Annotation:
Local injection of glucocorticosteroid (GCS) is an effective treatment of painful conditions in the temporomandibular joint (TMJ). GCS can be administered using anatomical landmarks for orientation or by the use of simultaneous radiographic imaging. In the image guided technique the corticosteroid is mixed with a contrast medium and the injection visualized using radiography. The aim of this prospective pilot study was to compare the treatment effect of intra-articular GCS injection in the TMJ with- and without the use of simultaneous radiographic imaging. 13 patients (9 women and 4 men) with TMJ arthralgia received injection either with or without simultaneous radiographic imaging. Treatment effect was evaluated based on changes in clinical signs and symptoms before and 4-6 weeks after treatment. The symptoms included pain at rest and at jaw function, joint locking, pain index and global improvement. Clinical observations involved TMJ pain to palpation, maximal mouth opening, pain at maximal opening and joint sounds. The main findings were significant decreases in pain index and relief of familiar pain before and after treatment as well as a positive effect on global improvement regardless of administration technique. There were no significant differences between the two methods in treatment outcome. The results suggest that both administration techniques are comparable in treatment effect and should therefore rather be evaluated based on cost-effectiveness and radiation dose. It may be reasonable to apply the image-guided technique mainly when further diagnostic information is needed.

Annotation:
Temporomandibular joint disorders (TMD), an umbrella term referring to a group of orofacial pain disorders, including disc displacement and osteoarthritis, affect a significant portion of the general population, with prevalence of temporomandibular joint osteoarthritis (TMJ OA) at around 30%. The temporomandibular joint (TMJ) is intimately linked to mastication (and as such, diet), with research on animals and modern clinical studies suggesting that disorders of the TMJ may be connected to soft dietary composition and associated with a reduction of the craniofacial complex. Over the past 100,000 years, the size and shape of the human face has undergone marked changes, from large and robust, to relatively small and gracile. Concordantly, human diet has changed profoundly, first in the transition from hunter-gathering to agriculture, then again in the shift to the post-industrialised diet, markedly affecting the rate of caries and malocclusions, which have increased, and dental wear, the severity of which has notably decreased. The question remains as to whether these dietary shifts, particularly modernisation, have had an effect on the temporomandibular joint. This work aims to combine archaeological, evolutionary and clinical perspectives to provide a comprehensive understanding of the impact changes in human behaviour (primarily those related to diet) have had on the prevalence and distribution of temporomandibular joint disorders, specifically osteoarthritis. Three different skeletal populations (modern Americans, Medieval and post-Medieval Londoners and Prehistoric Native Americans) were examined for the severity of tooth wear, presence of TMJ osteoarthritis, morphology of the TMJ and tooth loss, as well as undergoing a metric and geometric morphometric analysis. The results suggest that differing patterns of subsistence can impact the distribution and frequency of TMJ OA, with rates of OA highest in the contemporary populations, this seeming to contradict previous archaeological theories on TMJ OA, which typically associated high levels of OA with heavy tooth wear and using the teeth as tools. The results of this research also suggest that different methodological approaches need to be used when analyzing TMJ OA, utilising diagnostic techniques that are more clinically relevant, in part due to the unique and complex nature of the TM joint.

Annotation:
As disfunções temporomandibulares (DTM) compreendem uma série de alterações funcionais que podem acometer a articulação temporomandibular (ATM), a musculatura mastigatória ou ambas simultaneamente. Os distúrbios internos da ATM são modalidades específicas de DTM que se manifestam clinicamente por ruídos articulares associados a movimentos mandibulares desarmônicos ou limitados e, freqüentemente, dor. Sua etiologia e fisiopatologia ainda são desconhecidas, mas sugere-se a participação de fatores de postura de cabeça e corporal em sua gênese e perpetuação. A pesquisa aqui relatada, com o objetivo de verificar possíveis relações entre postura corporal global e distúrbios internos da ATM, procedeu à comparação entre 30 indivíduos portadores de sintomatologia característica de distúrbios da ATM (grupo teste) e 20 indivíduos saudáveis (grupo controle). Os métodos utilizados foram: o clínico, que constou de anamnese e fichas padronizadas para avaliação de características do sistema estomatognático; traçados e análise por cadeias musculares em fotografias de postura corporal; e análise de radiografia de coluna cervical em perfil. A comparação entre os grupos teste e controle revelou maior curvatura lordótica da coluna cervical no grupo teste, pelo método de diagnóstico clínico. No grupo controle, 79% dos indivíduos apresentaram diagnóstico clínico de retificação de coluna cervical e em apenas 10,5% a curvatura de coluna cervical foi considerada hiperlordótica, ao passo que, no grupo teste, somente 41,4% dos indivíduos apresentaram diagnóstico clínico de retificação, 37,9% apresentaram curvatura lordótica fisiológica e 20,7% obtiveram diagnóstico de hiperlordose (p=0,03). O grupo teste apresentou ainda maior prevalência de elevação de ombros: 63,3% versus 30,0% (p=0,04). Nenhuma outra relação estatisticamente significante foi encontrada na comparação dos grupos teste e controle. Em um segundo momento, o grupo teste foi dividido em três subgrupos, de acordo com a gravidade da DTM, avaliada pelo Índice Disfuncional de Helkimo. Nessa análise de subgrupos nenhuma correlação estatística foi demonstrada; no entanto, o grupo com maior gravidade de DTM apresentou tendência, embora não significante estatisticamente, à maior prevalência de hiperlordose de coluna cervical (50%) observada em radiografia, bem como algumas discrepâncias posturais, como protrusão de cabeça (100%) e de ombros (100%) e aumento de lordose lombar (83,3%). Os resultados sugerem que a coluna cervical e ombros, possivelmente por estarem localizados nas adjacências do sistema temporomandibular, estão intimamente relacionados aos distúrbios internos da ATM. Por outro lado, as poucas associações estatísticas entre o grupo teste e o controle, aliadas à tendência a desarmonias posturais encontrada no grupo de maior grau de disfunção, levam a concluir que o papel da postura corporal na fisiopatologia desta seria de baixa relevância, podendo inclusive não constituir fator etiológico, mas uma decorrência da DTM.
The temporomandibular joint dysfunctions (TMD) embrace a variety of functional disturbances that may affect the temporomandibular joint (TMJ), masticatory musculature, or both simultaneously. TMJ internal derangements are a specific case of TMD, clinically presented by articular sounds associated to jerk or limited mandibular movements, and often pain. Its etiology and physiopathology are broadly unknown, but it has been suggested that head-neck and body posture factors take part in its genesis and perpetuation. This study aimed at verifying possible relationships between body posture and TMJ internal disarrangements, by comparing 30 subjects presenting typical TMJ internal disarrangement signs (test group) to 20 healthy subjects (control group). Methods used included: 1) clinical, by means of anamnesis and standard files for stomatognatic system characteristics evaluation; 2) plotting and muscular chain analysis on body posture photographs; and 3) lateral cervical spine radiographic analysis. The comparison between the test and control groups has shown sharp lordosis on test group subjects cervical spine, through clinical diagnostic methods; 79% of control group subjects were clinically diagnosed as having cervical spine rectification, and only 10.5% presented hiperlordosis; whereas in the test group 41.4% of subjects had clinically diagnosed cervical spine rectification, 37.9% had physiological cervical spine curvature and 20.7%, hiperlordosis (p=0.03). The test group presented an even higher prevalence of elevated shoulders: 63.3%, against 30% of control group (p=0.04). No other significant statistical relationship was found when comparing both groups. Later the test group was divided into three subgroups according to TMD degree of severity, evaluated by the Helkimo Dysfunctional Index, but the comparative analysis has shown no statistical correlations; nevertheless, the subgroup with most severe dysfunction presented a tendency, though not statistically significant, to higher cervical spine hiperlordosis prevalence (50%) observed on radiography, as well as some body postural alterations, such as head protrusion (100%), shoulder protrusion (100%), and increased lumbar lordosis (83.3%). These findings suggest that cervical spine and shoulders, possibly due to their position close to the temporomandibular system, are intimately related to TMJ internal disarrangement. On the other hand, the scarce statistical relationships between the test and control groups, allied to a tendency to certain body alterations found in the most severed-dysfunction group, lead to concluding that the role of body posture on TMD physiopathology would be of low importance, and would possibly not constitute a TMD etiological factor, but a consequence of it.

