With an aging population and with the number of patients with large prosthetic joints increasing, the recommendation of antibiotic use in this specific population has generated significant discussion. Dentists often treat patients with large prosthetic joints; however, little is known regarding the prescribing practices of dental providers. This cross-sectional study carried out in the State of Iowa, United States, evaluated whether dentists were familiar, followed, and were satisfied with the 2015 American Dental Association Clinical Guidelines and the 2016 American Academy of Orthopaedic Surgeons Appropriate Use Criteria (AUC), and whether dentists responses were associated with demographic and provider characteristics. Dentists’ concerns about antibiotic resistance, medical legal aspects, and adverse effects related to using antibiotic prophylaxis were also examined. Of the 1521 surveys that were sent by mail, a total of 635 were returned, for a response rate of 41.7%. Our results confirm that dental practitioners were very concerned about antibiotic resistance (43.9%) compared to 5.23% who were not at all concerned. In addition, female subjects were significantly more likely to be very concerned about antibiotic resistance than were male subjects (50.9% vs 41.4%; p=0.0376). Moreover, subjects that practiced in urban areas were more likely to be very concerned about antibiotic resistance that those practicing in rural areas (47.9%vs 37.5%; p=0.0157). We also observed that for a healthy patient, 28.9% of dentists would never recommend antibiotics. On the other hand, 44.9% of the respondents would recommend antibiotic premedication within the first 2 years since prosthetic joint replacement, 14.1% would recommend it within the first year, and 6.9% would recommend it for life. Dentists were aware of the lack of effectiveness of antibiotic prophylaxis in preventing prosthetic joint infection. However, premedication recommendations by physicians and patient preferences influenced dentist’s prescribing practices. Overall, dentists’ recommendations for the use of antibiotic for patients with prosthetic joints undergoing dental procedures varied depending on the health status of the patient, the dental procedure to be performed, the time since joint surgery, physician’s recommendations and patients preferences.

Resumo: A cerâmica é uma opção que preenche as exigências estéticas, biológicas, mecânicas e funcionais de um material restaurador. O sistema CAD/CAM empregado na Odontologia permite confeccionar restaurações indiretas, em um curto período de tempo, cimentá-las na mesma sessão clínica, sem a intermediação do laboratório de prótese. Qualquer material restaurador está sujeito a desgastes por ação da mastigação e a escovação diária. Protocolos de higienização profissional devem ser estabelecidos de maneira a não afetarem a rugosidade superficial das restaurações. O objetivo deste estudo foi avaliar a rugosidade superficial (Ra) de materiais restauradores CAD/CAM após diferentes métodos de higienização. Trata-se de um estudo in vitro que utilizou espécimes (n=144) dos seguintes materiais: Cerâmica Feldspática (Cerec Blocs, Dentsply Sirona); Cerâmica Feldspática reforçada por Leucita (IPS Empress CAD, Ivoclar Vivadent); Cerâmica Di-silicato de lítio (IPS e-max CAD, Ivoclar Vivadent) e Compósito nano híbrido (Grandio Blocs, Voco), sendo que dois materiais, Cerâmica Feldspática e Cerâmica Feldspática reforçada por Leucita foram avaliados com e sem glaze. Os espécimes foram submetidos a três diferentes métodos de higienização (escovação simulada; jato de bicarbonato de sódio e profilaxia com taça de borracha e pasta profilática). A rugosidade superficial foi mensurada antes e após os diferentes métodos de higienização por meio do rugosímetro de contato. A análise de variância foi feita para ...

Abstract: Dental ceramic has been a restorative material option that may provide the aesthetic, biological, mechanical and functional requirements. CAD/CAM (computer aided design/computer aided manufacturing) system used in Dentistry allows to perform indirect restorations in a short period of time and proceed the cementation in the same clinical session without the intermediation of prosthesis laboratory. However, any restorative material can wear due to chewing and daily toothbrushing action. Thus, hygiene protocols should be stated in order to not affect the surface roughness of restorations. This study aimed to evaluate the surface roughness (Ra) of CAD/CAM restorative materials after different hygiene protocols. This in vitro study used the following materials (n=144): Feldspathic ceramic (Cerec Blocs, Dentsply Sirona); Leucite-reinforced feldspathic ceramic (IPS Empress CAD, Ivoclar Vivadent); Lithium disilicate ceramic (IPS e-max CAD, Ivoclar Vivadent) and Nanohybrid resin-based composite (Grandio Blocs, Voco). For Feldspathic ceramic and Leucite-reinforced feldspathic ceramic it was performed the evaluations with and without glaze. The samples were submitted to three different hygiene protocols (simulated brushing, sodium bicarbonate jet and prophylaxis with rubber cup and prophylactic paste). Surface roughness was measured before and after the hygiene protocols by a contact rugosimeter. ANOVA test was applied to evaluate the initial roughness among materials, followed by Games...

