 This study examines the differences in orofacial function between individuals with Parkinson's disease, PD, and those without PD. The results show that individuals with PD experience significant impairments in their orofacial function, including difficulty chewing and swallowing, as well as increased drooling and xerostomia. Additionally, individuals with PD report higher levels of orofacial pain than those without PD. These findings suggest that individuals with PD may benefit from targeted interventions to improve their orofacial function.