Annotation:
Intramuscular EMG of the lateral pterygoid muscles, surface EMG of the temporalis and masseter muscles, electrogoniometry and force measurements of the TMJ were synchronously used to investigate the biomechanical role of the two portions of the lateral pterygoid muscle in relation to internal derangement (ID) of the temporomandibular joint (TMJ). This study dealt with the EMG analysis of five static conditions: resting, resisted protraction, maximum voluntary contraction (MVC) in opening, in molar and incisor clenching of TMJ ID and control subjects. The analysis of variance results of the integrated linear envelop (LE) EMG showed no significant differences between the two groups. The integrated LE EMG of the SLP was significantly lower in the TMJ group during molar clenching (104$\mu$V $\pm$ 60.0 over 159$\mu$V $\pm$ 68.8 for a p =.020). The SLP seemed to have lost its discal stabilizing function during clenching. The integrated LE EMG signals of the ILP were significantly higher in the TMJ ID group during rest, resisted protraction and incisor clenching (p =.029, p =.046, p =.031 respectively). The ILP muscle has probably adapted to control the inner joint instability while continuing its own actions. The results of the isometric forces showed that TMJ ID subjects exhibited significantly lower molar bite forces (297.1N over 419N, p =.042) confirming that they have less muscle strength and tissue tolerance than subjects with healthy masticatory muscle system. Incisor bite forces, however, showed a tendency to be higher in the TMJ ID group (233N over 180.5N, p =.168), possibly resulting from the training of a protracted bite and/or hyperactivity of the ILP associated with ID. Therefore a neuromuscular adaptation could be occurring in TMJ ID masticatory system affecting muscular actions and forces. (Abstract shortened by UMI.)

Chapter I: Literature review on the Temporomandibular joint (TMJ) and Temporomandibular disorders (TMD) Chapter II: Systematic review of TMD in orthognathic patients This review was conducted to investigate the prevalence of temporomandibular joint dysfunction (TMD) in orthognathic patients and to determine the effect of the surgical intervention on the status of the temporomandibular joint (TMJ). A methodological process was applied for study selection, data management and quality assessment and meta-analyses were conducted where appropriate. This review identified 53 papers for inclusion and there was heterogeneity in the diagnosis and classification of TMD between the studies. Patients undergoing orthognathic treatment for the correction of dentofacial deformity and suffering from TMD appeared more likely to see an improvement in their signs and symptoms than deterioration, particularly with respect to pain related symptoms. This information should be given to prospective patients during the consent process, but it should be stressed that no guarantees can be made. Chapter III: TMD in orthognathic patients and a control group with no skeletal discrepancies Sixty eight orthognathic patients and 72 control subjects (with no anterior-posterior, vertical or transverse discrepancies) were recruited for this section of the PhD. Self-reported symptoms and clinical signs of TMD were recorded and compared between the two groups. A significant difference in TMD prevalence was observed between the controls (27.8%) and patients (44.1%), with the patients being more susceptible to TMD. However, although orthognathic patients appear more likely to suffer from TMD, whether treatment improves their TMJ condition is highly questionable. This issue should be highlighted in any informed consent process. Chapter IV: A longitudinal study of TMD in orthognathic patients Twenty orthognathic patients were followed longitudinally throughout treatment to establish whether TMD signs and symptoms altered during the course of treatment. Although no significant differences were found when comparing the pre-treatment (T1) findings with those prior to surgery (T2), sufficient individual changes in TMD signs and symptoms were observed to question the suitability of the "prior to surgery" time point as a baseline for comparisons in future studies. When comparing pre (T1) and post-treatment (T3) TMD changes, no significant differences were observed. This study supports the theory that TMD is a dynamic condition and signs and symptoms are likely to fluctuate throughout treatment. However, the small sample size in this study was clearly a limiting factor. Chapter V: TMJ information course: Comparison of the instructional efficacy of an internet-based TMJ tutorial with a traditional face-to-face seminar A TMJ tutorial was developed on a virtual learning environment (VLE) to enable students to enhance their examination and diagnostic skills and a randomised cross-over trial was then conducted. Thirty postgraduate students were recruited as participants and the success of this mode of teaching was compared with a conventional face-to-face seminar. This study found that both modes of teaching were equally effective in delivering information to students but teaching the topic twice enhanced the retention of knowledge. In addition the students reported positive perceptions of VLE learning and the feedback for this mode of teaching was comparable with traditional methods of teaching.

Resumo: Sistemas avançados de imagem, como a tomografia computadorizada de feixe cônico (TCFC) e a imagem por ressonância magnética (IRM) têm sido utilizados para avaliação da articulação temporomandibular (ATM). Dentre as entidades patológicas que mais comumente afetam a ATM está o deslocamento de disco (DD). O objetivo neste estudo foi verificar a posição da cabeça da mandíbula na fossa em imagens de TCFC e investigar sua relação com a posição do disco articular em IRM. Cinqüenta e dois pacientes da clínica de Ortodontia da FOUSP foram submetidos à RM bilateral das ATMs. Cem imagens de TCFC da ATM foram obtidas com o tomógrafo Newtom 3G. As reconstruções secundárias foram realizadas com o programa NemoScan e utilizadas para obtenção das medidas dos espaços articulares e verificação da posição da cabeça da mandíbula na fossa. Para a comparação das medidas dos espaços articulares e da posição da cabeça da mandíbula, diferentes diagnósticos da posição do disco articular foram reunidos em grupos, para os cortes sagital e coronal, de acordo com a direção do DD. Os resultados foram submetidos à análise de variância one way e teste de Tukey, ao teste de Kruskal Wallis e Dunn e ao teste exato de Fisher (a=0,05). A posição normal do disco articular foi a mais comumente observada, seguida pelo DD envolvendo o terço lateral da articulação. No corte sagital central, a posição da cabeça da mandíbula foi predominantemente concêntrica. Observouse diferença estatisticamente significante apenas para o espaço articular posterior, que se apresentou reduzido para o grupo 2S em relação aos grupos 3S e 4S. No corte coronal central, o espaço articular medial foi maior para o grupo 1C. O espaço articular lateral apresentou-se maior para os grupos 2C e 3C do que para os demais grupos. O espaço articular superior foi menor para o grupo 4C. O espaço articular medial apresentou-se maior do que o lateral para a maioria das ATMs avaliadas, exceto para as ATMs com DD rotacional anterolateral e lateral. Concluiu-se que a posição do disco articular teve influência nos espaços articulares nos cortes sagital e coronal centrais de TCFC da ATM. Outros elementos associados à articulação, tais como ligamentos e músculos da mastigação, além das variações anatômicas individuais, em conjunto, devem ser considerados.
Abstract: Advanced imaging systems, as cone beam computed tomography (CBCT) and magnetic resonance imaging (MRI) have been used for the assessment of the temporomandibular joint (TMJ). Among the pathologies occurring in the TMJ, disk displacement (DD) is one of the most common observed. The aim of this study was to verify condylar position within the fossa in CBCT images and to investigate its relationship with disk position as depicted in MR images. Fifty two patients from FOUSP Orthodontic Clinic were submitted to bilateral MRI of the TMJ. One hundred CBCT images of the TMJ were obtained using a Newtom 3G. Secondary reconstructions were accomplished with Nemoscan software. Articular space measurements and condylar position were compared between groups which were classified according to disk position, for sagittal and coronal planes, considering the direction of DD. Data was evaluated by using ANOVA one way and Tukey test, Kruskall Wallis and Dunn tests (a=0,05) and Fisher exact test. Normal disk position was the most frequently observed, followed by DD localized in the lateral third of the joint. In the central sagittal slice, condylar position was mainly concentric. Posterior joint space in 2S group was lower than 3S and 4S groups. In the central coronal slice, medial space was higher for 1C group. The lateral space was higher for groups 2C and 3C than for the other groups. The superior space was lower for the 4C group. Medial space was higher than the lateral space for all groups, except for the TMJs with rotational anterolateral and lateral DD. It was concluded that disk position had influenced articular space measurements in the sagittal and coronal central slices of the TMJ's CBCT. Other elements associated to the joint, such as attachments and masticator muscles, besides individual anatomical differences, should also be considered.

