“…Several large observational studies have linked various occlusal traits with the signs and symptoms of temporomandibular joint disorders, including crossbites, anterior openbite and increased overjets; 10,12 however these are based on weak correlations, which in themselves do not prove causation. This is in part because temporomandibular joint disorders represent a complex, poorly understood, collection of conditions, with a multifactorial aetiology.…”

SummaryOrthodontic treatment is as popular as ever. Orthodontists frequently have long lists of people wanting treatment and the cost to the NHS in England was £261m in 2013-14 (approximately 11% of the NHS annual spend on dentistry). It is important that clinicians and healthcare commissioners constantly question the contribution of interventions towards improving the health of the population. In this article the authors outline some of the evidence for and against the claims that people with a malocclusion are at a disadvantage compared with those without a malocclusion and that orthodontic treatment has significant health benefits. The authors would like to point out that this is not a comprehensive and systematic review of the entire scientific literature. Rather the evidence is presented in order to stimulate discussion and debate.

“…29 The cone-beam tomography has a relevant importance in diagnosis, localization and reconstruction of tomographic images with excellent precision, aiding in therapeutic decisions. 4 Clinically, the scientific evidences indicate for a tendency of no association between orthodontic treatment and temporomandibular disorders (TMD), in other words, orthodontics does not increase the prevalence of signs and symptoms of TMD, with longitudinal and experimental-interventionist studies, 7,8,[13][14][15][16]25 systematic review 24 and meta-analysis 18 corroborating that. Also, with the analysis of imaging studies, according to the methodological criteria adopted by this systematic review, it appears that orthodontic movement does not cause adverse effects to the TMJ.…”

INTRODUÇÃO: a evolução da Imaginologia na Odontologia propiciou uma série de vantagens para o diagnóstico e elaboração de planos de tratamento em diversas especialidades. Exames como ressonância magnética nuclear, tomografia computadorizada e tomografia volumétrica Cone Beam, bem como métodos de reconstrução em 3D, permitiram analisar de forma precisa estruturas orofaciais.Aliado a esse fato,com a realização de estudos clínicos com metodologias e desenhos adequados, pode-se avaliar os efeitos do tratamento ortodôntico sobre a articulação temporomandibular (ATM). OBJETIVO: esse trabalho, através de uma revisão sistemática de literatura, teve como objetivo analisar a inter-relação entre o tratamento ortodôntico e a ATM, verificando se a Ortodontia acarreta alguma alteração das estruturas internas da ATM. MÉTODOS: levantamento em bases de pesquisa (MEDLINE, Cochrane, EMBASE, Pubmed, Lilacs e BBO), entre os anos de 1966 e 2009, com enfoque em estudos clínicos randomizados, estudos longitudinais prospectivos não randomizados, revisões sistemáticas e meta-análises. RESULTADOS: após a aplicação dos critérios de inclusão, chegou-se a 14 artigos, sendo que 2 eram estudos clínicos randomizados e 12 eram estudos longitudinais sem critérios de randomização. CONCLUSÕES: pela análise da literatura, conclui-se que a realização do tratamento ortodôntico não ocorre à custa de posicionamentos não fisiológicos do côndilo e disco articular. Algumas mecânicas podem acarretar remodelações dos componentes ósseos articulares.

“…Currently, there is a consensus among researchers and specialists that occlusion should not be viewed as a major factor in the cause of TMD [5][6][7][8]20,25 but instead should be viewed more as one of several factors that may be related to it. However, it can be observed from the CG group that most DSs still take the occlusionist theory for granted [2][3][4] , with statistically significant differences from the EG group.…”

“…The relationship between orthodontic treatment and TMD, whether as prevention, treatment, or cause, has been widely discussed over the years, and today, malocclusion correction is not considered to be a method of treating this disorder 6,10,12,13,15 . However, many CG group participants still believed in the strong role of orthodontics and occlusal adjustment, which may be related to their belief that occlusal factors are primarily responsible for the disorder.…”

“…Recent studies, however, have revealed an inconsistent relationship between occlusal factors and the presence of the signs and symptoms of TMD [5][6][7][8] . Current scientific evidence suggests that these disorders have a multifactorial nature that is associated with several factors, such as muscle hyperactivity, trauma, emotional stress, and parafunctional and numerous other predisposing, precipitating, and perpetuating habits 1,2,4,9,10 .…”

ResumoIntrodução: A relação da oclusão dentária com a Disfunção Temporomandibular (DTM) ainda gera divergências. Muitos profissionais erroneamente baseiam o diagnóstico e a terapia estritamente no fator oclusal, apesar das evidências científicas atuais não mostrarem tal relação. Objetivo: Avaliar o conhecimento dos cirurgiões-dentistas (CDs) de João Pessoa-PB, acerca da relação entre fatores oclusais e DTM. Material e método: Uma amostra de 100 CDs que não possuem especialização em DTM e Dor Orofacial (Grupo GN), além de sete CDs com essa especialidade (Grupo GE) preencheram questionário abordando assuntos relativos ao conhecimento da DTM e sua relação com fatores oclusais. O questionário continha também informações para caracterização da amostra como idade, gênero e tempo de formado. O grau de consenso da literatura atual para cada sentença foi estabelecido como "padrão-ouro" de resposta, o qual foi comparado com as respostas dos especialistas e não especialistas. Os dados foram tabulados no programa SPSS e analisados de forma descritiva (através de porcentagens) e, estatística, por meio dos testes Qui-quadrado e Exato de Fisher (p<0,05). Resultado: Observou-se grande divergência no conhecimento dos cirurgiões-dentistas sem especialidade em DTM e Dor Orofacial com os profissionais dessa especialidade. Conclusão: Houve baixa concordância entre os especialistas e não especialistas. A relação entre oclusão dentária e disfunção temporomandibular ainda permanece obscura para a grande maioria dos profissionais entrevistados, o que pode vir a se refletir em condutas de diagnóstico e tratamento oclusal inadequadas para o manejo das DTM.Descritores: Oclusão dentária; síndrome da disfunção da articulação temporomandibular; conhecimento. Abstract Introduction:The relationship between dental occlusion and temporomandibular disorders (TMD) remains a subject of disagreement. Many professionals erroneously base diagnosis and treatment strictly on the occlusal factor, despite the fact that current scientific evidence does not show such a relationship. Objective: To evaluate the knowledge of dental surgeons (DSs) from João Pessoa (PB)-Brazil, regarding the relationship between occlusal factors and TMD. Materials and method: A sample of 100 DSs who do not have expertise in TMD and orofacial pain (CG Group) and seven DSs with this specialty (EG Group) completed a questionnaire that addresses issues concerning knowledge of TMD and its relationship with occlusal factors. The questionnaire also contained information used to characterize the sample, such as age, gender, and length of experience. The current literature's degree of consensus was established as the "gold standard" response for each statement and was compared with the responses of the specialists and non-specialists. Data were tabulated using the SPSS software package and analyzed descriptively (by percentage) and statistically using the chi-square and Fisher's exact tests (p < 0.05). Result: A wide divergence could be observed between the knowledge of DSs who do not spe...

TMD in Relation to Malocclusion and Orthodontic Treatment

Abstract: Associations between specific types of malocclusions and development of significant signs and symptoms of TMD could not be verified. There is still a need for longitudinal studies.
