OBJECTIVES: To characterize orofacial myofunctional structures of elders with Parkinson's disease (PD) and examine the relationship with the stages of PD, pharmacotherapy, and quality of life. METHODS: PD Group with 45 elders and a control group (CG) of 10 healthy elders of both sexes were included (60-86 years). Structured interviews, medical records, and clinical examination gathered information on health aspects such as the use of drugs, Hoehn &amp; Yahr stages 1-4, and oral health status. The Mini-Mental State Examination, Parkinson's Disease Questionnaire, and Orofacial Myofunctional Evaluation with Scores for Elders were applied. RESULTS: Better oral health status was found in participants diagnosed as Hoehn &amp; Yahr stage 1 compared to the later stages. OMES-Elders scores for appearance/posture, mobility, breathing, and speech functions were different between groups, and decreased overall OMES-Elders was observed across the Hoehn &amp; Yahr stages. A higher number of masticatory cycles was required for chewing and ingestion of the test food in the PD group compared to CG (p < .05). Significant differences were found in the mobility and daily living activities domains and an overall score of QoL between the Hoehn &amp; Yahr stages 1 and 4, and worst orofacial functioning was accompanied by the worst self-perception of QoL in the communication domain (rho = -0.32; p = .034). The use of xerogenic drugs did not affect the OMES-Elders swallowing domain. CONCLUSION: Worse dental condition and performance of orofacial functions was observed in the elders with PD as the disease progresses, and poorer orofacial performance negatively affects their perception of communication skills.