O objetivo deste estudo foi avaliar o possível efeito da saliva in situ, associada ou não ao flúor, sobre a recuperação da estrutura dentária do esmalte desmineralizado, que recebeu profilaxia utilizando jato de bicarbonato de sódio. Para isso, foram utilizados 40 blocos de esmalte de dente bovino de 4x4 mm, os quais foram submetidos a um processo de desmineralização in vitro para a formação de lesões artificiais de cárie. Sobre a superfície destes blocos, foi aplicado o jato de bicarbonato de sódio, simulando a realização de uma profilaxia profissional. Após essa etapa, os blocos foram divididos em dois grupos (GI e GII) e montados em dispositivos intra-bucais, os quais foram utilizados por 10 voluntários, durante dois períodos experimentais de quatro horas. Os blocos do GI foram expostos diretamente à saliva in situ, enquanto os do GII, foram expostos à saliva associada ao flúor sob forma de bochecho com solução de NaF a 0,2%, durante o minuto inicial. No primeiro período experimental, metade dos voluntários fez parte do GI e a outra metade do GII, havendo uma inversão dos grupos no segundo período. As possíveis alterações ocorridas na superfície do esmalte após as etapas do experimento, foram avaliadas através de testes de microdureza Knoop (25g/5s) e da quantificação do desgaste com o auxílio de um rugosímetro. Para a comparação dos valores de microdureza e de desgaste entre os grupos, e entre as etapas de cada grupo, foi aplicada a Análise de Variância a dois Critérios (ANOVA) e o teste de Tukey, adotando-se um nível de significância de 5% (p<0,05). Os resultados do teste de microdureza mostraram uma diminuição, estatisticamente significante, nos valores de microdureza superficial do esmalte após a etapa de desmineralização (183,7KHN), quando comparada à microdureza superficial inicial (342KHN). Em seguida, após a simulação da profilaxia, houve um aumento significante da microdureza (337,3KHN), não havendo diferença estatisticamente significante entre o valor inicial. Quanto ao desgaste, a simulação da profilaxia promoveu um desgaste no esmalte desmineralizado da ordem de 0,709µm. Após a etapa de remineralização, o valor da microdureza diminuiu um pouco em relação ao valor inicial (303,7KHN), embora tenha sido próximo ao mesmo. Em relação ao valor do desgaste, foi observada uma diminuição estatisticamente significante (0,476 µm), o que representa uma diminuição de quase um terço do valor inicial. Não houve diferença estatisticamente significante entre os resultados dos grupos I e II em todas as etapas do experimento. De acordo com as condições e com a metodologia adotadas na presente pesquisa, foi possível concluir que após 4 horas de remineralização in situ houve recuperação de parte da estrutura dentária perdida devido à aplicação do jato de bicarbonato de sódio sobre o esmalte desmineralizado, apesar de a realização de um bochecho adicional com solução fluoretada não ter promovido aumento no ganho mineral em relação à ação somente da saliva.
The aim of this study was to evaluate the effect of saliva in situ, in the recovery of the superficial structure of the demineralized tooth enamel in which a sodium bicarbonate jet was applied. The effect of an additional mouthrinsing with a NaF solution was also evaluated. A total of 40 specimens of bovine enamel (4x4 mm) were processed in vitro to obtain artificial caries lesions were utilized for this study. A jet of sodium bicarbonate was applied on the surface of the specimens simulating a prophylaxis procedure. The specimens were divided in two groups(GI and GII). They were mounted in an intra-oral model used by 10 volunteers for two fourhour experiments. During the first four-hour experiment, the specimens of GI were directly exposed to saliva in situ. Those of GII were exposed to one minute mouthrinsing with 0.2% NaF. In the second four-hour experiment, the volunteers were crossed-over to the opposite experimental treatment group. The changes on the enamel surface were analyzed by the superficial microhardness test (Knoop, 25g/5s) and perfilometry, using a rugosimeter to determine the superficial dental wear. In order to compare the degree of microhardness and wear, among groups in the different experimental phases, the ANOVA and the Tukey test were used with an acceptable significance of 5% (p<0.05). The microhardness test showed a significant decrease of the initial value from 342 KHN to 183.7KHN after the demineralization phase. In the prophylaxis simulation, the microhardness value increased to 337 KHN, while a 0.709 µm wear was detected. After the remineralization procedure, there was a mild decrease on the degree of superficial microhardness to 303.7 KHN. Considering the superficial wear, it was detected a significant decrease (0.476 µm) comparing to the value found after the prophylaxis. There were no statistical differences between GI and GII in all phases of the experiment. After a four-hour period of an in situ remineralization, we concluded that it is possible to have a partial recovery of the dental structure, initially lost due to the use of sodium bicarbonate on the demineralized enamel. The performance of an additional mouthrinsing with fluoridate solution did not lead to an increase in the mineral gain.

Resumo: Os objetivos deste estudo "in vitro" foram: 1) avaliar o efeito da microabrasão sobre a microdureza e a rugosidade do esmalte dental bovino, bem como a ação do polimento realizado com pastas apropriadas no esmalte abrasionado; 2) avaliar o armazenamento em saliva artificial, em diferentes tempos de ação sobre a microdureza do esmalte dental bovino. Para isso, foram utilizados 144 blocos de esmalte bovino (6,0mm x 6,0mm) que constituíram os grupos: I- tratamento com ácido fosfórico a 37% e pedra pomes (n=48), II- tratamento com Opalustre (Ultradent) (n=48), III- tratamento com Whiteness RM (FGM) (n=48). Os três grupos foram divididos em três subgrupos, de acordo com os seguintes tratamentos: a) polimento com pasta diamantada; b) polimento com pasta profilática fluoretada e c) sem polimento (controle). Foram realizados ensaios de microdureza nos seguintes tempos estabelecidos: 1) inicial (antes da realização da microabrasão e polimento); 2) após a realização da microabrasão com e sem polimento; 3) após a realização da microabrasão com e sem polimento e imersão em saliva artificial por períodos de 24 horas; 4) após a realização da microabrasão com e sem polimento e imersão em saliva artificial por 7 dias. Foram realizados ensaios de rugosidade nos seguintes tempos pré-estabelecidos: 1) inicial (antes da realização da microabrasão e polimento) e final (após a realização da microabrasão com e sem polimento (controle). Os dados obtidos foram submetidos à análise estatística ANOVA "dois fatores", e teste de Tukey com significância de 5% para microdureza e rugosidade. Os resultados mostraram que a microabrasão seguida de polimento proporcionou aumento de microdureza superficial; quando não se utilizou polimento, somente os sistemas microabrasivos com ácido clorídrico e carbeto de silício apresentaram aumento da microdureza superficial; os diferentes tempos de armazenamento em saliva artificial não resultaram em aumento da microdureza superficial; os produtos utilizados para microabrasão não proporcionaram rugosidade superficial diferentes entre si; todos os sistemas microabrasivos seguidos de polimento apresentaram maior lisura superficial quando comparados aos grupos sem polimento. Baseado nos resultados obtidos, conclui-se que a microabrasão seguida de polimento, proporcionou maior dureza e maior lisura de superfície do esmalte dental. A imersão em saliva artificial por períodos de 24 horas e 7 dias, contudo, não alterou a dureza do esmalte dental.