Resumo: Esta pesquisa avaliou a influência das flutuações hormonais do ciclo menstrual na força máxima de mordida (FMM) de voluntárias com e sem desordem temporomandibular (DTM). Foram selecionadas 28 voluntárias completamente dentadas entre 19 e 38 anos de idade (média de 23,9 anos), que não faziam uso de contraceptivos orais. As voluntárias foram divididas em dois grupos, sendo 15 com ausência de DTM (controle) e 13 diagnosticadas como portadoras de DTM de origem articular com ausência de sintomatologia dolorosa (grupo experimental), por meio do Reaserch Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). A FMM foi avaliada durante três ciclos menstruais completos, de forma bilateral na região dos primeiros molares, por meio da utilização de sensores com 2,25 mm de espessura. A mensuração foi realizada durante as quatro fases do ciclo menstrual: 1. fase menstrual; 2. fase folicular; 3. fase periovulatória; e 4. fase lútea, que foram identificadas por meio de teste de ovulação. Os resultados obtidos foram submetidos à análise estatística, sendo que a comparação dos valores da FMM entre os grupos independentes das fases do ciclo menstrual, assim como a comparação em cada uma das fases do ciclo, foram realizadas por meio do teste Mann-Whitney. Para a comparação entre as fases do ciclo menstrual para cada grupo estudado individualmente, os valores foram submetidos ao teste de Friedman. Os resultados demonstraram diferenças significantes (P<0,05) entre os grupos nas fases menstrual e folicular, sendo que as voluntárias com DTM apresentaram os maiores valores de FMM. Quando da comparação entre as fases do ciclo menstrual para os grupos avaliados observou-se que as voluntárias do grupo controle apresentaram os maiores valores (446,7 N) de FMM (P<0,05) durante a fase periovulatória, e as voluntárias com DTM apresentaram os menores valores (348,9 N) de FMM (P<0,05) durante a fase lútea. Concluiu-se que as flutuações hormonais decorrentes do ciclo menstrual influenciaram a força máxima de mordida de voluntárias saudáveis e com DTM.
Abstract: This study evaluated the influence of the hormonal fluctuations of the menstrual cycle in the maximum bite force (MBF) of volunteers with and without Temporomandibular Disorders (TMD). Twenty-eight overall dentate subjects who did not use oral contraceptives, aged 19-38 years (mean age 23.9 years), were selected to participate in this research. The volunteers were divided into 2 groups: 15 women without TMD (control group) and 13 women affected by articular form of TMD and absence of pain (experimental group) by means of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The MBF was assessed bilaterally in the first molar region using 2.25 mm thick sensors. The measures were made in four phases during each of three menstrual cycles identified by ovulation test: 1. menstrual, 2. follicular, 3 periovulatory and 4. luteal. The results were subject to statistical analyses. For the comparison of the values of MBF among the groups, regardless the phases of menstrual cycle, as well as the comparison in each one of the phases, they were accomplished through the Mann-Whitney test. For the comparison among the phases of menstrual cycle of each group analyzed individually, the values were submitted to the Friedman test. The results have shown statistically significant difference (p<0.05) among the groups in menstrual and follicular phases and the subjects with TMD have presented highest values for MBF. Among the phases of the menstrual cycle, it has observed that the volunteers of control group presented highest values (446.7N) of MBF (p<0.05) at the periovulatory and women with TMD showed lower values at the luteal phase (348.9N) (p<0.05). It was concluded that hormone fluctuations related to menstrual cycle have influenced MBF of the healthy volunteers and of the TMD.

Resumo: As disfunções temporomandibulares (DTM) são condições dolorosas que envolvem a articulação temporomandibular (ATM) e os músculos mastigatórios, apresentam maior prevalência, severidade e duração no sexo feminino e são comumente associadas à inflamação. Apesar das drogas antiinflamatórias não esteroidais (AINEs) serem frequentemente utilizadas no controle de dores inflamatórias, muitos pacientes podem apresentar intolerância ao tratamento prolongado e nem todos os pacientes com dor na ATM respondem aos efeitos de tais medicamentos. Sabe-se que a dor inflamatória possui um componente simpático que pode predominar em casos com menor sensibilidade aos AINEs. Assim, o objetivo deste trabalho foi avaliar a contribuição desse componente simpático na dor instalada da ATM. Para isso (1) Investigamos a participação de adrenoceptores ß1, ß2 e ß3 na nocicepção induzida por formalina na ATM de ratos e (2) Verificamos se existe um dimorfismo sexual no efeito desses b-bloqueadores sobre a nocicepção. De acordo com o objetivo (1): A co-administração de formalina com os antagonistas de receptores ß1, ß2 e ß3, Atenolol, ICI 118.551 e SR59230A respectivamente, reduziu significativamente a nocicepção induzida por formalina na ATM de ratos. De acordo com o objetivo (2): A co-administração de doses baixas do antagonista de adrenoceptores ß1 (6µg) ou ß2 (0,1µg) com formalina apresentou um efeito antinociceptivo em fêmeas mas não em machos, indicando a existência de um dimorfismo sexual sobre o efeito destes antagonistas. Esses resultados sugerem que o bloqueio de adrenoceptores beta, mais especificamente ß1, ß2 e ß3, diminui a dor da ATM. Além disso, demonstram que as fêmeas são mais sensíveis aos efeitos antinociceptivos dos antagonistas ß-adrenérgicos do tipo 1 e 2
Abstract: Temporomandibular disorders (TMD) are pain conditions that affect the temporomandibular joint (TMJ) and masticatory muscles. These conditions present higher prevalence, severity and duration in females and appear to be associated with inflammation. Although non-steroidal anti-inflammatory drugs have been frequently used in the control of inflammatory pains, many patients may be intolerant to the prolonged treatment and some of them may not respond to the effect of these medications. It is already known that inflammatory pain has a sympathetic component that may predominate in the cases less sensitive to the non-steroidal anti-inflammatory drugs. Therefore, in this study we investigated the contribution of this sympathetic component in TMJ' pain. Specifically we investigated (1) the participation of ß1, ß2 and ß3 adrenoceptors in the rat's TMJ nociception induced by formalin and (2) the existence of sexual dimorphism in the effect of ß-blockers in the TMJ nociception. Co-administration of formalin with ß1, ß2 and ß3 adrenoceptors antagonists, Atenolol, ICI 118.551 and SR59230A respectively, significantly reduced formalin-induced TMJ nociception. Co-administration of a low dose of ß1 (6µg) or ß2 (0,1µg) adrenoceptors antagonists with formalin significantly reduced formalin-induced TMJ nociception in females but not in males, indicating the existence of a sexual dimorphism in the effect of these antagonists. The findings of this study indicate that beta adrenoceptors, specifically ß1, ß2 and ß3 adrenoceptors significantly reduce TMJ pain. Furthermore, females are more sensitive than males to the antinociceptive effect of ß1 and ß2 adrenoceptor antagonists

Resumo: O objetivo nesta pesquisa foi avaliar a associação da prevalência de Desordens Temporomandibulares (DTM) em pacientes com otalgia, atendidos no Serviço de Otorrinolaringologia do Ambulatório Araújo Lima da Faculdade de Medicina da Universidade Federal do Amazonas, cujos exames médicos específicos tenham descartado causas otorrinolaringológicas para tais manifestações e, descrever a prevalência dos principais sinais e sintomas otológicos em pacientes com diagnóstico de DTM sem patologia otorrinolaringológica associada. Foram avaliados 500 pacientes com otalgia. O exame otorrinolaringológico consistiu na submissão dos pacientes a avaliações de orofaringoscopia, rinoscopia anterior e otoscopia, com o objetivo de afastar patologias específicas da área. Os pacientes voluntários com hipótese diagnóstica de desordens temporomandibulares foram encaminhados para avaliação e diagnóstico diferencial na área odontológica. O diagnóstico odontológico foi realizado por meio dos exames previstos na Ficha Clínica do CETASE/FOP-UNICAMP (Centro de Estudos e Tratamento das Alterações Funcionais do Sistema Estomatognático da Faculdade de Odontologia de Piracicaba - Universidade Estadual de Campinas). O teste estatístico utilizado para verificar associações significativas, foi o G-teste. O nível de significância utilizado no teste foi de 5%. Entre os 500 pacientes avaliados, 94 (18,8%) apresentaram disfunção temporomandibular (DTM). Para os pacientes que apresentavam diagnóstico sugestivo de DTM: a amostra foi significantemente maior para o gênero feminino e na quarta década de vida; a sensação de surdez ou "ouvido tapado" atingiu 72,3% da amostra estudada, seguido de cefaléia (53,8%), zumbido (29,8%) e tontura (26,6%). A amostra de pacientes com DTM foi bastante significativa para dores na nuca e/ou pescoço (79,8%), dores nas costas (74,5%), dor na região temporal (66,0%), dor na região masseterina (63,8%) e na região frontal (56,4%). O estalido foi o sinal mais informado (39,4%), seguido de creptação (10,6%) e sensação de papel amassado (2,1%). O diagnóstico da DTM é muito controverso, assim como a relação deste com os sintomas otológicos, sendo muito importantes outros estudos a cerca deste mesmo assunto
Abstract: This objective of this study was to evaluate the prevalence of temporomandibular disorders (TMD) in patients with otalgia, seen in the otorhinolaringology Service of the University of Amazon Medical School, whose specific medical exams have discharged otorrinolaringologic causes for such manifestations and to describe the prevalence of main otological signs and symptoms in patients with TMD diagnosis without otalgia with associated otorhinolaringological pathologies. This study evaluated 500 patients. The otorhinolaringological exam was constituted of orophryngoscopy, rinoscopy and otoscopy to discharge specific otorhinolaringological pathologies. The voluntary patients with TMD hypotheses were sent for odontologic evaluation and differential diagnosis. The odontologic diagnosis was made through exams of the CETASE/FOP - UNICAMP clinical file (Center of studies and treatment of estomatognatic system malfunctions of Piracicaba Dental School Campinas State University). The statistic test used to verify significant associations was G-test. The level of significance used in the test was 5%. From 500 patients evaluated, 94 (18,8%) had temporomandibular disfunction wich was significantly more frequent among women in their forties. The feeling of deafness or "blocked ear" was present in 72,3% of the sample studied followed by headache (53,8%), tinnitus (29,8%), dizziness (26,6%). The sample was very significant for neck pain (79,8%), back pain (74,5%), pain in the temporal region (66%), pain in the region of the masseter muscle (63,8%) and frontal sinus (56,4%). The click was the most reported sign (39,4%) followed by crackle (10,6%) and feeling of creased paper (2,1%). The diagnosis of TMD is controversial as well as its relation with otologic symptoms, so other studies are necessary to evaluate this relationship

