Abstract
AIM: To determine the association between periodontitis Stage and Grade with oral health related quality of life (OHRQOL). MATERIALS AND METHODS: This cohort was derived from the Porto Alegre Study. The original sample was representative of more than 3 million inhabitants of a Brazilian urban area. Full-mouth 6-sites per tooth periodontal examinations were performed at baseline and 5 years later. Periodontitis grade was determined by direct evidence of progression of attachment loss over the follow-up. Stage of periodontitis and OHRQOL, determined by the Oral Health Impact Profile (OHIP-14), were recorded at the follow-up examination. Mean rations (MR) and 95% confidence intervals (95%CI) were estimated adjusting for age, sex, smoking, systemic diseases, tooth loss and baseline periodontitis diagnosis. RESULTS: 599 individuals were analyzed. Individuals with periodontitis Grade C + Stage II (MR=1.49; 95%CI=1.08-2.04) and Stages III/IV (MR=1.83; 95%CI=1.25-2.66) had significantly higher OHIP scores than those without periodontitis or with periodontitis Stage I/Grade B. Individuals with periodontitis Stages II and III/IV + Grade B did not differ from those without periodontitis or with periodontitis Stage I/Grade B. CONCLUSION: Severity and progression rate of periodontitis are associated with poor OHRQOL. This article is protected by copyright. All rights reserved.