Abstract: The objectives of this study in vitro were: 1) evaluate the effect of microabrasion on microhardness and roughness of bovine enamel and the action of polishing carried out with the appropriate pastes on abrasioned enamel, 2) evaluate the effect of storage in artificial saliva, during different times of action, on the microhardness of bovine dental enamel. For this, used 144 bovine enamel blocks (6.0 mm x 6.0 mm), forming the groups: I-treatment with 37% phosphoric acid and pumice paste (n = 48), Il-treatment with Opalustre (Ultradent) (n = 48), Ill-treatment with Whiteness RM (FGM) (n = 48). Then the three groups were divided into three subgroups, according to the following treatments: a) diamond polishing paste, b) polishing with fluoride prophylactic paste and c) without polishing (control). Tests of hardness were carried out in the following set times: 1) initial (prior to the microabrasion and polishing), 2) after microabrasion with and without polishing (control), 3) after microabrasion with and without polishing and immersion in artificial saliva for 24 hours; 4) after microabrasion with and without polishing and immersion in artificial saliva for 7 days. Tests of surface roughness were performed in the following pre-set times: 1) initial (prior to the microabrasion and polishing) and final (after the completion of microabrasion with and without polishing) (control). The obtained data were analyzed by "two factors" ANOVA and Tukey test with significance of 5% for hardness and roughness. The results showed that: microabrasion followed by polishing provided an increase of superficial microhardness; without the use of polishing, only the microabrasive systems with hydrochloric acid and silicon carbide showed increased superficial microhardness; different times of storage in artificial saliva did not result in increased microhardness; the products used for microabrasion did not provide surface roughness different from each other; all microabrasive systems followed by polishing showed a higher surface smoothness compared with the groups without polishing. Based on these results, it can be inferred that microabrasion followed by polishing provided higher hardness and better surface smoothness of the dental enamel. However, the immersion in artificial saliva for 24 hours and 7 days was not able to increase the enamel hardness.

O objetivo deste ensaio clínico foi avaliar o comportamento de dois sistemas de polimento na regularização da superfície do esmalte dental, que apresentava-se rugosa e irregular após a remoção de braquetes ortodônticos. As variáveis de resposta foram: rugosidade superficial, luminosidade, morfologia, textura e sensibilidade. Fizeram parte dessa pesquisa clínica 30 voluntários. Os fatores em estudo foram: as técnicas de poli- mento superficial em dois níveis: Técnica 1 (discos de óxido de alumínio) e Técnica 2 (produto ácido-abrasivo), e o tempo de análise em 5 níveis: T0 (baseline), T1 (imedia- tamente após os polimentos superficiais), T2 (após polimento final), T3 (7 dias após os procedimentos) e T4 (6 meses após os procedimentos). Os dados representados por escores foram analisados considerando distribuição multinomial; os dados numéricos foram analisados como medidas repetidas no tempo, a um nível de significância de 5%. Nas análises de rugosidade superficial e luminosidade, não houve diferença estatística entre as técnicas em todos os tempos analisados. Nas análises por score, dentro de cada tempo, verificou-se igualdade significativa apenas no baseline; nos demais tempos foram observadas irregularidades superficiais estatisticamente superiores para a Técnica 1. Nenhum paciente apresentou sensibilidade dental. Ambas as técnicas foram eficientes; porém a maior lisura foi adquirida quando a Técnica 2 foi utilizada.
This clinical study evaluated the behavior of two surface polishing systems in the regularization of the enamel surface, which was rough and irregular after orthodontic brackets debonding. The response variables were: surface roughness, lightness, morphology, texture and sensitivity. Thirty volunteers were part of this clinical research. The factors under study were: Surface polishing at two levels: Technique 1 (aluminum oxide disks) and Technique 2 (enamel microabrasive product); and the Time of analysis at 5 levels: T0 (after surface polishing), T1 (immediately after surface polishing), T2 (after final polishing), T3 (7 days after surface polishing) and T4 (6 months after surface polishing). The data represented by scores were analyzed considering multinomial distribution; the numerical ones were analyzed as measures repeated in time, at a significance level of 5%. In the analysis of surface roughness and lightness, there was no statistical difference between the polishing techniques at all times analyzed. In the other analyzes, within each time, significant equality was observed only in the baseline, while in the other times superficial irregularities were statistically superior for Technique 1. No patient presented dental sensitivity. Both techniques were efficient; however, the higher surface smoothness was observed on the dental enamel surface polished with the Technique 2.