Resumo: A disfunção temporomandibular pode afetar músculos mastigatórios, articulação temporomandibular (ATM) ou ambos; possui elevada prevalência nas mulheres e sintoma mais comum é a dor. Foi proposto determinar mínima concentração efetiva da piperina para ativar o Potencial Receptor Transiente Vanilóide da subfamília 1 (TRPV1) na região da ATM direita de ratas Wistar, nas condições: normalidade, inflamação crônica na ATM, estresse crônico e associação destas. Foram desenvolvidos 2 estudos experimentais, randomizados, duplo-cegos (protocolo nº 2633-1). No estudo I, 48 animais foram distribuídos aleatoriamente em seis grupos, e cada grupo recebeu 30 ?l na ATM de uma das soluções: solução padrão (10% de álcool etílico, 10% de Tween 80 e 80% de solução salina estéril) ou 1, 2, 3, 4 e 5 ?g de piperina diluída em 100 ml da solução padrão. No estudo II, 144 ratas foram aleatoriamente distribuídas em grupos: A - inflamação crônica na ATM direita induzida pelo Adjuvante Completo de Freund; B - estresse crônico provocado pelo modelo crônico de estresse; C - associação dessas condições. Esses grupos foram subdivididos (n = 8), e injetados na ATM 30 ?l das mesmas soluções descritas previamente. Nos estudos, as ratas, na fase diestro do ciclo hormonal, após injeção de uma das soluções, foram avaliadas quanto ao comportamento nociceptivo, que consistia em quantificar o número de vezes que as ratas levantaram a cabeça abruptamente e tempo dispendido, em segundos (s), para coçar a região orofacial. Cada levantar da cabeça seguiu padrão uniforme de 1 segundo de duração, assim, os comportamentos foram expressos em função do tempo, possibilitando somatória. Para comparação estatística, foi empregado análise da variância e teste de Tukey-Kramer (P< 0,05). No estudo I, existiu diferença significante para comportamento de coçar a região orofacial entre os grupos de 2 ?g e 5 ?g (100,37 ± 63,81 s; 100,0 ± 60,5 s, respectivamente) e o controle (33.37 ± 18,48 s), e somatória dos comportamentos entre 2?g (130,87 ± 257,88 s) e o controle (62.75 ± 14,81 s). No estudo II, no grupo A, houve diferenças estatísticas significativas para os comportamentos de levantar a cabeça no grupo de 5?g (69,5 ± 16,44 s) e o controle (41,13 ± 15,06 s); coçar a região orofacial entre 4?g (51,5 ± 28,73 s) e o controle (14,71 ± 7,54 s), e na somatória entre 4 e 5?g (105,37 ± 22,64 s; 115,50 ± 35,14 s, respectivamente) e o controle (52,86 ± 17,46 s). No grupo B, nos comportamentos de levantar a cabeça entre 4 ?g (85,87 ± 19,21 s) e o controle (49,87 ± 10,70 s); coçar a região orofacial entre 5 ?g (48,25 ± 27,25 s) e o controle (35,75 ± 12,69 s). No grupo C, não houve diferença significante nos subgrupos. Assim, 0,02 ?g/ml de piperina mostrou-se a concentração mínima eficiente para provocar estímulo nociceptivo na condição de normalidade; a solução de 0,04 ?g/ml de piperina, para os grupos de inflamação crônica articular e de estresse crônico e para o grupo de associação das condições não foi evidenciado diferença estatística significante
Abstract: Temporomandibular Dysfunction may affect the masticatory muscles, temporomandibular joint (TMJ) or both, has high prevalence in women and most common symptoms is pain. It was proposed to determine minimal effective concentration of piperine to activate the transient receptor potential vanilloid subfamily 1 (TRPV1) in the right TMJ in Wistar female rats under the conditions: normal, chronic inflammation in the TMJ, chronic stress and inflammation and stress combination. It was developed two randomized double-blind experimental studies (n. 2633-1). In study I, 48 animals were randomly divides into six groups, each group received 30 ?l into the TMJ one of this solutions: standard solution (80% sterile saline, 10% Tween 80 and 10% ethyl alcohol) or 1, 2, 3, 4 and 5 ?g of piperine diluted in 100 ml of standard solution. In study II, 144 rats were randomly divided into groups: A - chronic inflammation in the right TMJ induced by Freund's Complete Adjuvant; B - chronic stress caused by chronic stress model; C - association of these conditions. These groups were divided (n = 8), and it was injected into the TMJ 30 ?l of the same solutions as previously describe. In both studies, rats in diestrous phase of the hormonal cycle, after injection of the solution, were assessed for nociceptive behavior, which consisted in quantify how many times the rats flinched its head and the time spent, in seconds (s), to rub the orofacial region. Each head flinch followed uniform pattern of 1 second duration, and the behaviors were expressed as time function, allowing the sum. For statistical comparison, it was used variance analysis and Tukey-Kramer (P<0.05). In study I, there was a significant difference for rubbing orofacial region between groups of 2 ?g and 5 ?g (100,37 ± 63,81 s, 100 ± 60,5 s, respectively) and control (33,37 ± 18,48 s), and the sum of the behaviors between 2?g (130,87 ± 257,88 s) and control (62,75 ± 14,81 s). In study II, in group A, there were statistical differences for head flinch behavior between 5?g (69,5 ± 16,44 s) and control (41,13 ± 15,06 s) groups; for rubbing orofacial region between 4?g (51,5 ± 28,73 s) and control (14,71 ± 7,54 s), and for the sum, among 4 and 5?g (105,37 ± 22,64 s, 115,50 ± 35,14 s, respectively) and controls (52,86 ± 17,46 s). In group B, for head flinching behavior there was significant difference between 4 ?g (85,87 ± 19,21 s) and control (49,87 ± 10,7 s); rubbing orofacial region, between 5 ?g (48,25 ± 27,25 s) and control (3,.75 ± 12,69 s). In group C, there was no significant difference in the subgroups. Thus, 0,02 ?g/ml of piperine showed the lowest concentration effective to cause noxious stimulation in normal condition, the solution of 0,04 ?g/ml of piperine, for groups of chronic joint inflammation and chronic stress and for association conditions group there was not statistical significant difference

Introdução: as escalas, como instrumentos de avaliação, são fundamentais no diagnóstico precoce e correto das disfunções temporomandibulares (DTM), assim como no registo da evolução terapêutica. Para isso é necessária a compreensão e precisão das suas questões. Objetivo: traduzir e adaptar a Temporomandibular Joint Scale (TMJ scale) para a Língua Portuguesa, analisando a sua confiabilidade e validade de constructo. Métodos: um estudo observacional prospectivo foi realizado com pacientes da Universidade Fernando Pessoa. Foi utilizado o método descritivo de tradução e adaptação de instrumentos de medida, passando por cinco fases: tradução, síntese das traduções, retrotradução, comité de peritos e pré-teste da versão final. Após a tradução de inglês para português, foram analisada as médias dos scores, a confiabilidade do instrumento e a consistência interna da escala. Resultados: um total de 63 pacientes responderam às questões da TMJ scale, em dois momentos. No teste do coeficiente de correlação intraclasse (ICC) obteve-se um valor de 0,998, com um intervalo de confiança (IC) 95%, e no teste alfa de Cronbach obteve-se 0,921 no 1º momento e 0,918 no 2º momento o que demonstra uma consistência interna excelente. Conclusão: a versão final traduzida e adaptada para a língua portuguesa do instrumento TMJ Scale mostrou ter uma boa validade de constructo, sendo, assim, um instrumento confiável para a obtenção de um diagnóstico clínico e para o registo de alterações dos sinais e sintomas da DTM.
Introduction: Scales, as evaluation instruments, are fundamental in the early and correct diagnosis of temporomandibular disorders (TMD), as well as in the record of therapeutic evolution. This requires understanding and accuracy of their questions. Purpose: translate and adapt Temporomandibular Joint Scale (TMJ scale) into Portuguese Language, analysing its reliability and construct validity. Methods: A prospective observational study was conducted with patients from University Fernando Pessoa. The descriptive method of translating and adapting measuring instruments was used through five phases: translation, synthesis of translations, back-translation, expert committee and pre-test of the final version. After translating from English to Portuguese, we analysed the scores, the reliability of the instrument and the internal consistency of the scale. Results: A total of 63 patients answered the TMJ scale questions in two moments. In the intraclass correlation coefficient test (ICC), a value of 0.998 was obtained, with a 95% confidence interval (CI), and in the Cronbach's alpha test, 0.921 was obtained in the 1st moment and 0.918 in the 2nd moment, which demonstrates an excellent internal consistency. Conclusion: The final version translated and adapted to the Portuguese language of the TMJ Scale instrument showed good construct validity and is therefore a reliable tool for obtaining a clinical diagnosis and for recording changes in TMD signs and symptoms.

