Individuals with temporomandibular disorders (TMD) often have signs and symptoms such as intra-articular pain, muscle spasm, neck pain radiating from others who interfere with this balance. Over time can lead to postural changes and correction of the cervical spine, anterior head and shoulder asymmetry. The aim was to verify the effects of manual therapy on posture in subjects with TMD. Materials and methods: 30 volunteers (mean: 21.43± SD:1.43) of both sexes who had TMD classified according to axis I of the Research Diagnostic Criteria participated in this study. These were photographed in the anterior frontal and sagittal planes for analysis of the following angles (acromion clavicular joint, sternoclavicular joint, orbicular external, corners of the mouthand and protruding head). After, the volunteers were divided into groups ATM (manual therapy in the treatment of temporomandibular joint), Cervical (manual therapy in the treatment of cervical joint) and Control. The Kolmogokov-Smirnov test, followed by ANOVA, considering a significance level of 5% was used. Results: Groups ATM, Cervical and Control were considered homogeneous with respect to the values of the angles measured. These also showed no significant difference between the 1st, 5th and 10th sessions, so the manual therapy techniques applied to the TMJ and Cervical groups were not sufficient to change postural alignment. Conclusion: The postural alignment, the TMD patients evaluated in this study did not change after attending the sessions proposals with manual therapy techniques in the cervical and TMJ.

INTRODUCTION: Temporomandibular disorders (TMD) have association with psychological manifestations. OBJECTIVE: The aims of this study were to correlate the severity of TMD and the level of self-esteem, and to investigate sex‑related differences. MATERIAL AND METHOD: We evaluated 57 subjects of both gender, with mean age of 20.28 ± 2.07 years, through the Fonseca Anamnesis Index (FAI) and Rosenberg Self-esteem Scale (RSS). Correlations between variables were performed using the Spearman correlation coefficient; comparisons between the genders were performed using the Mann-Whitney test. It was considered a significance level of 5%. RESULT: No differences were found for the comparisons between the gender in the FAI (p = 0.79) and the RSS (p = 0.90). RSS correlates with the FAI in women (p = 0.01), but in men this result does not occur (p = 0.07). CONCLUSION: We concluded that women are more likely to have emotional disturbances resulting from changes in the temporomandibular joint than men.

JUSTIFICATIVA E OBJETIVOS: A disfunção temporomandibular (DTM) é um termo que descreve um grupo de doenças que afetam funcionalmente o aparelho mastigatório, particularmente a musculatura mastigatória e a articulação temporomandibular (ATM). Tem etiologias múltiplas e tratamentos específicos, entre os quais a estimulação elétrica nervosa transcutânea (TENS). O objetivo deste artigo é o de revisar a literatura científica sobre o uso da TENS em pacientes com DTM. CONTEÚDO: Estudos epidemiológicos mostram que aproximadamente 75% da população apresentam algum sinal de DTM, enquanto 33% possuem ao menos um sintoma. Sempre que possível deve-se tratar a causa da dor, caso não se consiga estabelecer a sua etiologia, inicia-se com procedimentos menos invasivos e reversíveis, especialmente nos casos de dor e disfunção muscular. A terapia com TENS consiste na administração de corrente elétrica na superfície cutânea, de modo a relaxar os músculos hiperativos e promover o alívio da dor. CONCLUSÃO: Embora existam controvérsias quanto ao uso de TENS para o controle da dor crônica, seu uso na dor muscular mastigatória continua relevante. Entretanto, é fundamental o diagnóstico preciso para evitar uso inadequado. São necessários ainda estudos randomizados controlados que incluam amostras selecionadas para homogeneizar o uso de TENS em pacientes com DTM.

OBJETIVO: revisar a literatura mais atual, dos últimos 15 anos, em busca de estudos clínicos que relatem a relação entre a disfunção temporomandibular (DTM) e o tratamento ortodôntico e/ou a má oclusão. A intenção foi verificar se o tratamento ortodôntico aumentaria o aparecimento de sinais e sintomas de DTM, e se o tratamento ortodôntico seria um recurso para o tratamento ou prevenção dos sinais e sintomas de DTM. MÉTODOS: artigos dos tipos revisão de literatura, editorial, carta, estudo experimental em animais e comunicação foram excluídos dessa revisão. Foram incluídos artigos prospectivos, longitudinais, caso-controle ou retrospectivo com amostra maior, com relevante análise estatística. Estudos que abordassem deformidades e síndromes craniofaciais e tratamento por cirurgia ortognática também foram excluídos, bem como aqueles que relatassem apenas a associação entre má oclusão e DTM. RESULTADOS: foram encontrados 20 artigos relacionando Ortodontia à DTM, segundo os critérios adotados. Os estudos, então, associando sinais e sintomas de DTM ao tratamento ortodôntico apresentaram resultados heterogêneos. Alguns encontraram efeitos positivos do tratamento ortodôntico para os sinais e sintomas de DTM; entretanto, nenhum deles apresentou diferença estatisticamente significativa. CONCLUSÕES: todos os estudos citados nessa revisão de literatura relataram que o tratamento ortodôntico não forneceu risco ao desenvolvimento de sinais e sintomas de DTM, independentemente da técnica utilizada para tratamento, da exodontia ou não de pré-molares e do tipo de má oclusão previamente apresentada pelo paciente. Alguns estudos realizados com acompanhamento em longo prazo concluíram que o tratamento ortodôntico não seria preventivo ou uma modalidade de tratamento para DTM.

