A Retrospective Study on Usage of Removable Partial Dentures by Patients in Comprehensive Dental Clinic
This study aimed to investigate used rate of removable partial denture (RPDs) in a comprehensive dental clinic, associated factors and use or nonuse reasons. Using archived files from the comprehensive dental clinic at the Faculty of Dentistry, Chiang Mai University, a list of 243 maintenance patients treated with 358 RPDs was created. Examiners telephoned all of the listed patients and interviewed 189 patients regarding the use of 282 RPDs. Of 189 patients, 151 (79.7%) were still using the original 232 RPDs (82.3%). Between RPDs use and nonuse group, there were significant differences in mean age, medical history, denture history, Eichner’s classification, denture present in one or two arches and denture satisfaction. The main reason for RPDs user was chewing (76.8%). For nonuser, the main reason was discomfort. Moreover, the RPDs user and nonuser groups did not show significant differences in average chewing function score at p=0.640.