Resumo: A realização desta pesquisa teve por propósito avaliar a articulação temporomandibular de indivíduos livres de estresse. Fizeram parte da amostra, 40 indivíduos, residentes do povoado de Curimans (Ce) que, após serem submetidos a um teste específico do Manual do Inventário de Sintomas de Estresse para adultos de LIPP (ISSL), foram classificados como livres de estresse. Os indivíduos foram submetidos a Exame Clínico e Exame por imagem que se constituiu de Ressonância Magnética. As articulações temporomandibulares foram avaliadas individualmente e após a análise dos resultados obtidos foi observado que ruído foi o sintoma mais relatado durante a anamnese (30% da amostra); mastigação unilateral ¿sempre¿ e ¿às vezes¿ foi o hábito parafuncional mais citado (62,5%). Com relação ao exame clínico, movimento mandibular limitado ocorreu em 22,5% dos indivíduos; desvio ou deflexão ocorreu em 30% da amostra; dor à palpação ocorreu em 6,25% das articulações e dor durante a função em 8,75%; dor muscular estava presente em 35% da amostra. A maior ocorrência foi para ruído, sendo observado em 38,75% das articulações. Com relação ao exame por imagem, deslocamento de disco foi observado em 24 articulações (30% da amostra), sendo que deslocamento sem redução foi observado somente em 02 articulações. Posição do côndilo foi observada estar alterada em 23,75% da amostra, sendo o posicionamento posterior o que mais ocorreu (16 articulações); mobilidade condilar anormal foi observada em 26 articulações. Utilizando-se o Teste Exato de Fischer e o Teste do c 2 como análises estatísticas, observou-se não haver relação entre dor e posição do disco (p=0,22); entre dor e função do disco (p =0,54); entre posição do disco e trajetória mandibular (p =0,48). Verificou-se haver relação entre posição do disco e ruído articular (p = 0,0019) e entre posição do disco e posição do côndilo da mandíbula (p = 0,005). Somente dois indivíduos apresentaram dor, limitação de movimento da mandíbula e ruído articular; sendo que um apresentava deslocamento de disco. Concluiu-se assim, que a ausência de estresse é um forte fator para o não desencadeamento de disfunção temporomandibular
Abstract: This study was conducted to evaluate the temporomandibular joint of stressfree individuals. The sample comprised 40 individuals living in the area of Curimans (CE), who were classified as stress-free after undertaking the Lipp Stress Symptoms Inventory for Adults. The subjects were submitted to clinical examination and imaging examination, which comprised magnetic resonance imaging. The temporomandibular joints were evaluated individually and analysis of the outcomes achieved revealed that noise was the symptom most often reported during anamnesis (30% of the sample); unilateral mastication was the most frequently reported parafunctional habit ¿always¿ and ¿sometimes¿ (62.5%). With regard to clinical examination, there was limited mandibular movement in 22.5% of individuals; deviation or deflection occurred in 30% of the sample; pain to palpation affected 6.25% of joints, and pain during function in 8.75%; muscle pain was present in 35% of subjects. The highest frequency was observed for noise, namely in 38.75% of joints. As to the imaging examination, disc displacement was observed in 24 joints (30% of the sample), being that displacement without reduction was observed in only 2 joints. The condyle position was altered in 23.75% of the sample, with predominance of posterior positioning (16 joints); abnormal condylar mobility was found in 26 joints. Application of the Fisher¿s exact test and c2 test as statistical analysis revealed no relationship between pain and disc positioning (p=0.22); pain and disc function (p=0.54); disc positioning and mandibular pathway (p=0.48). A relationship was observed between the disc positioning and joint noise (p=0.0019) and between disc positioning and condyle positioning (p=0.005). Only two individuals reported pain, limited mandibular movement and joint noise, one of which presented disc displacement. Thus, it was concluded that absence of stress is a strong factor for non-appearance of temporomandibular dysfunction

Abstract The study was undertaken to determine the prevalence of facial pain and the association of facial pain with temporomandibular disorders (TMD) as well as with other factors, in a geographically defined population-based sample consisting of subjects born in 1966 in northern Finland, and in a case-control study including subjects with facial pain and their healthy controls. In addition, the influence of conservative stomatognathic and necessary prosthetic treatment on facial pain and TMD was evaluated in a sample of patients with facial pain. In the age group of 31-32-year-olds, facial pain was reported by 12 % of men and 18 % of women. Reported facial pain was strongly associated with TMD symptoms, and a relation was also seen with other factors, i.e. certain occlusal factors, previous traumas, other pain conditions in the body, clinically assessed tenderness in the neck muscles, and psychological problems, such as depressiveness and alexithymia. Conservative treatment of TMD seemed to be effective in relieving facial pain in a one-year follow-up. It can be concluded that facial pain is quite a common symptom with several both localized and generalized associated factors. Conservative stomatognathic treatment is recommended in the case of TMD-related facial pain. The possibility of psychological problems should be taken into account, especially in complex and chronic cases. When no response to conservative stomatognathic treatment is achieved, a multidisciplinary team, including mental health professionals, will be needed in both diagnosis and treatment. This study provides support for the suggestion that in future individualizing treatment of the patients with facial pain should be based on patient characteristics, which may improve treatment efficacy.

Includes bibliographical references. Temporomandibular joint (TMJ) pain and dysfunction occurs commonly in the general population. Various surgical procedures have been used in the management of those patients who have not responded to conservative measures. Research into the surgical management of TMJ dysfunction and pathology has been restricted due to the lack of a suitable animal model. This study was undertaken initially to develop the sheep as an animal for TMJ research. The study has shown that Australian Merino sheep, with a TMJ broadly similar in size to humans, provides a satisfactory experimental model for TMJ research.

A simulação de articulações baseada em anatomia, além de melhorar o realismo de animações do corpo humano na área da computação gráfica, tem se tornado uma importante ferramenta no auxílio ao diagnóstico médico e nas estimativas de resultados pósoperatórios, simplificando e melhorando o planejamento cirúrgico. Entretando, para uso efetivo em aplicações médicas, é necessário modelar as articulações de acordo com individualidades de cada paciente. Neste contexto, este trabalho propõe um modelo do conjunto de articulações temporomandibulares (ATMs) baseado em anatomia, modelo esse construído a partir de dados reais que representam a geometria e o movimento mandibular de um paciente normal. A modelagem aqui proposta apresenta uma topologia de duas juntas interdependentes, de maneira que o objeto geométrico que representa a mandíbula é associado a mais de uma junta. O modelo geométrico foi obtido de um indivíduo com ATM normal. O modelo padrão de como a ATM se movimenta é obtido a partir de cinemática inversa aplicada aos pontos da curva incisal capturada do mesmo indivíduo. Para reproduzir o movimento da mandíbula, a simulação trata as colisões entre os ossos da mandíbula e do crânio, facilitando, desta maneira, o entendimento de como forma e função interagem neste complexo sistema. Todas as fases da modelagem foram verificadas usando dados reais. Um modelo como este tem um grande potencial de prover dados úteis para médicos e dentistas realizarem diagnóstico de patologias e planejamento de cirurgias. O modelo foi usado para analisar como a forma e função são relacionadas nos movimentos de depressão e elevação da mandíbula e na mastigação. É apresentada também a aplicação do mesmo modelo de movimento da ATM para diferentes modelos de mandíbulas e maxilas, representando diferentes pessoas e diferentes patologias. Para atingir este objetivo, a malha do crânio padrão foi modificada manualmente para simular patologias conhecidas. Além disso, foram usados dados reais advindos de análises cefalométricas para modificar o modelo geométrico original com o intuito de representar a morfologia de pessoas diferentes sem submetê-las a exames de tomografia.
Beyond improving the realism of human body animation in entertainment graphics applications, the simulation of anatomical joints has become an important tool in aiding medical diagnosis as well as in the estimation of postoperative results, simplifying and improving surgical planning. However, for effective use in such medical applications, it is necessary to model the articulation in accordance with specificities of each patient. In this context, this work proposes a model of the temporomandibular joints (TMJs) set based on anatomy and built from real data representing geometry and movement of a normal patient. The model proposed here presents a topology of interdependent joints in such way that the geometric object that represents the jaw is associated to more than one joint. A geometric model of the skull was obtained from an individual with a normal TMJ. The basic model of how TMJ moves is obtained from inverse kinematics applied to the points of the incisal motion path captured from the same individual. To actually reproduce the movement of the mandible, the simulation treats the collision between the bones of the jaw and skull, facilitating the understanding of how form and function interact in this complex system. All phases of the modeling process were checked using real data. A model like this has a great potential to provide physicians and dentists with useful data for diagnosis and surgery planning. We use our model to analyze how form and function are closely related in the movements of opening and closing the mouth as well as mastication. We also show how the same model of TMJ movement can be applied to different mandible-maxilla models, representing different people and different pathologies. To accomplish that we manually modified the standard skull to simulate different, well-know pathologies but also used real data from cefalometric analysis to tailor our geometric model to represent skull morphology of different people without submitting them to computer tomography exams.