We surveyed subjective symptoms of 600 patients referred to the Occlusion and Craniomandibular Dysfunction Center of the School of Dentistry, Campus of São José dos Campos São Paulo, Brazil. We have only considered those symptoms reported by the patients as major complaints. Our purpose on this project was to draw a profile of the disease considering sex, age and incidence of the symptoms that presented themselves or associated with others. Findings were that we found a significant larger number of women, 82.83%, comparing with 17.17% of men. Most of the patients belonged to the third decade, followed by the fourth and second. The most frequent symptom was pain on TMJ region, 42%, followed by TMJ noises, 26.6%, facial pain, 15.5%, earache, 14.5% and headache, 12.1%. The symptom TMJ noises showed to be statistically more significant in men, while headaches, pain in the neck region and temporary locking were more frequent in women. The most frequent association between two symptoms was: TMJ noises with TMJ pain, earache with headache and TMJ pain with earache. There was no statistical difference between sexes. The most frequent association of three symptoms was: TMJ noises together with TMJ pain and pain or difficulty in chewing

One hundred non-patient dentistry students aged 17 to 25, were interviewed through questionnaire and were clinically examined in order to asses the prevalence and degree of severtty of Craniomandibular Dysfunction, through indeces which are subdivided into three classes: anaminestic index, clinical dysfunction index, and occlusal index. The following variables were introduced to the original indeces: sex, age, and whether the subjects had or had not received orthodontic treatment. The results showed that 42% of the subjects presented mild subjective symptoms whereas, no one showed severe subjective symptoms. Women, as well as the older subjects, showed a higher trend to presenting more subjective complaints. Subjects, whether treated orthodontically or not, showed a similar trend to having dysfunction symptoms. Fifty-six per cent of the subjects presented some score of clinical dysfunction, 25% of them showed moderate or severe clinical dysfunction. Women showed a statistically significant higher index. The older subjects trented to have indeces with more severe degrees. Orthodontic treatment suggested to have no influence on the clinical dysfunction index. Sixty-six per cent of the subjects showed a mild occlusal index and 11% a severe occlusal index. Sex, age, and orthodontic treatment did not show any significant difference as to the presence or absence of malocclusion

Purpose: due to the presence of major masticatory dysfunction in patients with temporomandibular joint (TMJ) ankylosis, this study analyzed mouth opening and EMG activity of masticatory muscles in order to detect changes in these parameters after surgical release of mandible ankylosis. Method: in 7 patients with temporomandibular ankylosis, between 7 and 30 years (median = 9 years), the distance was measured as interincisal maximum active (DIMA) and we recorded the electromyographic activity (EMG) of masseter and temporal muscles during voluntary isometric contraction (VIC) and chewing, comparing the data before and after surgery using the Wilcoxon test. Results: higher values were observed for DIMA after surgery (p=0.0277), the asymmetry index showed no difference between the two evaluated periods for both studied muscles, the values of the EMG during VIC decreased after surgery for the right (p=0.0179) and left (p=0.0179) masseter but not for the temporal muscle, there were no changes in EMG values for the studied muscles during mastication. Conclusion: the surgical release of TMJ ankylosis resulted in an increase of mouth opening and decreased amplitude of action potentials generated during maximum isometric voluntary contraction of the masseter muscle on both sides, this did not change the asymmetry index of the masseter and temporal as well as the electromyographic activity of the temporal muscle bilaterally during isometric contraction and masseter and temporal muscles during mastication.

Temporomandibular joint (TMJ) sounds are important and common physical signs of temporomandibular disorders (TMD). The aim of this study was to evaluate the influence of the effect of the use of occlusal bite splints (stabilizing and repositioning) on the sounds produced in the TMJ, by means of the electrovibratography (EVG). Thirty-one patients with TMD from the Dental School of Ribeirão Preto, University of São Paulo, Brazil were selected for this study. Group 1 (n=23) wore stabilizing bite splints and Group 2 (n=8) used anterior repositioning splints. Before and after treatment with occlusal splints both groups were analyzed using the SonoPAK Q/S recording system (BioResearch System, Inc.). The treatments with stabilizing bite splints were satisfactory, since they reduced the total amount of the sound energies (p<0.05), but the use of anterior repositioning splints for no more than 4 weeks produced significantly better results (p<0.01). The total amount of vibration energy involved in the vibrating movements of the TMJ showed significant improvement using anterior repositioning splints.