Resumo: O controle da doença cárie é um dos maiores desafios na Odontologia. O controle do biofilme, de forma mecânica pelo paciente ou pelo profissional, ainda é o melhor método preventivo Este trabalho tem como objetivo a realização de um estudo in vitro da rugosidade do esmalte de dentes decíduos submetidos a quatro métodos profiláticos diferentes. Selecionamos 32 faces proximais de dentes decíduos hígidos, que foram divididos em 4 grupos. No primeiro grupo utilizamos para o polimento mistura de pedra-pomes (SSWHITE)® e água destilada e realizamos polimento utilizando taça de borracha em caneta de baixa rotação; no segundo, pasta profilática Clinpro Prophy Paste (3M)®também com taça de borracha em caneta de baixa rotação; no terceiro jato de bicarbonato de sódio (Polident) e no quarto jato de glicina Clinpro Prophy Powder(3M). Todos os procedimentos foram realizados pelo mesmo operador, que foi calibrado na busca de reprodução de situação clínica. Em cada espécime os procedimentos foram realizados durante 10 segundos com os produtos e equipamentos determinados. Após os procedimentos profiláticos os dentes foram lavados e armazenados em água destilada até o momento das leituras. As leituras para mensuração da rugosidade superficial em micrometros foram realizadas antes e após os procedimentos profiláticos por meio do Perfilômetro Óptico Wyko NT1100 INPE. Todos os grupos provocaram um aumento do valor de Rugosidade aritmética Ra, que é a rugosidade provocada por picos e vale do esmalte de dentes decíduos, sendo que o grupo 4 do (bicarbonato) que apresentou melhores resultados por apresentar menor variação em analise estatísticas, através da ferramenta teste t-Student mostrou que não houve variação de Ra inicial entre os 4 grupos
Abstract: Caries disease control is one of the greatest challenges in dentistry. The biofilm control mechanically by the patient or by the professional is still the best preventive method. This work aims to perform an in vitro study of the enamel roughness of deciduous teeth submitted to four different prophylactic methods. We selected 32 faces close to healthy deciduous teeth, which were divided into 4 groups. In the first group we used a mixture of pumice (SSWHITE) ® and distilled water polishing with rubber cup in a low rotation pen; in the second group we used Clinpro Prophy Paste (3M) ® prophylactic paste also with rubber cup in low rotation pen, in the third group the polishing with sodium bicarbonate jet (Polident) and in the fourth group with glycine jet Clinpro Prophy Powder (3M ). All procedures were performed by the same operator properly calibrated for 10 seconds with parameters controlled after the prophylactic procedures the teeth were washed and stored in distilled water until readings. The readings for measuring surface roughness in micrometers will be performed before and after the prophylactic procedures using the Wyko NT1100 INPE apparatus obtaining the Ra value. All the prophylactic methods caused an increase in the Ra value, with the bicarbonate group 4 having the best results in statistical analysis the tStudent test tool and there was no initial Ra variation among the 4 groups

UVOD Početne karijesne lezije gleđi (bele mrlje) se definišu kao područija demineralizovane gleđi, koja nastaju kao posledica neadekvatnog higijensko-dijetetskog režima. Prevencija belih mrlja je neophodna, kako bi se dobio maksimalan učinak terapije fiksnim ortodontskim aparatima. U prevenciji i terapiji belih mrlja se primenjuju preparati na bazi kazein- fosfopeptid – amorfnog kalcijum fosfata (CPP-ACP) i preparati na bazi fluorida. Ciljevi istraživanja su bili da se ispita prisustvo početnih karijesnih lezija gleđi, nakon tretmana fiksnim ortodontskim aparatima i da se istraži uspešnost terapije početnih karijesnih lezija gleđi. MATERIJAL I METODE RADA U studiju je bilo uključeno 100 pacijenata, uzrasta od 15-50 godina, kod kojih je indikovana terapija fiksnim ortodontskim aparatima na Klinici za stomatologiju Vojvodine. Pacijenti su bili podeljeni u dve grupe, eksperimentalnu (pacijenti koji su koristili preparate na bazi kazein- fosfopeptid – amorfnog kalcijum fosfata i standardne preparate za oralnu higijenu) i kontrolnu (koji su koristili samo standardne preparate za oralnu higijenu). Analizirane su fotografije pacijenata napravljene pre početka tretmana, nakon uklanjanja fiksnih ortodontskih aparata i nakon terapije početnih karijesnih lezija. Formirana je baza podataka, koja je bila korišćena za potrebe ovog istraživanja, u okviru „Onyxceph“ softverskog programa. U istraživanju se koristio upitnik, sastavljen većinom od pitanja zatvorenog tipa. REZULTATI Rezultati istraživanja pokazuju da je većina ispitanika bila ženskog pola (68%). Početne karijesne lezije su bile češće dijagnostikovane kod muškog pola. Najveći broj pacijenata je bio iz grupe mlađeg odraslog doba (42%) i adolescenata (32%). Kod 73% pacijenata, koji su prošli tretman fiksnim ortodontskim aparatima, dijagnostikovane su početne karijesne lezije zuba na kraju tretmana. Pacijenti koji su više puta u toku dana konzumirali konditorske proizvode, u toku ortodontskog tretmana, su imali najviši procenat belih mrlja (87,5%). ZAKLJUČCI Potvrđene su obe hipoteze: 1. Prevalencija početnih karijesnih lezija gleđi nakon fiksne ortodontske terapije bila je viša od 60%, kod pacijenata koji su minimum godinu dana nosili fiksni ortodontski aparat. 2. Terapija belih mrlja preparatima Tooth Mousse (CPP-ACP) je dala značajno bolje rezultate, u odnosu na grupu ispitanika koji su koristiti samo standardna sredstva za održavanje oralne higijene. Na osnovu dobijenih rezultata kliničkih istraživanja može se zaključiti da je prevalencija početnih karijesnih lezija gleđi proporcionalno veća kod pacijenata koji su imali slabiju oralnu higijenu u toku ortodontskog tretmana, u poređenju sa pacijentima koji su imali visoku svest o važnosti higijensko-dijetetskog režima. Primena Tooth Mousse pasta u tretmanu početnih karijesnih lezija gleđi od značajne je važnosti za remineralizaciju zubne gleđi. Dužina trajanja ortodontskog tretmana nije dovedena u direktnu vezu sa pojavom početnih karijesnih lezija gleđi.
