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.
