Orofacial Myofunctional Disorder In Subjects with Temporomandibular Disorder

Abstract

To determine the frequency and degree of orofacial myofunctional disorder (OMD) in a sample of patients with temporomandibular disorder (TMD), the dental records of 240 patients with a diagnosis of TMD were reviewed. Mean patient age and mean TMD duration, gender frequency, complaints, and signs and symptoms were calculated. The results showed that the sample studied was quite characteristic of a TMD group. The presence of the following signs/symptoms was significant: muscular pain, TMJ pain, joint noise, at least one otologic symptom, headache, and neck and shoulder pain. Most subjects presented some degree of OMD, with grade high prevailing over grade low. The importance of evaluating the stomatognathic structures and functions during the clinical examination of patients with TMD is emphasized.

Sinais e sintomas de desordem temporomandibular em mulheres e homens

“…In this study, joint noise, which might indicate dislocation of the joint disk or alterations in the TMJ form, was seen in both genders with the same frequency, as previously verified (12) . The long duration of TMD symptomatology verified in this sample is also an aspect to be considered, because signs and symptoms such as muscle pain, TMJ pain, and joint noise, are not only TMD manifestations, but they can also worsen with time, due to the need of adaptations or compensations that involve the musculature and stomatognathic functions (28) . The TMD average duration was similar between the male and female groups and no statistical difference was found between them for functional difficulties (difficulty to chew, swallow, and speak) or limitation of the mouth opening.…”

Autopercepção da mastigação e fatores associados em adultos brasileiros

“…A mastigação é uma das funções mais importantes do sistema estomatognático por relacionar-se à nutrição, ao crescimento e ao desenvolvimento craniofacial, à maturação da musculatura orofacial, à estabilidade oclusal e à estabilidade da articulação temporomandibular 1,2,3,4 . O padrão e a habilidade mastigatória podem ser influenciados por disfunções temporomandibulares, dor, distúrbios miofuncionais orofaciais, má oclusão, perdas dentárias, uso de próteses mal adaptadas, presença de cárie e/ou doença periodontal 1,2,3,4,5,6 .…”

As dificuldades de mastigação, deglutição e/ou fala podem acarretar um quadro de incapacidade bucal transitória ou permanente com grau, abrangência e evolução variando de indivíduo para indivíduo, segundo o tempo, as características clínicas, as possibilidades terapêuticas e a inserção social 6,7,8,9,10 .…”

Avaliação videofluoroscópica da mastigação e deglutição em indivíduos com disfunção temporomandibular (DTM)

“…Such technique also enables the finding of compensatory movements during chewing, arising from the TMD 6 . The scientific literature has reports on alterations in tongue position and the presence of compensatory neck movements to aid mastication in TMD patients 7 , calling the attention of healthcare professionals concerning the presence of choking during mastication and deglutition 8,9 . Insofar as the assessment of mastication goes, studies have recorded the presence of unbalance in the chewing muscles, in which there is only one side working (chewing), requiring changes in food consistence, and pain during the execution of such task 10,11 .…”
