a freqüência dos alelos em 3 lócus de STR do cromossomo Y (DYS390, DYS391 e DYS393) numa população de indivíduos brasileiros leucodérmicos. Para tanto, foram padronizados protocolos de coleta e armazenamento de diferentes materiais biológicos, e estabelecidas rotinas de extração e amplificação do DNA. Os resultados apresentaram o lócus DYS390 com freqüência nos alei os 21, 22, 23, 24, 25 e 26, sendo o alelo 24 o que apresentou maior freqüência desse lócus, com 46%; o STR DYS391 com presença nos alelos 8,9, 10, 11 12 e 13, tendo o alelo 11 incidência de 37% desse STR; e o STR DYS393 nos alelos 11, 12, 13 14 e 15, tendo o alelo 13 apresentado freqüência de 45% desse lócus. Esses dados, comparados àqueles de outras populações, demonstraram haver individualidade no perfil alélico da população estudada, comprovando que, mais do que aplicar as metodologias disponíveis, é prudente que se verifiquem os padrões dos alelos na população alvo, pois a utilização de padrões alélicos de populações diversas da nossa pode levar a imprecisões nos diagnósticos de identificação humana
Abstract: Human identification can be accomplished by several technical procedures, especially by the comparative analysis of dental documents. Nowadays, molecular biology introduced more effective resources for the human identification. However, these methods demand the previous definition of parameters to the collection of biological material, and the verification of the allele frequency of the population in which they will be applied. Aiming to subsidize these methods, we observed the frequency of the alleles in three loci of STRs of the Y chromosome (DYS390, DYS391 and DYS393) in a group of Brazilian white subjects. We also standardized protocols for the collection and storage of different biological materiais, besides defining routines for the extraction and amplification of the DNA. Results presented alleles 21, 22, 23, 24, 25 and 26 in the locus DYS390, being the allele 24 the most frequent with 46%. STR DYS391 presented alleles 8, 9, 10, 11 12 and 13, and the allele 11, with 37%, was the most frequent. STR DYS393 presented alleles 11, 12, 1314 and 15, and the allele 13, with 45%, was the mostfrequent. The comparative analysis of these data, with information related to other populations, stresses the singularity of the allele profile of the studied population. Therefore, prior to the introduction of recent methods of molecular biology to the human identification, we should carefully verify allele patterns of the population, because the use of allele standards of other populations could produce imprecision in human identification processes

Full textResumo: Na sociedade, a identificação humana é indispensável tanto por razões legais como humanitárias. Porém, existem situações em que corpos encontrados não são passíveis de reconhecimento ou quando não há suspeição, impossibilitando a identificação. Nesses casos, análises antropológicas são de extrema importância, pois permitem estabelecer o perfil biológico do sujeito. Assim, realiza-se a Reconstrução Facial Forense (RFF) para possibilitar o reconhecimento e levar a uma possível identificação. A RFF, para ser realizada, precisa dos valores das espessuras de tecidos moles faciais (ETMF) em diversos pontos craniométricos. Essas medidas servem como guia para se estabelecer um limiar do contorno da face e podem ser influenciadas por diferentes fatores como sexo, ancestralidade, idade e índice de massa corporal (IMC). Não há na literatura tabelas de ETMFs de crianças e adolescentes brasileiros, para auxiliarem na RFF. O objetivo desse trabalho foi realizar a mensuração da espessura de tecidos moles de crianças e adolescentes brasileiros, a partir de dados de imagens de Tomografias Computadorizadas de Feixe Cônico (TCFC) de indivíduos vivos, considerando-se as variáveis sexo, idade, cor da pele e índice de massa corporal. Neste estudo, foram mensurados os 21 pontos craniométricos pré- determinados por meio do software Osírix Lite, de imagens de TCFC da região de cabeça e pescoço de 103 não adultos brasileiros (39 crianças e 64 adolescentes), obtidas junto aos arquivos de imagens de uma...

Abstract: In society, human identification is indispensable both for legal and humanitarian reasons. However, there are situations in which bodies found are not recognizable or when there is no suspicion, making identification impossible. In these cases, anthropological analyzes are extremely important, since they allow to establish the biological profile of the subject. Thus, Forensic Facial Reconstruction (FFR) is performed to enable recognition and lead to a possible identification. The RFF, to be performed, needs the values of facial soft tissue thicknesses (FSTT) at several craniometric points. These measures serve as a guide to establish a threshold of the face contour and can be influenced by different factors such as sex, ancestry, age and body mass index (BMI). There are no tables in the literature of FSTTs of Brazilian children and adolescents, to assist in FFR. The objective of this study was to measure the thickness of soft tissues of Brazilian children and adolescents, based on data from Cone-Beam Computed Tomography (CBCT) images of living individuals, considering the variables gender, age, skin color and body mass index. In this study, 21 pre-determined craniometric points were measured using the Osírix Lite software, from head and neck CBCT images of 103 non-Brazilian adults (39 children and 64 adolescents), obtained from the image files of a Clinic of Radiology and Dental Documentation located in the city of Araraquara - SP.