A síndrome de Moebius (SM) é pouco freqüente e caracterizada por paralisia total ou parcial de certos pares cranianos, obrigatoriamente VI e VII, podendo associar-se a outras anormalidades. Clinicamente ocorre falta de expressão facial, hipoplasia da língua, micrognatia, lábio curto e maloclusão. Disfunção temporomandibular (DTM) não tem sido estudada em pacientes com SM. O objetivo deste estudo é conhecer a prevalência de DTM em pacientes com SM e comparar a incidência e tipo de DTM com um grupo controle. Para tanto, foi realizado um estudo clínico caso controle observacional randomizado, no Centro de Atendimento a Pacientes Especiais (CAPE) da Faculdade de Odontologia da Universidade de São Paulo (FOUSP), entre julho de 2007 e dezembro de 2009, que avaliou 101 pacientes divididos em dois grupos: Grupo de estudo (GE) composto por 36 pacientes com SM, sendo 16 do gênero masculino e 20 do gênero feminino, com idade média de 10,2 anos, variando de 3 a 18 anos de idade; e grupo controle (GC) composto por 65 pacientes sem SM e sem nenhuma deformidade crânio facial, sendo 36 do gênero masculino e 29 do gênero feminino, com idade média de 10,7 anos, variando entre 3 e 18 anos. Nossos resultados mostraram que dos 36 pacientes do GE, 20 tinham DTM ou sinal de DTM (bruxismo). Desses 20 pacientes com DTM, 15 realizaram tomografias computadorizadas de ATM (TCs). Dos 65 pacientes do GC, 8 tinham DTM ou sinal de DTM (bruxismo) e 6 concordaram em realizar as TCs. Foram obtidas imagens volumétricas multiplanares e 3D. As alterações morfológicas indicando processo degenerativo encontrado nos exames de imagem encontradas nos dois grupos foram semelhantes. Concluimos que DTM é mais freqüente em pacientes com SM e que o diagnóstico em idade tenra pode representar uma oportunidade de prevenção e tratamento precoce da doença evitando seqüelas futuras. Por esta razão a avaliação da ATM deve ser incluída no exame clínico odontológico rotineiro de pacientes com a SM.
Moebius syndrome (MS) is rare and characterized by partial or total paralysis of some cranial nerves, unavoidably VI and VII, and may be associated with other abnormalities. The clinical aspects include lack of facial expression, hypoplasia of the tongue, micrognathia, short lip and malocclusion. Temporomandibular Joint disorders (TMJ) has not been studied in patients with MS. The aim of this study is to assess the prevalence of TJD in patients with MS and to compare the incidence and type of TMJ with a control group. We conducted a case-control randomized observational clinical study at the Special Care Dentistry Center, Dental School, University of São Paulo, between July 2007 and December 2009, which evaluated 101 patients divided into two groups: Study group (SG), composed of 36 patients with MS, 16 males and 20 females, mean age 10.2 years, ranging from 3 to18 years of age, and the control group (CG) composed of 65 patients without MS and with no craniofacial deformity, 36 male and 29 female, mean age 10.7 years, ranging between 3 and 18 years. Among 36 patients of the SG, 20 had TMJ. Among them, 15 were submitted to computed tomography (CT). Of the 65 CG patients, 8 had TMJ and 6 were submitted to CTs. Volumetric multiplanar and 3D images were obtained. The morphological changes of the TMJ demonstrating the pattern of the degenerative process found in patients with SM was similar to that found in people from control group. We concluded that the prevalence of TMJ in patients with MS is higher in SM patients and the diagnosis at an early age may represent an opportunity for prevention and early treatment of disease by avoiding future sequels. For this reason the evaluation of the TMJ should be included in routine clinical dental examination of patients with MS.

O objetivo deste trabalho foi determinar um intervalo de pressão capaz de estimular resposta dolorosa em pacientes com sinais e sintomas compatíveis com Disfunção Temporomandibular (DTM), quando comparado a um grupo controle. Para isso, foram selecionados 77 pacientes com sinais e sintomas de DTM de origem miogênica concomitante ou não com alguma patologia articular. Para o grupo controle, foram selecionados 75 indivíduos livres de qualquer queixa dolorosa compatível com DTM. Os indivíduos dos dois grupos foram palpados por um único examinador nos seguintes pontos: corpo do masséter, temporal anterior, temporal médio e temporal posterior. Os dados obtidos foram analisados estatisticamente num nível de significância de 5%. O grupo sintomático apresentou limiar de dor à pressão (LDP) significativamente menor em comparação ao grupo controle (p < 0,001). O masséter apresentou LDP significativamente menor, seguido pelo temporal anterior, médio e posterior (p < 0,001). O lado direito apresentou LDP significativamente menor que o lado esquerdo (p=0,033). Obteve-se uma correlação negativa significativa entre o LDP obtido e a Escala de Análise Visual (p < 0,001). Não foi encontrada correlação entre o LDP obtido e o tempo de experiência com a dor (p=0,310). Foi verificado que o intervalo de pressão mais confiável para o masséter foi de 1,01 - 1,5 kg/cm2, para o temporal anterior e médio foi de 1,51 - 2 kg/cm2 e para o temporal posterior foi de 2,01 - 3 kg/cm2. Os autores concluíram que a palpação mostrou ser um exame confiável para se detectar sensibilidade muscular em pacientes de DTM
The aim of this study was to determine a digital pressure interval able to elicit painful response in patients with signs and symptoms of Temporomandibular Disorders (TMD) when compared to a comparison group. Seventy-seven individuals with myogenic TMD comprised the symptomatic group, while seventy-five TMD symptom-free individuals were selected as controls. The pressure pain thresholds (PPT) were obtained with the aid of an algometer by pressuring the following muscles: masseter and anterior, medium and posterior temporalis. Values of sensitivity and specificity were determined for different pressure intervals. A lower PPT was found for all muscles in the symptomatic group (p < 0,001). The lowest PPT was found for the masseter muscle, followed by the anterior, medium and posterior temporalis. The left side has shown higher PPT than the right side (p < 0,05). A significant negative correlation was found between the PPT and the Visual Analogue Scale (p < 0,001). However, a significant correlation between the PPT and the time of pain experience was not found (p < 0,05). The authors concluded that, within the limitations of this study, the most appropriate pressure interval was 1,01 - 1,5 kg/cm2 for the masseter, 1,51 - 2 kg/cm2 for the anterior and medium temporalis, and 2,01 - 3 kg/cm2 for the posterior temporalis. Yet, according to the above figures, a standardized palpation can be considered a reliable technique in the examination of TMD patients

O diagnóstico clínico de desordens temporomandibulares é bastante complexo e, muitas vezes são necessários exames de imagem para complementar a investigação. A Imagem por Ressonância Magnética (IRM) é descrita como padrão-ouro na avaliação dos tecidos moles da articulação temporomandibular (ATM), entretanto a literatura mostra resultados conflitantes quanto à reprodutibilidade do método. Isso se deve a fatores relacionados à qualidade da imagem, como a força do campo magnético, e às condições do examinador. O objetivo do estudo foi avaliar a reprodutibilidade de diagnósticos da ATM por IRM em unidades de 0,5 e 1,5T. Exames de 212 pacientes (134 de 0,5T e 78 de 1,5T) foram avaliados por um examinador treinado e cegado. Nove condições foram avaliadas quanto à presença ou ausência de alteração. A concordância dos diagnósticos foi maior que 80% para ambas as unidades e não houve diferença significativa entre elas (P > 0,05). Alta reprodutibilidade foi obtida para deslocamento anterior de disco sem redução (κ = 0,82 para 0,5T e 0,80 para 1,5T), hipermobilidade (κ = 0,84 e 0,90) e hipomobilidade (κ = 0,80 e 0,95), enquanto valores apenas regulares foram alcançados para deslocamento anterior de disco com redução (κ = 0,48 e 0,42) e alteração de forma do disco (κ = 0,45 e 0,37). De maneira geral, os diagnósticos por IRM em 0,5 e 1,5T apresentaram alta concordância. Entretanto, a menor reprodutibilidade para deslocamento anterior de disco com redução e alteração de forma do disco evidencia a dificuldade do diagnóstico dessas condições.
Clinical diagnosis of temporomandibular disorders is complex making the professional often refer to imaging for complementary research. Magnetic Resonance Imaging (MRI) is described as the gold standard in the evaluation of the temporomandibular joint (TMJ) soft tissues, however the literature shows conflicting results regarding the reproducibility of the method. This is due to factors related to image quality, as the field strength, and the conditions of the rater. The aim this study was to assess the reproducibility of TMJ diagnoses at 0.5 and 1.5T MRI. Examinations of 212 patients (134 of 0.5T and 78 of 1.5T) were evaluated by a trained and blinded rater. Nine conditions were evaluated for the presence or absence of change. The diagnostics agreement was greater than 80% for both units and there was no significant difference between them (P > 0.05). High reproducibility was obtained for anterior disc displacement without reduction (κ = 0.82 at 0.5T and 0.80 at 1.5T), hypermobility (κ = 0.84 and 0.90) and hypomobility (κ = 0.80 and 0.95), while only regular values were achieved for anterior disc displacement with reduction (κ = 0.48 and 0.42) and disc deformity (κ = 0.45 and 0.37). MRI at 0.5 and 1.5T showed high agreement. However, the lower reproducibility for anterior disc displacement with reduction and disc deformity highlights the difficulty in diagnosing these conditions.

