• Abstract:

  Temporomandibular disorders (TMD) are a set of joint and muscle disorders in the orofacial region, characterized mainly by pain, limitation of mandibular movement and joint noises, the latter being the first sign of alteration in the joint. The objectives of this study are to verify the prevalence of joint noises in a population with TMD and to verify a possible association of joint noises with occlusal and mandibular functional parameters. The sample consisted of patients who sought treatment at the Faculty of Dentistry of the Universidade do Estado do Rio de Janeiro seeking treatment for TMD in 2016. The patients answered a questionnaire and underwent a clinical examination, according to the RDC/TMD (Research Diagnostic Criteria for Temporomandibular Disorders). The association between each of the parameters evaluated and the presence of joint noise was verified by Fisher's exact test and by the Mann-Whitney test (significance level of 0.05). Thirty-six patients participated in this study, 30 (83.3%) were female and 6 (16.7%) were male. The mean age was 43.58 ± 13.89 years. Twenty-seven patients had some TMJ noise, which corresponded to 75% of the sample examined. Of these, 18 (66.7%) had bilateral noise and 9 (33.3%) had unilateral noise. Click was the most predominant type of noise, observed in 17 (63%) patients with joint noise, and crepitus was observed in 10 (37%) of these patients. No association was found between the presence of joint noises and age, sex, mouth opening limitation, maximum mouth opening, overjet, midline deviation, mouth opening pattern, TMJ pain on palpation or bruxism.