INTRODUCTION The initial carious lesions (white spots) indicate an area of demineralization of enamel as a result of an inadequate hygiene-dietary regime. The prevention of white spots lesions (WSL) is necessary in order to obtain the maximum effect of the therapy with fixed orthodontic appliances. In the prevention and treatment of white spots, products based on casein-phosphopeptide-amorphous calcium phosphate (CPP-ACP) are applied as well as preparations based on fluoride. The aims of the study were to examine the presence of initial carious lesions on the surface of the tooth after treatment with fixed orthodontic appliances and to assess the success of the therapy of initial caries lesions. MATERIAL AND METHODS The study included 100 patients aged 15-50 who were treated with fixed orthodontic appliances, at the public Dentistry Clinic of Vojvodina. Patients were divided into two groups: experimental (patients who used Tooth Mousse paste and standard oral hygiene products) and control group (using only standard oral hygiene products). The photos of patients were made and analyzed in three stages of the study - before the beginning of the treatment, after the removal of fixed orthodontic appliances and after the therapy of initial caries lesions. Using the "Onyxceph" software program, the database was created, which was used for the purposes of this research. The questionnaire composed mostly of close-ended questions was used for the purpose of this survey. RESULTS The restates of this study indicated that a majority of respondents were female. (68%). The initial carious lesions were more commonly diagnosed in men. The majority of patients with WSL were in group of young adult people (42%) and adolescents (32%). In 73% of all patients who were treated with fixed orthodontic appliances, were diagnosed WSL on the end of the orthodontic treatment. Patients who consumed confectionery products several times during the day, during the orthodontic treatment, had the highest percentage of white spots lesions (87.5%). CONCLUSION Both hypotheses have been confirmed: 1.The prevalence of initial carious lesions of the tooth enamel after fixed orthodontic therapy was higher than 60% in patients who had fixed orthodontic appliances for at least a year. 2. White spot therapy with Tooth Mousse's products showed significantly better results compared to a group of subjects who only used standard oral hygiene products. On the basis of the obtained results of clinical trials, it can be concluded that the prevalence of initial caries lesions is proportionally greater in patients with lower oral hygiene during orthodontic treatment, compared to patients who had higher awareness of the importance of the hygiene-dietary regime. The use and application of Tooth Mousse paste in the treatment of initial carious lesion is vital for the re-mineralization of the enamel surface.

Estudos sobre profilaxia antibiótica em pacientes imunossuprimidos submetidos a procedimentos cruentos odontológicos são bastante escassos, no entanto já existe um consenso de que estes pacientes são sabidamente de risco para infecção de sítio cirúrgico odontológico e que, portanto, necessitam de profilaxia antibiótica. Não é definido, no entanto, o regime profilático ideal para estes pacientes. O objetivo deste estudo é comparar a duração de antibioticoprofilaxia através de dois esquemas para prevenção de infecção após procedimentos odontológicos cruentos em pacientes imunossuprimidos transplantados renais ou hepáticos e em pacientes imunossuprimidos por quimioterapia. Este ensaio clínico foi randomizado e avaliou pacientes consecutivos com neoplasia e que fizeram uso de quimioterapia anti-neoplásica no último mês e pacientes transplantados de órgãos sólidos com medicação imunossupressora anti-rejeição, que necessitavam de exodontia e/ou raspagem periodontal como tratamento odontológico. O atendimento foi realizado na Divisão de Odontologia do Hospital das Clínicas da Faculdade Medicina da Universidade de São Paulo e foram incluídos pacientes da rotina do ambulatório que atendiam aos critérios de inclusão para participarem do protocolo da pesquisa e que concordaram em participar, assinando o Termo de Consentimento Livre e Esclarecido. Os pacientes foram randomizados para um dos dois grupos de regime profilático (grupo 1 - uma cápsula de 500mg de amoxicilina duas horas antes do procedimento odontológico; grupo 2 duas cápsulas de 500mg de amoxicilina, sendo a primeira duas horas antes do procedimento e a segunda oito horas após a primeira) e realizaram exame de sangue para avaliação da cultura hematológica após a realização do procedimento, sendo acompanhados durante um mês. A amostra calculada foi de 414 pacientes, sendo 207 em cada grupo. Os dados foram analisados através do programa SPSS Windows (versão 13.0, Chicago IL) e a partir daí foi obtida uma tabela descritiva e utilizado o teste qui-quadrado para comparação das variáveis entre os dois grupos. O nível de significância foi de p< ou = 0,05. Foi realizada também uma análise multivariada. A amostra foi analisada durante o período de novembro de 2006 a novembro de 2007. Não ocorreram os seguintes desfechos: infecção do sítio cirúrgico, antibiótico introduzido pelo médico no pós-operatório em até 30 dias após o procedimento odontológico e morte até o 15º dia após o procedimento odontológico. Os desfechos encontrados foram: necessidade de tomar analgésico após o 3º dia e até o 15º dia após o procedimento (3 no grupo 1 e 1 no grupo 2) e internação hospitalar até o 15º dia após o procedimento (2 no grupo 1 e 1 no grupo 2). A análise multivariada não alterou os resultados. Este estudo não demonstrou uma diferença entre utilizar uma ou duas doses de amoxicilina como profilaxia em procedimentos invasivos dentários em pacientes imunosuprimidos
