Pain, click and crepitation as factors associated with temporomandibular dysfunction in Parkinson’s disease

ABSTRACT BACKGROUND AND OBJECTIVES: Parkinson’s disease leads to mandibular movements that affect the masticatory cycle and induce orofacial pain, one of the main clinical alterations found in temporomandibular dysfunction. Thus, the present study aimed to analyze the possible factors associated with temporomandibular dysfunction and to verify the frequency of the dysfunction in this population. METHODS: This was a cross-sectional study in which the participants were evaluated using the Diagnostic Criteria for Temporomandibular Dysfunction research, used to classify the temporomandibular dysfunction and to obtain by physical examination and self-report the variables studied. RESULTS: A total of 139 people with Parkinson’s disease were evaluated. Of these, 77 met the eligibility criteria, with 70% of the sample being male, with an average age of 62±9 years; Parkinson’s disease diagnosis time of 6±4 years and with 71% of the sample in the moderate stage of Parkinson’s disease. No significant associations were found between age, gender, time and stage of the disease with temporomandibular dysfunction. Of the variables analyzed, the significant results showed that the presence of pain (OR=10.92, 95% CI=2.25-59.93, p<0.001) has a greater chance of developing temporomandibular dysfunction, crepitation (Kappa=0.34, p<0.004) reflects moderate accuracy in the classification of temporomandibular joint disorder and the click (negative predictive value=77%, p<0.032) increases the probability of having temporomandibular dysfunction. CONCLUSION: Therefore, in this study, the frequency of the temporomandibular dysfunction was 30%, and it was observed that the factors associated with the dysfunction in people with Parkinson’s disease were: pain, click, and crackle.
