Periodontitis is associated with oral health‐related quality of life in individuals with end‐stage renal disease

Abstract

Abstract Aim The aim of the present study was to evaluate whether periodontitis is independently associated with oral health‐related quality of life (OHRQoL) in individuals with end‐stage renal disease (ESRD). Materials and Methods Calibrated examiners assessed 180 adults with ESRD. A full‐mouth periodontal examination was performed at six sites on each tooth. Periodontitis was considered a categorical variable (absent, mild/moderate or severe). OHRQoL was assessed using the simplified version of the Oral Health Impact Profile (OHIP 14 ) questionnaire. Adjusted multivariate Poisson regression analysis was used with a conceptual hierarchical approach to calculate the rate ratio (RR) of OHIP 14 scores for periodontitis according to the severity categories. Results In the adjusted model, mild/moderate and severe periodontitis were significantly associated with poorer OHRQoL compared to the absence of periodontitis [RR = 1.49 (95% confidence interval: 1.16–1.91) and RR 1.77 (95% CI: 1.36–2.30), respectively]. The adjusted domain‐specific analysis revealed that mild/moderate periodontitis significantly impacted the psychological disability domain and severe periodontitis significantly impacted the physical pain, psychological discomfort, physical disability and psychological disability domains. Conclusions Periodontitis exerts an influence on OHRQoL in individuals with ESRD, with a more severe condition impacting different domains.
