Even though bruxism and Parkinson’s disease have much in common, a possible relationship between them has not been established. The aim of this study was to gain more insight into a possible relationship between bruxism and temporomandibular disorders on the one hand and Parkinson’s disease on the other. For this study, 708 people (368 with Parkinson’s disease or parkinsonism and 340 controls) fully completed a questionnaire. The questionnaire included a selective Dutch translation of the questions from the Diagnostic Criteria for TMD (DC/TMD), complemented with a question about tooth wear. The chi-square test and independent samples t test were used for the data analysis. The results showed patients with Parkinson’s disease or parkinsonism reported pain resulting from temporomandibular disorders and bruxism when asleep and awake significantly more often than the controls. When facial pain was reported, patients with Parkinson’s disease or parkinsonism had a higher mean pain score than the controls. In conclusion, this study showed a relationship between Parkinson’s disease or parkinsonism on the one hand and bruxism on the other. Furthermore, the study revealed a relationship between Parkinson’s disease or parkinsonism on the one hand and pain resulting from temporomandibular disorders on the other.