Studies about antibiotic prophylaxis in immunosuppressed patients submitted to odontological invasive procedures are scarse, however there is already a consensus that these patients are in risk for post-operative infection in dentistry and that, therefore, they need antibiotic prophylaxis. It is not defined, however, the best prophylactic regimen for these patients. The aim of this study was to compare two regimens of antimicrobial prophylaxis in dental invasive procedures in immunosuppressed patients by chemotherapy for cancer or solid organ transplants. This is a randomized controlled study and it evaluated consecutive patients with cancer and that were submitted to chemotherapy in the last month and solid organ transplanted patients who needed exodontia or periodontal scaling and root planning as odontological treatment. This study was done in the Divisão de Odontologia of Hospital das Clínicas of Faculdade Medicina of the Universidade de São Paulo and it was included patients from the routine of the ambulatory who presented all the inclusion criteria and signed the informed consent. Patients were randomly assigned to one of the groups of prophylactic regimens (group 1 amoxicillin 500mg administered orally two hours before the procedure; group 2 amoxicillin 500mg administered orally two hours before the procedure and a second dose eight hours later) and had blood sample collected for culture immediately after the procedure, being followed up for one month. The total sample size was of 414 patients, being 207 in each group. Data were analyzed using the software SPSS Windows (version 13.0, Chicago IL). The characteristics of the patients of the 2 groups were compared using the chi-square test. The two groups were compared as to each outcome. A multivariate analysis was performed evaluating the groups as to the occurrence of any of the outcomes, by multiple logistic regression. The sample was evaluated between november of 2006 and november of 2007. The following outcomes did not occur: surgical site infection; systemic use of an antimicrobial drug within 30 days after the procedure and death by any reason within 15 days after the procedure. The other outcomes were: use of medication against pain after 3rd day after the procedure (three in group 1 and one in group 2) and hospitalization for any reason within 15 days after the procedure (two in group 1 and one in group 2). The multivariate analyses did not alter the results. This study did not demonstrate a difference between using one or two doses of amoxicillin as prophylaxis in invasive odontological procedures in immunosuppressed patients

O objetivo deste estudo in situ foi avaliar a microdureza superficial e longitudinal do esmalte de dentes com diferentes idades pós-eruptivas (antes da erupção na cavidade bucal, após 2 a 3 anos da erupção, após 4 a 10 anos da erupção e mais de 10 anos de erupção), submetidos aos desafios cariogênicos. Para isso, foram utilizados 24 espécimes de esmalte humano de cada idade pós-eruptiva, após um ordenamento conforme a dureza. Os espécimes foram aleatoriamente divididos entre doze voluntários. Durante o período experimental, os espécimes foram submetidos ao acúmulo de biofilme dentário, sobre o qual foi gotejada uma solução de sacarose a 20% oito vezes ao dia, para provocar um alto desafio cariogênico. Após 7 dias, uma das metades (direita ou esquerda) do aparelho recebeu profilaxia com jato de bicarbonato de sódio para remoção do biofilme dentário, seguido de um novo acúmulo de biofilme até completar o período experimental de 14 dias. A comparação entre as microdurezas superficial e longitudinal obtidas nos diferentes grupos foi realizada por meio da Análise de Variância e Teste de Tukey, adotando-se um nível de significância de 5%. Os resultados demonstraram que os valores de microdureza superficial inicial têm uma tendência crescente com o passar dos anos, sendo encontrada diferença estatisticamente significante apenas entre o esmalte incluso e o de mais de 10 anos de erupção. Depois do período in situ, os resultados obtidos mostraram que a porcentagem de perda de dureza superficial (%PDS) dos espécimes de esmalte com diferentes idades pós-eruptivas do grupo que recebeu e não profilaxia revelaram uma tendência decrescente dos valores de %PDS com o passar dos anos, estes valores não apresentaram diferença estatisticamente significante. No entanto, encontrou-se uma diferença estatisticamente significante entre o grupo que recebeu a profilaxia e o que não recebeu, independentemente da idade pós-eruptiva. Ao respeito da microdureza longitudinal, os resultados mostraram que o volume mineral, de forma geral, tem uma tendência crescente dos valores com o passar dos anos. Na análise individual de cada profundidade constatou-se que a 10µm existia uma diferença estatisticamente significante entre os espécimes inclusos e os de mais de 10 anos de erupção. Na profundidade de 30µm encontrou-se diferença significante apenas dos espécimes inclusos e de 2-3 anos sem profilaxia com todos os outros grupos restantes. Na profundidade de 50µm os espécimes inclusos apresentaram diferença significante com os de 4 a 10 anos e mais de 10 anos de erupção. Além disso, encontrou-se uma diferença significante entre o grupo que recebeu a profilaxia e o que não recebeu nestas profundidades, independentemente da idade pós-eruptiva. A partir da profundidade de 70µm os espécimes inclusos foram diferentes das outras idades pós-eruptivas, além disso, não houve diferença estatisticamente significante entre os grupos com e sem profilaxia. De acordo com as condições e com a metodologia adotada na presente pesquisa, foi possível concluir que houve diferença entre a microdureza superficial inicial dos espécimes com diferentes idades póseruptivas, mostrando um comportamento crescente de mineralização. Sendo, no entanto esta diferença significante somente entre os espécimes inclusos e os de mais de 10 anos de erupção. Quando os espécimes das diferentes idades pós-eruptivas foram submetidos a desafio cariogênico in situ, com e sem remoção do biofilme dentário e analisado tanto superficial quanto em profundidade mostraram um comportamento de perda de dureza decrescente de acordo com a idade de maturação e a profundidade do esmalte. A realização da remoção mecânica do biofilme, através da profilaxia com jato de bicarbonato de sódio, promoveu menor perda de dureza tanto superficialmente quanto em profundidade, sendo estatisticamente significante quando comparado com os espécimes que não receberam profilaxia. Os resultados sugerem que a susceptibilidade a cárie diminui com o passar dos anos, possivelmente pela maturação pós-eruptiva.
