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 periodontal examinations at six sites per tooth 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 version 14 (OHIP‐14), were recorded at the follow‐up examination. Mean ratios (MRs) and 95% confidence intervals (95% CIs) were estimated adjusting for age, sex, smoking, systemic diseases, tooth loss, and baseline periodontitis diagnosis. Results Five‐hundred and ninety‐nine individuals were analysed. 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.
