Abstract

Purpose

The objective was to determine the responsiveness properties of the Oral Health Impact Profile (OHIP) short-forms and 36-item Short-Form (SF-36) in complete denture treatment, and further to evaluate the association between patients’ satisfaction and improvements in oral and general health-related quality of life (OHRQoL and HRQoL) after fitting of new, complete dentures.

Methods

Study data were obtained from the ‘Dentures for the Elders through Public Funding’ study conducted in Kaohsiung County. A total of 224 subjects received denture treatments with 6-month follow-up and pre-/post-treatment interviews by questionnaire. The OHIP and SF-36 were used to measure OHRQoL and HRQoL. In addition, specific questions investigating seven aspects of patients’ satisfaction were used to measure the patients’ perceptions of complete denture success. The responsiveness of all outcome measures and their dimensions were assessed by effect size (ES). Multivariable analysis was used to examine the association between patients’ satisfaction and OHIP/SF-36 while adjusting for demographic characteristics.

Results

There were improvements with regard to the ‘physical pain’ (ES = 0.19) and ‘psychological discomfort’ (ES = 0.42) dimensions of the Taiwanese short-form OHIP (OHIP-14T) after new complete denture treatment, but only improvement in the ‘general health’ (ES = 0.17) dimension in the SF-36 measure. Patients satisfied with ‘comfort’ and ‘ease of cleaning’ of their new dentures were significantly associated with the improvement of the OHIP-49 and OHIP-14T.

Conclusions

This study suggests that denture treatments are associated with improvements of OHRQoL, but not in HRQoL. Furthermore, patients’ satisfaction was significantly associated with responsiveness of OHRQoL but less significantly associated with responsiveness of HRQoL.
