Complete dentures and oral health-related quality of life -- do coping styles matter?

Abstract

Oral health-related quality of life (OHRQOL) in edentulous patients with complete dentures is often impaired. This paper investigates the effect of different coping styles on OHRQOL. (a) To assess OHRQOL of edentulous patients with conventional complete dentures, and (b) to investigate if individual differences in these patients' styles of coping with stress affect their OHRQOL. Data were collected from 249 fully edentulous patients with complete dentures (mean age: 66.0 years) who responded to a mailed survey (adjusted response rate: 48.8%). OHRQOL was measured with the 14-item short form of the oral health impact profile (OHIP). Ratings of coping strategies were obtained using the 28-item Brief COPE, an instrument measuring various styles of coping with stress. Linear regression analyses were used to explore the relationships between coping styles, background variables such as age, gender, income, and age of prosthesis, and the patients' OHRQOL. About 35% of the respondents reported impacts from their oral conditions on their overall OHRQOL (OHIP-14 total score) occasionally, fairly often, or often. Physical pain was even more prevalent, with 53.3% of the respondents reporting pain impacts. The linear regression model (P < 0.0001) explained 31.1% of the variation in the OHIP-14 total score. The coping variables instrumental support, behavioral disengagement, substance abuse, denial, and religion were significant negative predictors of OHRQOL. Only emotional support was a significant positive predictor of OHRQOL. Wearing conventional complete dentures has a significant impact on OHRQOL. This impact is moderated by the styles a patient uses to cope with stress. Using emotional support has a positive effect on OHRQOL, while other coping styles, namely instrumental support, behavioral disengagement, substance abuse, denial, and religion are significant negative predictors of OHRQOL.