Jà DENTADURA à estÃtico, pois define somente uma determinada fase da vida do indivÃduo: à o conjunto dos dentes naquele momento. Neste Ãltimo caso, na perÃcia para estimativa de idade examina-se a dentadura do indivÃduo naquele momento. O desenvolvimento da radiologia odontolÃgica introduziu novos mÃtodos à estimativa de idade, que aumentaram o grau de confianÃa da mesma. A inspeÃÃo direta dos dentes à o mÃtodo atualmente utilizado para realizar a estimativa da idade cronolÃgica dos indivÃduos no IML â Fortaleza. Este estudo concluiu que tais procedimentos necessitam ser complementados por exames radiolÃgicos para que os resultados sejam mais fidedignos, os quais irÃo propiciar a determinaÃÃo da idade cronolÃgica dos indivÃduos com maior acurÃcia.
The estimation of chronological age can be defined as the process that evaluates the stage of evolution or involution of a body. The age determination by a dental evaluation is a technical inspection that can be performed by a Surgeon-Dentist, in accordance with the law of dentistry practice. This examination is carried through in legal medicine institutes with high frequency. In the Institute of Legal Medicine (IML) of Fortaleza - CearÃ, this percentage is 32.4% of all examinations. This study aimed to analyze the procedures for estimation of chronological age by dental evaluation conducted in IML of Fortaleza, based on procedures and methods for estimating the chronological age as described in literature. A literature review was performed and it has demonstrated that the estimation of chronological age has different nuances, it has been studied for a long time, and there are methods with accurate results that are required in many policy and judicial court processes. The most important information for age determination by examination of permanent teeth is distributed in their evolution stages: mineralization, dental eruption and dental late alterations. The technical term DENTITION has a dynamic sense, since it defines several stages from the thickening of the epithelium of the basal layer to the dental loss. DENTURE is static, as it defines only a phase of life of the individual: it is all the teeth at that time. The development of dental radiology has introduced new methods for estimating age, which increased the age determination accuracy. The oral examination is the only method currently used to age determination in the IML - Fortaleza. This study concluded that the oral examination procedures need to be complemented by radiological examinations that show reliable results and accurate age determination.

Resumo: A violência interpessoal urbana representa um sério desafio para autoridades e gestores públicos. Este estudo investigou o trauma buco-maxilo-facial decorrente de violência interpessoal quanto à epidemiologia e implicações criminais, bem como avaliou a importância da documentação clínica nos exames de corpo de delito. Foi realizado estudo observacional retrospectivo envolvendo 1.048 relatórios odontológicos de corpo de delito gerados nos anos de 2012 e 2013, na cidade do Rio de Janeiro, RJ, Brasil. Violência interpessoal foi causa de trauma buco-maxilo-facial em 405 (38,6%) exames, envolvendo principalmente homens jovens, brancos e solteiros. O agente lesivo mais comum foi o soco. Os tecidos moles foram os mais lesionados, sendo a equimose a lesão prevalente. Os ossos mais fraturados foram maxila e mandíbula. Os dentes anteriores mostraram maior incidência de fraturas coronárias. Quanto à classificação penal, predominou o dano corporal leve, sendo que as lesões somente aos dentes implicaram dano leve, grave e gravíssimo. Houve apresentação de documentação clínica em 132 (32,6%) exames periciais. O trauma buco-maxilo-facial decorrente de violência interpessoal alcançou níveis preocupantes nos dois anos do estudo, representando a documentação clínica importante meio de prova particularmente nos exames de corpo de delito indireto. Sugere-se a realização de estudos epidemiológicos periódicos, que abranjam as demais regiões do Estado do Rio de Janeiro e do país para análise mais completa do fenômeno, bem como a participação do cirurgião-dentista como membro efetivo das equipes forenses
Abstract: The urban interpersonal violence represents a serious challenge for public authorities and managers. This study aimed to investigate the oral maxillofacial trauma caused by interpersonal violence regarding its epidemiologic and criminal implication aspects, as well as to evaluate the importance of clinical documentation in forensic exams. A retrospective observational study has been conducted involving 1,048 forensic dental reports generated in the years 2012 and 2013 in the city of Rio de Janeiro, RJ, Brazil. Interpersonal violence was the cause of oral maxillofacial trauma in 405 (38.6%) exams, involving mainly young, white and unmarried men. The most common harmful agent was the punch. The soft tissues were most injured, being bruise the predominant injury. The more fractured bones were maxilla and mandible. Anterior teeth showed a higher incidence of crown fractures. Regarding criminal classification, light body damage predominated and teeth-only injuries implied light, severe and very severe damage. There was presentation of clinical documentation in 132 (32.6%) forensic exams. It was found that the oral maxillofacial trauma due to interpersonal violence has reached alarming levels in both years of study, being the clinical documentation an important mean of obtaining evidence, particularly in indirect forensic examination. It is suggested to carry out epidemiological studies covering other regions of the State of Rio de Janeiro and the country for more detailed analysis of the phenomenon, as well as the participation of the dentist as an effective forensic team member

