The association between denture satisfaction and OHRQoL - a follow-up study

Abstract Backgroud: The objectives were to evaluate the association between edentate patients’ self-ratings satisfaction and OHRQoL and to identify the determinants of denture satisfaction that best predict OHRQoL. Methods: This prospective study was conducted in subjects aged 65 years and over. All subjects completed questionnaires before and approximately 6 months after receiving complete denture. Information obtained by questionnaire included demographic characteristics, patients’ satisfaction and OHRQoL. The six satisfaction dimensions were classified as five cluster groups by an analysis of PCA and CA. Multiple linear regression was adapted to estimate the association between satisfaction and the responsiveness of OHIP7T. Results: The satisfaction cluster group is an important factor of OHRQoL after adjusting for other confounders. When compared to the cluster “HDS”, the greatest improvement of OHRQoL after treatment was found in the group “HS” (β=7.31(6.26-8.36), followed by group “QS” (β=4.71(3.54-5.87)), group “AS”(β=4.33(2.92-5.74)) and group “SDG” (β=3.25(2.10-4.41)). A statistically significant trend was detected in patient-rating satisfaction and OHRQoL. Conclusion: Psychological value is the greatest impacting dimension on OHRQoL among denture wearers in Taiwan elderly.