This in situ study evaluated the surface and longitudinal microhardness ofenamel in teeth at different posteruptive ages (before eruption in the oral cavity, 2-3 years after eruption, 4-10 years after eruption and more than 10 years after eruption), submitted to cariogenic challenges. The study sample was composed of 24 specimens of human enamel at each posteruptive age, after arrangement according to hardness. The specimens were randomly divided into twelve volunteers. During the study period, the specimens were submitted to accumulation of dental biofilm, by dripping a 20% sucrose solution 8 times a day, to induce a high cariogenic challenge. After 7 days, one half (right or left) of the appliance was submitted to prophylaxis with sodium bicarbonate jet to remove the dental biofilm, followed by further accumulation of biofilm until completion of the study period of 14 days. Comparison between the surface and longitudinal microhardness obtained for the different groups was performed by analysis of variance and the Tukey test, at a significance level of 5%. The results demonstrated that the initial surface microhardness values have a tendency to increase over the years, with statistically significant difference only between unerupted enamel and more than 10 years after eruption. After the in situ period, the results demonstrated that he percentage of loss of surface hardness (%LSH) of enamel specimens at different posteruptive ages in groups with and without prophylaxis exhibited a tendency to decrease the %LSH values with time, yet without statistically significant difference. However, there was statistically significant difference between the groups with and without prophylaxis, regardless of the posteruptive age. With regard to longitudinal microhardness, the results demonstrated that the mineral volume, in general, had a tendency to increase over the years. Individual analysis at each depth revealed that, at 10 µm, there was statistically significant difference between unerupted specimens and more than 10 years after eruption. At 30 µm, there was significant difference only between unerupted specimens and 2-3 years after eruption without prophylaxis compared to all other groups. At 50 µm, the unerupted specimens exhibited significant difference compared to 4-10 years and more than 10 years after eruption. Moreover, there was significant difference between the groups with and without prophylaxis at these depths, regardless of the posteruptive age. After 70 µm of depth, the unerupted specimens were different compared to the other posteruptive ages; moreover, there was no statistically significant difference between groups with and without prophylaxis. According to the present conditions and methodology, it was concluded that there was difference between the initial surface microhardness of specimens at different posteruptive ages, revealing increasing mineralization. However, this difference was significant only between unerupted specimens and more than 10 years after eruption. When specimens at different posteruptive ages were submitted to in situ cariogenic challenge, with or without removal of dental biofilm and submitted to both surface and depth analysis, decreasing loss of hardness was observed with the increase in maturation age and enamel depth. Mechanical removal of dental biofilm by prophylaxis with sodium bicarbonate jet promoted less loss of both surface and longitudinal hardness, with statistically significant difference compared to specimens not submitted to prophylaxis. The results suggest that the susceptibility to caries is reduced with time, possibly due to posteruptive maturation.

Guidelines regarding the prevention of infective endocarditis have been published by the American Heart Association (AHA) in 2007 and the National Institute for Health and Clinical Excellence, UK, (NICE) in 2008. These are contradictory, even though both are from developed countries. It is not known whether they are suitable for developing countries such as South Africa, nor is it known whether they are followed by general dental practitioners. The aim of the study was therefore to conduct a survey amongst dental practitioners in South Africa to determine knowledge of the guidelines and practises followed in antibiotic prophylaxis.

Abstract Dental caries plays a very important role on the health of the oral cavity, and it is one of the main reasons causing buccal diseases. Although there are various fluoride-containing commodities on the market, the prevalence of dental caries in Taiwan is always at a high level. Thus, we hope that research and development of fluoride strips can provide a more convenient and safe way to decrease the occurrence of dental caries. Sodium fluoride and carbopol(poly acrylic acid) are the most important components in the gel used to make fluoride-containing strips. We found that 40000 ppm NaF and 3g carbopol/100ml H2O provide appropriate viscosity for attaching to teeth and exhibit good diffusion rate of fluoride. We made fluoride-containing strips by spreading 500μm-thickness film on the PE membrane with the scraper and cut it into small size according to what we need. We measure fluoride concentration on the enamel surface by using SEM/EDX, and find that the fluoride adsorbed on the teeth achieves to the maximum after 8-hours sticking times. Then, we analyze effects of the fluoride-containing strips on demineralization-inhibition and remineralization-promotion by using the calcium electrode. We can know that fluoride strips can show excellent efficacy on demineralization-inhibition of dental enamel after 2 weeks by using it 4 hours a time, and two times a week. Besides, the ability of fluoride strips for remineralization-promotion of dental enamel is also confirmed after 4-hours sticking time and soaking teeth in remineralizing solution for 3 days. Thus, we can conclude that fluoride-containing strips have remarkable effects on prophylaxis of dental caries by in vitro study, and the advantage of convenience and safety makes it possess developmental potential.