O objetivo deste estudo foi o de contribuir para a validação da ultra-sonografia como um exame complementar para o diagnóstico do deslocamento do disco da articulação temporomandibular com redução. Os padrões ultra-sonográficos encontrados em articulações com deslocamento foram comparados com os encontrados em articulações normais, valendo-se de critérios objetivos e da ressonância magnética como padrão-ouro. Foram estudados prospectivamente 36 pacientes na faixa etária de 18 a 60 anos de idade, com média de 31 anos, sendo 31 do sexo feminino e 5 do masculino, perfazendo um total de 69 articulações (39 com deslocamento do disco com redução e 30 livres de deslocamentos). As ultra-sonografias foram realizadas com um transdutor linear de 6-12 MHz, orientado para a obtenção de imagens estáticas e dinâmicas, nos planos coronal e axial inclinado (plano de Camper). O diagnóstico de deslocamento do disco foi firmado de acordo com critérios objetivos e mensuráveis, baseados em dois sinais ultra-sonográficos indiretos. O primeiro deles foi o aumento da distância entre o ponto mais anterior da cápsula da articulação temporomandibular e o ponto mais anterior do côndilo mandibular (distância cápsula anterior-côndilo), medida nas imagens estáticas. O segundo foi a ocorrência de diminuição e aumento súbitos da distância cápsula anterior-côndilo, observado nas imagens dinâmicas durante a abertura e fechamento da boca, indicando redução e deslocamento, respectivamente. A análise estatística dos resultados, mediante aplicação de regressão logística, indicou a ocorrência de deslocamento anterior do disco nos casos em que a medida da distância cápsula anterior-côndilo com a boca fechada foi superior a 2,2 mm (na presença de diminuição e aumento súbitos) e 4,0 mm (na ausência de diminuição e aumento súbitos). Nos casos de deslocamento anterior com redução, verificou-se que as medidas da distância cápsula anterior-côndilo obtidas com a boca aberta são menores do que as obtidas com a boca fechada e tendem a se aproximar dos valores médios de 1,4 mm e 2,4 mm, respectivamente na presença de redução total e parcial. A técnica ultra-sonográfica proposta possibilitou o diagnóstico de deslocamento anterior do disco com acurácia de 88,4%, sensibilidade de 84,6%, especificidade de 93,3%, taxa de falso positivo de 5,7% e taxa de falso negativo de 17,6%. Acreditamos que este estudo possa contribuir para o uso da ultra-sonografia no diagnóstico dos desarranjos internos da articulação temporomandibular, com a apresentação de critérios objetivos para o diagnóstico do deslocamento anterior do disco.
The purpose of this study was to contribute to the validation of ultrasonography for the diagnosis of temporomandibular joint disc displacement with reduction. The ultrasonographic patterns found in joints with disc displacement were compared with the ones found in normal joints, by means of objective criteria and using magnetic resonance imaging as the gold standard. Thirty-six consecutive patients (5 males and 31 females; 18 to 60 years; average age of 31 years) were prospectively investigated with ultrasonography, performing 69 joints (39 with disc displacement with reduction and 30 free of displacements). The exams were accomplished with a 6-12 MHz linear transducer, positioned to obtain static and dynamic images in the coronal and inclined axial plane (Camper’s plane). The diagnosis of disc displacement was established according to objective and measurable criteria, based on two indirect ultrasonographic signals. The first one was the enlargement of the distance between the most anterior point in the joint capsule and the most anterior point in the mandibular condyle (anterior capsule-condyle distance), measured in the static images. The second one was the occurrence of sudden decrease and increase of the anterior capsule-condyle distance, respectively during mandibular opening and closing. Statistic analyzes applying logistic regression indicated occurrence of anterior disc displacement in cases with the anterior capsule-condyle distance higher than 2.2 mm (when sudden decrease and increase were present) and 4.0 mm (when sudden decrease and increase were absent). In the cases with anterior disc displacement with reduction, the measures of the anterior capsule-condyle distance at open-mouth position were smaller than the ones at closed-mouth position and had a tendency to be situated near the averages values of 1.4 mm e 2.4 mm, respectively in the occurrence of total and partial reduction. The suggested ultrasonographic technique for diagnosing anterior disc displacement provided the accuracy of 88.4%, sensibility of 84.6%, specificity of 93.3%, false-positive rate of 5.7% and false-negative rate of 17.6%. We believe that this study can contribute to the use of ultrasonography in temporomandibular disorders, with the presented objective criteria for the diagnosis of disc displacement.

Resumo: A ressonância magnética é o exame de escolha para o estudo das desordens temporomandibulares de disco, considerando-se sua alta definição dos tecidos moles. O objetivo deste estudo foi avaliar a possível relação entre três parâmetros geométricos do músculo pterigóideo lateral (MPL) - o ângulo entre seu longo eixo do e o plano sagital mediano (ANG), seu volume (VOL) e a intensidade do seu sinal (SIN) - e a presença de desarranjos discais (posição e função do disco) em articulações temporomandibulares (ATM) e a presença de dor e ruído articulares, por meio de imagens de ressonância magnética (RM). Foram analisados 39 exames de (RM) (78 ATM) de indivíduos com idades entRe 16 a 71 anos, obtidos em protocolo específico para análise das ATM, pertencentes ao arquivo da disciplina de Radiologia. Foi utilizado o software OnDemand 3D (Cybermed, Seul, Coréia do Sul) para obtenção dos ANG e o software itkSNAP 4.3 (www.itksnap.org) para segmentação do MPL e obtenção de VOL e SIN. A angulação, volume e intensidade do sinal do MPL foram comparados com: posição e função do disco articular, dor articular e presença de ruídos articulares, por meio do teste t de Student, com nível de significância de 5%. Os resultados indicaram que foram encontradas diferenças significativas apenas entre a presença de dor no MPL e sua angulação (p<0,0001), para ambos os lados, não sendo encontradas diferenças significantes para todas as demais variáveis estudadas (p>0,05).

Abstract: Magnetic resonance imaging is the examination of choice for the study of temporomandibular disc disorders, considering its high definition of soft tissues. The objective of this study was to evaluate the possible relationship between three geometric parameters of the lateral pterygoid muscle (LPM) - angle between its long axis and median sagittal plane (ANG), its volume (VOL) and its signal intensity (SIN) - and disc derangements (disc position and disc function) of the temporomandibular joint (TMJ), joint pain. A total of 39 magnetic resonance (MRI) exams (78 TMJ) were analyzed from individuals aged 16 to 71 years, obtained in a specific protocol for the analysis of TMJ, belonging to the archive of the discipline of Radiology. OnDemand 3D software (Cybermed, Seoul, South Korea) was used to obtain ANG and itkSNAP 4.3 software (www.itksnap.org) for LPM segmentation and obtaining VOL and SIN. The LPM angle, volume and signal intensity were compared to: position and function of the articular disc, articular pain and presence of articular noise, using Student's t test, with a level of significance of 5%. The results indicated that significant differences were found only between the presence of LPM pain and its angle (p <0.0001) for both sides, and no significant differences were found for all other variables studied (p> 0.05). It was concluded that, in this sample, a greater value of the sagittal angle of LPM was related to the presence of pain in this muscle group

Aim: To compare osseous changes in the mandibular condyles in patients presenting to the Oral Health Center, Tygerburg Campus, with and without clicking of the temporomandibular joint. Background: Clicking of the temporomandibular joint (TMJ) is not a normal occurrence in its form or function. A chronic click may lead to the development of osteoarthritis. A clinical finding of clicking of the joint can reflect osseous changes of the bony structures and form part of the early signs of degenerative joint diseases. These osseous changes can be detected on Cone Beam Computed Tomography (CBCT) images. The purpose of this study is to confirm the presence osseous changes of the joint and institute the early management of these patients. Failure to intervene in the early stages could result in disease progression to possible osteoarthritis. CBCT imaging will be used to assess osseous changes in the temporomandibular joints with reference to erosions, flattening, lipping, sclerosis and osteophyte formation. Materials and methods: 25 patient records were selected for a control group and 25 patients that attended the Oral Health center were screened for asymptomatic clicking of the temporomandibular joints. Osseous changes of the 100 condyles were examined by the author and a senior member of the department. Changes were recorded when consensus was reached on the presence of any changes. Cone Beam Computed Tomography was used to assess the joints in both groups. Results: Age and gender showed no statistical significance between the 2 groups. The proportion of ‘yes’ for the variables showed that sclerosis (right) was statistically significant when comparing case versus control groups (P = 0.002). A chi-squared test applied to the data resulted in observed chi-square = 15.68, df = 1, p-value = 7.501e-05, (<0.0001) confirming that the discrimination is statistically significant. Conclusion: Osseous changes were found in both the control and case group. The case group exhibited equal or greater prevalence of osseous changes. Patients with asymptomatic click of the temporomandibular joints demonstrate osseous changes.

