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.

The authors emphasize the some functional characteristics of the Temporomandibular join, TMJ, and were made comparative study of the auscultatory and sphymografic techniques to TMJ examination. The findings shown that the auscultatory technique furnished important dates to preliminary diagnosis of the TMJ disfunction.

Anamnesis, clinical examinations and temporomandibular joint transcraneal radiographs for 22 adults with cleft lip and palate were carried out in order to evaluate the occlusion and correlate it with radographic findings. The conclusions were: 72.8% of the patients have at least one sign or symptom of craniomandibular disorders (CMD); although the occlusal conditions were severely altered, most of the signs and symptoms were classified as mild; the greater frequency of the signs and symptoms occurred among women; in the radiographic evaluation, all of the assymptomatic patients had both condyles with normal contour and all of the patients with altered contour had at least one sign or symptom; the bilateral centered position of the condyles in the fossa e did not warrant the absence of signs and symptoms; some patients with bilateral condyles positioned posteriorly or caudally or even assimetrically, did not present signs and symptoms of dysfunction; the radiographic findings should be correlated with clinical findings; and a great number of patients were not observed with clinical board of C:MD caused by the occlusion. Key words: Radiography; temporomandibular joint; temporomandibular joint syndrome; cleft palate; dental occlusion

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.

This study gathered some of the most relevant researches already undertaken regarding the Temporomandibular Joint, presenting descriptions of its anatomy and dynamics, and relating them to the main aspects of joint dysfunctions. Literature recognizes that the Temporomandibular Joint, responsible for lower jaw movements, comprehends the skull base and the jaw bone. Its anatomy and dynamics are of great importance in order to understand the functions of Stomatognathic System as well as to study Temporomandibular Joint Dysfunction. The elements that compose this synovial joint and the bilateral characteristic confer eminent importance to the ATM before the skeleton head, the ability to perform broad movements and high complexity in its operation. It is accepted that the overload of one anatomical structure from the TMJ or other components of the Stomatognathic System leads to Temporomandibular Joint Dysfunctions. These disorders have different etiologies, ranging from malocclusion to emotional stress, and various forms of treatment, which are related in this study

Class II malocclusion features a high prevalence in Brazil, being considered as a routine in orthodontic clinics. A number of appliances are shown in the literature in order to correct Class II malocclusion with mandibular retrusion. Herbst´s fixed functional appliance, idealized by Emil Herbst (1905) and reintroduced, in the 1980´s, by Hans Pancherz is highlighted for maintaining the mandible continuously advanced, showing a shorter active treament time, an immediate esthetic impact on the facial profile, as well as requiring no patient´s commitment. Recent researches indicate the use of this appliance in individuals after pubertal growth surge. The aim of the present study is to show the orthodontics practitioner the option to use this appliance so as to treat Class II in individuals after the growth surge, obtaining satisfactory outcomes and further Class II correction.