Full textFor legal reasons, the human body identification is an important contribution of forensic dentistry to society. In order to identify a copse, there are many techniques and factors that must be clarified, such as age, sex and race. Sex determination by dentistry parameters have been largely used in human identification and, in this knowledge area, the measure of teeth is an important technique that can be applied. For that reason, it is important to establish a pattern of tooth measure for specific populations. In this context, the aim of this study is to verify the sexual dimorphism in Brazilian adults by tooth measurement. The sample used plaster models from 200 subjects of both sexes, aged 20 to 30 years old. The measures used were the mesiodistal (MO) and buccolingual (VL), using the dimensions of ali teeth, except third molars. These mensuration was performed directly on the plaster models, using a Digital Caliper-rule from Digimess ® brand, with needled tip, and measurement in millimeters, with an error margin of 0.01mm. For statistical analysis we used the STATA 12.0 software. To test the reliability of the technique it was used the Intra Class Coefficient for Intra and Inter Examiner data. To exhibit the sample, descriptive statistic was used (mean, standard deviation, and minimum and maximum values). For comparison between homologous teeth and sex, it was used the Student-T test. The data analysis used was the logistic regression and a moire was created according to the best precision from the technique. Three techniques were performed to check the sexual dimorphism, Logistic Regression, Linear Discriminant Function and Discriminant Function KNN. The significance levei for ali tests was 5%. The study population was composed of 200 research participants. Of those, 100 were male and 100 were female. The age average was 24.33 years old and the height average was of 1.69 meters. According to the results presented in this study we can conclude that it is possible to check the sexual dimorphism in Brazilian adults through dental measures and we can say that no differences between homologous teeth was seen; dental elements from male participants had higher averages than those from female participants. The best indexes to evaluate sexual dimorphism were the measures of the canines and molars teeth. Multivariate techniques were more accurate and KNN Oiscriminant Analysis showed the best results.

Resumo: Com o passar dos anos tem se constatado um aumento da violência, e como conseqüência, do número de exames de corpo de delito envolvendo a face e cavidade bucal. Mesmo existindo coeficientes dos índices estético, mastigatório e fonético, nota-se uma evidente falta de padronização na avaliação e enquadramento das lesões dentárias de acordo com o artigo 129 do Código Penal. Devido a este fato o presente estudo avaliou a maneira como os juízes, peritos dos Institutos Médico Legais (IMLs), entre eles médicos e cirurgiões dentistas, e especialistas em Odontologia Legal, tipificam as lesões dentárias; assim como comparou as convergências e divergências das opiniões desses profissionais e discutiu os aspectos éticos e legais pertinentes ao tema. Nesse objetivo, foi confeccionado um questionário com questões estruturadas, que foi entregue aos voluntários, juntamente com duas cópias do termo de consentimento livre e esclarecido (TCLE). O projeto da presente pesquisa foi aprovado pelo Comitê de Ética em Pesquisa sob o protocolo nº 076/2009. A amostra foi de 82 profissionais, atuantes nos Estados de São Paulo, Rio de Janeiro e Mato Grosso, que qualificaram supostas lesões dentárias de acordo com o artigo 129 do Código Penal. Conclui-se que apesar da existência de uma tendência à convergência nas opiniões dos profissionais, quando observadas as porcentagens maiores, existe uma oscilação na interpretação das questões, fato que dificulta a aplicação de um critério único. Pelo contrário, se existissem parâmetros para tal fim, diminuiriam as possibilidades de variações na forma de interpretação entre profissionais diretamente ligados no processo, no tocante aos danos sofridos pela vítima
Abstract: Through the years, it has been noticed an increase of violence and forensic examination cases related to the face and oral cavity. Although there are aesthetic, phonetic and masticatory indexes, there is an obvious lack of criteria for the assessment and classification of dental injuries in accordance to 129th Article of the Penal Code. Due to this fact, this study analyzed how judges, medical and dental forensic experts, and specialists in forensic dentistry typify the dental injuries, as well as checked the convergence and divergence of opinions of these professionals and discussed the ethical and legal issues referred to this topic. In this goal, it was made a questionnaire with structured questions, which was delivered to the volunteers, along two copies of the informed consent (IC). The project of this research was approved by the Research Ethics Committee (protocol nº 076/2009). The sample consisted of 82 professionals from the States of São Paulo, Rio de Janeiro and Mato Grosso, that qualified supposed dental injuries in accordance with 129th Article of the Penal Code. It was concluded that despite of the existence of a convergent tendency in the points of view of professionals, while observing the highest percentages, there are discrepancies in the interpretation of the questions, that difficult the application of a single criterion. Although, if there was a parameter for this purpose, it would minimize the possibility of different interpretations among the professionals directly involved in the process, when related to the damages suffered by the victim
