Abstract
BackgroudThe objectives of this study were to try to identify the key dimension in satisfaction from the combination of satisfaction clusters, and its effect on the change of OHRQoL(Oral Health-related Quality of Life) of elderly denture users.MethodsThis follow-up study was conducted in subjects aged 65 years and over. All participants (n = 2128) completed questionnaires before and approximately 6 months after receiving complete denture. Information obtained by questionnaire included demographic characteristics, patients’ self-satisfaction rate and OHRQoL. The 6 satisfaction dimensions (including speaking, stability, esthetic, chewing, doctor and general dimensions) were classified as 5 cluster groups, which is the group of not at all satisfied in all dimensions (NAS); only satisfied with doctor and general dimensions(SDG); moderate satisfaction group(MS); quite satisfied group(QS); the highly satisfied group(HS) by an analysis of PCA (Principle component analysis) and CA (cluster analysis). Multiple linear regression was adapted to estimate the association between satisfaction and the responsiveness of OHIP-7T (Oral Health Impact Profile).ResultsWhen compared to the cluster “NAS”, 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 “MS” (β = 4.33(2.92–5.74)) and group “SDG” (β = 3.25(2.10–4.41)). An increasing trend was detected in patient-rating satisfaction and OHRQoL. The satisfaction cluster group is an important factor of OHRQoL after adjusting for other confounders.ConclusionPsychological-related aspects is the greatest impacting dimension on OHRQoL among denture wearers in Taiwan elderly. Better communication from the dental professional team with denture patients would improve their OHRQoL.
Highlights
Patient-report outcome (PROs) provide practice guides for clinical treatment
Multiple linear regression analysis was adapted to estimate the association between patient satisfaction and the responsiveness of Oral Health Impact Profile the Taiwanese version (OHIP-7T), while adjusting for pretreatment score, gender, age, education level, economic status, and personal habits, the experience of complete denture use before, perceived oral and general health
Our paper is the first study to evaluate the multi-dimension cluster satisfaction patterns related to the Oral health-related quality of life (OHRQoL), which provide a concept to deal with the collinearity of distinct satisfaction dimensions
Summary
Patient-report outcome (PROs) provide practice guides for clinical treatment. Despite declining edentulism and increasing implant treatment, the need for complete denture treatment will remain substantial in the future [1,2,3,4]. For most edentulous patients in Taiwan, complete denture will be the first treatment option [5]. The growing elderly population worldwide and the extended edentulism status have increased the need for successful denture treatment. Denture treatment is a timeconsuming process, the follow-up adjustment of denture fitting and tissue adaptation to get a satisfactory outcome is important. It has been found that psychological factors may play an important role in those patients who experience difficulty in adapting to new dentures [6,7,8]
