Parkinson’s Disease (PD) is the second most common neurodegenerative disease after Alzheimer's disease. It is one of the movement disorders that can affect oro-facial conditions. It is more common in the elderly, having an average age of onset of around 60 years.
The aim was to study orofacial functions in patients suffering from PD with partial or total edentulism, wearing removable prostheses.
Forty-eight (48) elders, rehabilitated with removable dentures, were included: 24 patients suffering from Parkinson's disease constitute the Study Group (SG), and 24 subjects not suffering from Parkinson's disease or neurological degenerative diseases represent the Control Group (CG).
In SG, the severity of Parkinson's disease was assessed according to the Unified Parkinson's Disease Rating objective motor scale III, and oro-facial dysfunctions were evaluated using Nordic Orofacial Test-Screening (NOT-S). The duration of the use of dental prostheses expressed in years has been reported. In both the groups, the subjective chewing index for the analysis of masticatory ability and the two-color chewing gum test for the analysis of masticatory efficiency were conducted .
There was a statistically significant difference between the SG and CG compared to the NOT-S (P = 0.001).
Analyzing the study group, a statistically significant correlation was found between the masticatory efficiency and prosthetic years of use (rs = 0.436; P <0.05); instead, no statistically significant correlation was found between the masticatory efficiency and the severity of Parkinson's disease.
In our study, we did not find differences between SG and CG in terms of the degree of masticatory efficiency; therefore, only a correlation between the duration of use of dental prostheses and the degree of masticatory efficiency was found.