PURPOSE: Juvenile idiopathic arthritis (JIA) has unknown etiology, and the involvement of the temporomandibular joint (TMJ) is rare in the early phase of the disease. The present article describes the use of computed tomography (CT) and magnetic resonance (MRI) images for the diagnosis of affected TMJ in JIA. CASE DESCRIPTION: A 12-year-old, female, Caucasian patient, with systemic rheumathoid arthritis and involvement of multiple joints was referred to the Imaging Center for TMJ assessment. The patient reported TMJ pain and limited opening of the mouth. The helical CT examination of the TMJ region showed asymmetric mandibular condyles, erosion of the right condyle and osteophyte-like formation. The MRI examination showed erosion of the right mandibular condyle, osteophytes, displacement without reduction and disruption of the articular disc. CONCLUSION: The disorders of the TMJ as a consequence of JIA must be carefully assessed by modern imaging methods such as CT and MRI. CT is very useful for the evaluation of discrete bone changes, which are not identified by conventional radiographs in the early phase of JIA. MRI allows the evaluation of soft tissues, the identification of acute articular inflammation and the differentiation between pannus and synovial hypertrophy.

Os sintomas otológicos são freqüentes em pacientes com desordem temporomandibular, e estudos são necessários para elucidar os mecanismos envolvidos. OBJETIVO: O objetivo desse estudo clínico foi investigar a associação de sintomas otológicos (otalgia, zumbido e plenitude auricular) com os achados audiológicos, os outros sinais/sintomas relacionados à desordem temporomandibular, e os hábitos parafuncionais orais. FORMA DE ESTUDO: Prospectivo clínico. MATERIAL E MÉTODO: 27 pacientes com desordem temporomandibular, da Clínica de Oclusão da Faculdade de Odontologia de Ribeirão Preto da Universidade de São Paulo, responderam um questionário sobre sinais, sintomas e hábitos orais, e passaram por avaliações otorrinolaringológica e audiológica. Os dados foram analisados pelos testes Binomial, Exato de Fisher e correlação produto-momento de Pearson. O índice de significância adotado foi p<0,05. RESULTADOS: Os sintomas otológicos foram presentes em 88,88% dos pacientes (59,26% apresentavam otalgia, 74,07% zumbido e 74,07% plenitude auricular). Não houve associação significante entre os sintomas otológicos e os achados audiológicos. Houve associação significante entre os sintomas otológicos e os movimentos mandibulares e funções (falar, abrir e fechar a boca). Houve também correlações significantes entre o grau de severidade dos sintomas otológicos e o grau de outros sinais/sintomas de desordem temporomandibular; e entre o sintoma plenitude auricular e número de hábitos parafuncionais. CONCLUSÃO: Este estudo fornece sustentação adicional à noção de que há relação entre desordem temporomandibular e sintomas otológicos. Nos pacientes com desordem temporomandibular as alterações do sistema estomatognático, como a dor orofacial e a dificuldade nas atividades funcionais, foi associada de modo significante aos sintomas otológicos.

A interação entre disfunção temporomandibular e otalgia é, mesmo nos dias atuais, motivo para especulações e hipóteses. Vários pesquisadores sugerem causas, conseqüências e supostos tratamentos. OBJETIVO: Verificar a prevalência de pacientes portadores de DTM em um serviço de otorrinolaringologia. TIPO DE ESTUDO: Este é um estudo epidemiológico do tipo descritivo com amostra transversal. MATERIAL E MÉTODO: Foram avaliados 221 pacientes do Serviço de Otorrinolaringologia do Hospital da Cidade, em Passo Fundo, Rio Grande do Sul, durante um período de dois meses. Para captação e interpretação dos dados, bem como verificação da disfunção temporomandibular, foi utilizado um questionário auto-aplicado previamente validado. RESULTADO: Após coleta e interpretação dos dados de 221 pacientes, os resultados obtidos foram: 48 pacientes (21.72%) considerados como necessitando de tratamento para DTM (índice de DTM moderada e severa), dos quais 35 pertenciam ao gênero feminino (72.9%) e 13 ao masculino (21.1%). Apenas 15 indivíduos do total (7.24%) estavam totalmente livres de sintomas de DTM. Quanto aos demais, apresentaram: dor de cabeça (33,5%), dor no pescoço e ombro (28,5%), dor na região do ouvido (29%) e ruídos articulares (25%). CONCLUSÃO: A prevalência de DTM foi de 21.72% sendo significantemente maior no gênero feminino (p: 0.0001); e as prevalências, em relação aos índices, foram: DTM ausente 37.56%; DTM leve 40.72%; DTM moderada 19%, e DTM severa 2.72%.