Le disque de l'articulation temporomandibulaire est un fibrocartilage qui assure la congruence des structures osseuses de l'articulation temporomandibulaire (ATM). C'est un élément crucial de l'ATM et plusieurs pathologies sont liées au disque. Pour mieux comprendre ce tissu mou, six échantillons de disque porcin ont été testés en compression sphérique locale. Le banc de mesure a permis de reproduire les conditions physiologiques, grâce à des condyles imprimés en 3D servant de porte-échantillons, ainsi qu’un environnement d'essai humide à travers une chambre d'essai remplie d'une solution physiologique contrôlée en température et différentes vitesses de chargement pour couvrir la gamme physiologique d'activités de l’articulation. Les essais ont révélé le comportement non-linéaire et visqueux du tissus et les résultats ont permis de constituer une riche base de données. Le banc de mesure a permis de tester les échantillons dans leur intégralité. Cette condition est primordiale car le disque de l'articulation temporomandibulaire est le site de contraintes internes, ce qui a pu être analyser grâce aux déformations résiduelles. De plus, des outils d'interprétation par simulation permettant de définir des lois de comportement adaptées au disque l'articulation temporomandibulaire ont été développés. Par conséquent, une analyse théorique a été effectuée sur la compression sphérique de couches fines enrichie par des simulations par éléments finis. Les courbes de contrainte-déformation résultantes ont conduit à des paramètres constitutifs alimentant des modèles éléments finis tridimensionnels d'essais de compression sphérique sur le disque ATM. En conclusion, ces travaux fournissent des données et des outils conduisant à de larges perspectives de simulation de l'articulation temporomandibulaire qui peuvent être utilisées pour prédire son comportement dans des conditions données
The temporomandibular joint disc is a fibrocartilage that provides congruency of the bony structures of the temporomandibular joint (TMJ). It is a crucial element of the TMJ and several TMJ pathologies are related to the disc. To better understand this soft tissue six porcine TMJ disc samples were tested in local spherical compression tests. The experimental setup included physiological conditions, provided by 3D printed condyles as sample holder, humid test environment using a testing chamber filled with physiological solution at a controlled temperature and different test velocities to cover the physiological range of joint activities. The experiments revealed the non-linear and viscous tissue behaviour leading to the creation of a database. The experimental setup allowed testing the disc samples in its integrity. This is a paramount condition since the TMJ disc is the site of internal strains, which has been shown through residual strain analysis. Furthermore, interpretation tools through simulation allowing defining constitutive laws suitable for the temporomandibular joint disc were developed. Therefore, theoretical analysis has been performed on thin layer spherical compression enriched by finite element analysis simulations. Resulting stress-strain curves led to constitutive parameters feeding three dimensional finite element models of spherical compression tests on the TMJ disc. In conclusion, this work provides data and tools leading to large perspectives regarding simulation of the temporomandibular joint that can be used to predict its behaviour for given conditions

Objective The goal of this project was to define and measure human volumetric airway dimensions with radiographic volumetric three-dimensional imaging and digital reconstruction of the pharynx using cone beam computed tomography to directly correlate these measurements with both normal and developmentally deficient jaw joints and their positions. The volume of the oropharynx was measured by creating a superior border connecting the 3-D midpoint of sella turcica and the posterior nasal spine and extending inferiorly to the level connecting the most infero-anterior point of C3 and the anterior hyoid bone as seen in the multi-planar views of the cone beam computed tomography image. The calculations were accomplished by using 3dMD software. Further extrapolation of this study'a data may be useful to establish the direct association of obstructive sleep apnea and deficiencies of jaw growth and airway development. Design In this retrospective study, 250 subjects were randomly selected from a pool of 800 referred for dental imaging at ddi Imaging Center in Sacramento, California. Digital images were captured using a low-radiation, rapid scanning cone beam computed tomography system (iCAT). Results A total of 250 subjects, 163 females and 87 males, were included in this study. Descriptive statistics were applied to the following variables: 1. Assessment of the relationship between total airway volume and several categorically independent variables: * For total airway volume, no significant difference was found between males and females; between the right temporomandibular positions; between right temporomandibular integrity; or between the left temporomandibular integrity. * There was a significant difference found between the left temporomandibular positions for total airway volume. 2. Assessment of the relationship between total airway volume and each cephalometric measurement: * Based on the Spearman correlation test, there were significant increasing relationships between total airway volume and several of the cephalometric measurements (p<0.05). * Correlation coefficients ranged from 0.13 to 0.22 indicating there were weak correlations between the two variables. 3. Assessment of the relationship between total airway volume and age: * Based on the Spearman correlation test, there was no significant relationship between total airway volume and age (p=0.8304). In addition, Spearman correlation showed no correlation between total airway volume and sex and skeletal growth pattern tendencies. Conclusions Three dimensional images of the airway offer the opportunity to serially examine individuals, acquire airway patency information, and improve the evaluation of sites of airway obstruction. Further studies to determine the effects of pharyngeal stenosis and other regional changes to the oropharynx upon physiologic response may be key to understanding the effects of biomechanical influences upon craniofacial form. Comprehension of structural inter-relationships will also help develop an understanding of how and why adaptive changes in airway shape and volume occur. Airway patency is related to many variables: head posture, the direction of mandibular rotation during growth and development, and hyoid bone position. Further studies may offer an increased understanding of these structural and positional interrelationships.

Resumo: Desordem Temporomandibular (DTM) é um termo utilizado para determinar as condições de patologias clínicas que envolvem os músculos mastigatórios e articulações temporomandibulares (ATM). Ocorre freqüentemente entre as mulheres em idade fértil, aumentando a prevalência após a puberdade e diminuindo na pós-menopausa, o que sugere uma correlação com os hormônios reprodutivos, principalmente o estrógeno. O objetivo deste trabalho foi correlacionar a freqüência de dois polimorfismos do gene receptor a. de estrógeno (Pvu " no intron 1 e Xba I no intron 1), com a presença de sinais e percepção de dor relacionados aos desarranjos interno da articulação temporomandibular (DI/ATM) em mulheres da região de Piracicaba, Brasil. Para tanto foram analisados os polimorfismos genéticos em 300 pacientes do sexo feminino com idade variando entre 18-45 anos, divididos em três grupos segundo análise feita através do exame RDCITMD: grupo controle composto por 100 voluntárias que não apresentavam DTM; grupo experimental 1, composto por 100 voluntárias portadoras de DI/A TM e presença de dor; grupo experimental 2, composto por 100 voluntárias portadoras de DI/A TM e com ausência de dor. A obtenção do ácido desoxirribunucleico (DNA) das voluntárias foi feita através de células epiteliais da mucosa bucal obtidas por bocheco de glicose 2% I e posteriormente foi amplificado pela reação de PCR (polimerase chain reaction). Para a identificação dos alelos foi realizada a técnica de RFLP (restriction fragment length polymorphism), na qual os fragmentos amplificados foram submetidos à digestão por enzimas de restrição. Finalmente, o produto do RFLP foi submetido à eletroforese em géis de poliacrilamida a 10%, que posteriormente foram corados pela técnica da prata. Foram utilizados primers para determinar as condições de amplificação e restrição dos polimorfismos genéticos que foram estudados. A análise estatística foi realizada utilizando o teste x² (significância de 5%), e o teste de Odds Ratio (OR) foi usado para avaliar o risco das pacientes apresentarem dor. Não houve diferença estatística significante na distribuição dos alelos do polimorfismo Xbal (A-357G) e Pvull (T-391 C). No entanto houve diferença significativa para o sítio polimórfico (A-357G) quanto à distribuição genotipica entre as voluntárias portadoras de DI/ATM com dor e o grupo controle (p=O,03). O teste OR (PAbstract: Temporomandibular disorders are common pain conditions that have the highest prevalence among women of reproductive age. The pattern of onset afier puberty and lowered prevalence rates in the postmenopausal years suggest that female reproductive hormones may play an etiologic role in temporomandibular disorder OBJECTIVES: The purpose of the present study was to analyze the association between two polymorphisms (Pvu 11 in intron 1 and Xba I in intron 1) and signal and symptoms of internal disarrangements of Temporomandibular Joint (IOTMJ) in Brazilian women. MATERIAL AND METHODS: Tree hundred women volunteers, 18-45 years old, not taking contraceptive, was selectioned throughout Research Diagnostic Criteria for Temporomandibular Disorders (RDCITMO) and divided in: Control group: 100 women without signal and symptoms related to IDTMJ; Test Group 1 - 100 women with symptoms but without pain related to IDTMJ and Test Group 2 - 100 women with symptoms and pain related to IDTMJ. Genomic DNA from buccal mucosa was amplified by the polymerase chain reaction (PCR), followed by restriction fragment length polymorphism (RFLP) and submitted to polyacrylamide gel electrophoresis to distinguish the alleles. Differences in the allele and genotype frequencies between control and test groups were assessed by chi (2) test (P<0.05). And the risk of pain in women was assessed by Odds Ratio test (p<0.05). RESUL TS: No statistically significant differences were found in the aliei e distribution. Nevertheless, Xbal polymorphic site was significantly different to genotype distribution between TMO with pain and control group (p=0.03). The GG genotype seemed to increase susceptibility to have pain in women (odds ratio (OR) =2.55). CONCLUSION: This study suggests that GG presence in the estrogen receptor a (A-357G) polymorphism is associated with pain in Brazilian women with ID/TMJ and was not conclusive with the higher prevalence of this disease in Brazilian women
