Abstract
ABSTRACT Objective: to evaluate the prevalence of temporomandibular joint disorder in people with Parkinson’s disease in a public university hospital, and relate it to sociodemographic factors, general health and oral health self-report, and phase and time of illness. Methods: the Research Diagnostic Criteria for Temporomandibular Disorders were used. The sample was classified according to the diagnosis of temporomandibular disorder and associated with the variables. The odds ratio of Chi-square was applied with a 95% confidence interval and a level of significance set at p<0.05. Results: 110 people presented with Parkinson's disease were assessed. The prevalence of temporomandibular disorder was 35%, being more frequent among males (58%), in elderly people (53%), in phase 2 of the disease (61%), click (37%) being the predominant clinical indication. Of the variables analyzed, only gender and self-perception of oral health showed to be associated with temporomandibular disorders. Conclusion: the presence of temporomandibular disorder has been observed in people with Parkinson's disease, and the fact of being male and reporting moderate oral health seen as associated factors.

Exclusion criteria were: people with other neurologic diseases associated with Parkinson’s disease; people with compromised cognition, as evaluated by the Mini-Mental State Examination (MMSE); and people lacking their teeth on both dental arches

Summary
The temporomandibular joints (TMJ) are considered to be one of the most complex in the human body. As for the multifactorial etiology, temporomandibular disorder (TMD) is related to anatomic and neuromuscular aspects, as well as parafunctional habits, postural deviations, traumas and psychosocial changes. It causes a range of conditions and symptoms, such as pain in the muscles of mastication and TMJ, presence of noise and joint deviation, headache, hearing disorders, sensibility all over the muscles of the cervical and stomatognathic system[2]. These characteristics vary from person to person, whose quality of life is negatively affected by their presence. The person’s physiological and structural tolerance is the aspect that will determine whether they will develop the disorder[2]
