Abstract
OBJECTIVE: To evaluate masticatory function in individuals with Parkinson's disease (PD) during levodopa "on" period using new removable dental prosthesis. MATERIALS AND METHODS: A total of 34 elderly individuals with PD (n = 17, mean age = 69.41 ± 4.65 years) or without PD (n = 17, mean age = 70.71 ± 4.65 years) were recruited for this study. Participants received new complete dentures and/or removable partial dentures. Two months after the subjects were free of any prostheses discomfort, masticatory function was assessed. A kinesiographic device was used to measure the range of jaw motion and jaw movements while chewing a silicone test material (Optocal). Masticatory performance was determined by median particle size (X50) of the Optocal after 40 masticatory cycles. Maximum bite force was assessed by a strain sensor placed in the bilateral first molars region. Data were analyzed by t test (P < 0.05). RESULTS: The PD group showed a decreased range of jaw motion, longer duration and slower velocity of the masticatory cycle (P < 0.05), higher X50 value, and lower maximum bite force (P < 0.05). CONCLUSION: PD patients have impaired masticatory function during levodopa "on" periods compared to controls. CLINICAL RELEVANCE: Knowledge that PD is associated with impaired masticatory function is important to dental professionals in decision making related to prosthetics and general dental treatment.
