Summary The present study examined the association of denture quality and health‐related quality of life (HRQoL) in patients with removable dentures. In a study of 171 consecutive patients with removable partial dentures or complete dentures (mean age: 68·0 ± 9·3 years) at a university‐based prosthodontic clinic, dentists rated two aspects of denture quality (stability and aesthetics) using a 100‐mm visual analog scale (VAS). HRQoL was evaluated using the mental and physical component summary (MCS and PCS) scores of the Medical Outcomes Study Short‐Form 36‐Item Health Survey (SF‐36). Oral health‐related quality of life (OHRQoL) was evaluated using the Oral Health Impact Profile‐Japanese version (OHIP‐J). The associations among denture quality, OHRQoL, and HRQoL were examined by linear regression models. Bivariable linear regression analyses revealed that denture stability was significantly associated with the SF‐36 MCS [regression coefficient = 0·52 for a 10‐unit increase in denture stability on a 0–100 VAS, 95% confidence interval (CI): 0·03–1·00, P = 0·04], but not with the PCS (0·11, 95% CI: −0·49 to 0·70). Denture aesthetics was not related to the PCS or the MCS (0·22, 95% CI: −0·44 to 0·88 or 0·07, 95%CI: −0·47 to 0·62). When OHIP‐J was added to the regression model, this variable was substantially and significantly associated with the MCS and PCS summary scores; in addition, the regression coefficient for denture quality decreased in magnitude and was statistically nonsignificant in all analyses. The quality of removable dentures had a minimal effect on HRQoL in patients with removable dentures, and this association was mediated by OHRQoL.
