ANALYSIS OF THE STOMATOGNATHIC SYSTEM FUNCTIONS IN AGED DENTURE WEARERS

Abstract

Objective: To evaluate the stomatognathic system functions in aged denture wearers. Material and Methods: A phonoaudiological assessment was carried out consisting of anamnesis and a two-step clinical examination. Firstly, general facial and body features were observed. Secondly, orofacial structures and oral functions were checked through observation and palpation. The sample was composed of individuals aged more than 60 years, wearing upper or lower partial/complete dentures. Results: A total of 44 elderlies were examined, who were divided into three groups according to the type of denture: group 1 including elderlies with no dental issues (n=18); group 2 consisting of elderlies wearing upper and lower complete dentures (n=14); and group 3 including elderlies with upper and lower partial dentures (n=12). Of these, 84.9% were female. Modifications of the swallowing function were observed in 55.5% of the subjects in group 1, 85.7% in group 2, and 91.6% in group 3, hence showing that denture wearers had higher prevalence of alterations in this function as compared to those in the control group. As to the chewing function, we found changes in 57.1% of subjects in group 2, and 66.6% in groups 1 and 3. Conclusion: The use of dentures leads to modifications in the functions of the stomatognathic system concerning chewing and swallowing. Furthermore, the type of denture used by the individual may cause different changes with respect to the structures. DESCRIPTORS Speech. Language and Hearing Sciences. Dental Prosthesis. Mastication.