Introduction: Regenerative endodontic procedures are used to treat immature teeth with pulpal necrosis in order to control infection, enable continued root development and enhance formation of a pulp like tissue in the canal. Canal disinfection is an integral part the regenerative endodontic process. Double antibiotic paste (DAP; i.e., equal parts of ciprofloxacin and metronidazole) has been successfully used for canal disinfection in regenerative endodontics. A comparison of the residual antibacterial effect of dentin treated with various dilutions of DAP pastes on biofilm formation has not yet been investigated thoroughly. Objectives: The aims of this in-vitro study were to investigate how concentration and time of treatment affect the residual antibacterial properties of DAP in preventing E. faecalis biofilm formation on human dentin. Materials and Methods: Extracted human teeth were used to obtain 4x4mm radicular dentin specimens. Each specimen was pretreated for 1 or 4 weeks with the 77 clinically used concentration of DAP (500 mg/mL), low concentrations of DAP (1, 5 or 50 mg/mL) loaded into a methylcellulose system, calcium hydroxide (Ca(OH)2), or placebo paste. After treatment, samples were rinsed and placed in sterile phosphate buffered saline (PBS) for three weeks. Samples were then inoculated with cultured E. faecalis and incubated in anaerobic conditions for three weeks to allow mature biofilm formation. The dentin samples were rinsed and biofilms detached. The detached biofilm cells were then diluted and spirally plated for enumeration on blood agar plates. The plates were then incubated for 24 h and the number of CFUs/mL was determined using an automated colony counter. Data was analyzed using Fisher’s Exact and Wilcoxon rank sum tests were used for statistical comparisons (α=0.05). Results: Dentin pretreatment for 4 weeks with 5, 50 or 500 mg/mL of DAP demonstrated significantly higher residual antibacterial effects and complete eradication of E. faecalis biofilms in comparison to a 1 week pretreatment with similar concentrations. However, dentin pretreated with 1 mg/mL of DAP or Ca(OH)2 did not provide a substantial residual antibacterial effect regardless of the application time. Conclusion: Dentin treated with 500, 50, or 5 mg/mL of DAP for 4 weeks was able to completely prevent the colonization of bacterial biofilm. Four-week treatment of dentin with DAP offers superior residual antibacterial effect in comparison to a one-week treatment. Intracanal application of DAP for 4 weeks during endodontic regeneration may offer an extended residual antibacterial effect.

Introduction: Triple antibiotic paste (TAP, 1000 mg/ml) is composed of equal portions of ciprofloxacin, metronidazole and minocycline and is used as an intracanal dressing to disinfect the infected immature root canal during endodontic regeneration procedures. Lower concentrations of TAP have been recommended to minimize detrimental effects on pulp stem cells. TAP can be retained within the dentin matrix and its continual release confers an antibacterial effect to the dentin. Objective: The aim of this in vitro study was to investigate the residual antibacterial effect of dentin treated with various concentrations of TAP loaded into a gel system. Materials and Methods: Radicular dentin slabs were prepared from human teeth after obtaining IRB approval. The slabs were sterilized and treated with methylcellulose-based TAP of 100 mg/mL, 10 mg/mL, 1 mg/mL, 1.5% NaOCl, placebo paste with no TAP, or a positive control group with pure 1000 mg/mL TAP. Samples in each group were treated with the assigned TAP concentration for three weeks or immersed in 1.5% NaOCl for five minutes (n =18 per group). All samples were then irrigated with sterile water followed by 17% EDTA and incubated in phosphate buffered saline for either 2 or 4 weeks. Samples were then inoculated with Enterococcus faecalis and incubated for an additional 3 weeks. Biofilm formed on each sample was then dislodged and spiral plated to evaluate the bacterial colony-forming units. Data were analyzed using Fisher’s Exact tests and Wilcoxon rank sum tests (α = 0.05). Results: Dentin treated with 10, 100, or 1000 mg/mL of TAP demonstrated significant residual antibacterial effects up to four weeks. However, only 100 mg/mL TAP was able to completely prevent bacterial colonization after four weeks. No considerable residual antibacterial effect was observed in dentin treated with placebo gel, 1 mg/ml TAP or 1.5% NaOCl. Conclusion: At least 10 mg/mL of TAP loaded into a methylcellulose system is required to achieve a substantial residual antibacterial effect for four weeks.

Este trabalho foi realizado com o intuito de abordar um tema de enorme interesse para todos os MDs e para a sua prática clínica diária. Os 3Ms geralmente erupcionam entre os 18 e os 25 anos de idade sendo que são o grupo de dentes que ficam impactados com maior frequência. A impactação dos 3Ms é um problema que afecta uma grande parte da população mundial. A extração de 3Ms assintomáticos é um dos procedimentos de maior controvérsia na Medicina Dentária, dado que podem causar inúmeros problemas. Para uma melhor tomada de decisão relativamente à extração profilática destes dentes deve saber-se quais as patologias e sintomas que possam surgir e os riscos inerentes à sua remoção cirúrgica. Este trabalho tem como objectivo rever a literatura existente sobre os sintomas e patologias associados à manutenção dos 3Ms nas arcadas dentárias.
This work was made with the aim of approaching a topic with huge interest for all Dentists and their daily clinical practice. Third Molars usually erupt around 18 and 25 years old being the teeth that get impacted more frequently. Third Molar impaction is a problem that affects a great part of the World’s population. Asymptomatic third molar extraction is one of the procedures with bigger controversy in Dentistry, given they can cause countless problems. For a better judgment regarding the prophylactic extraction of these teeth we must know the pathologies and symptoms that may appear and the risks inherent in its surgical removal. This work aims to review the existing literature about the symptoms and pathologies associated with the maintenance of third molars in dental arches.
