To determine the association between periodontitis stage and grade with oral-health-related quality of life (OHRQoL).
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.
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.
Severity and progression rate of periodontitis are associated with poor OHRQoL.
确定牙周炎的严重程度和分级与口腔健康相关生活质量（OHRQoL）之间的关系。
本队列来自于阿雷格里港研究。原始样本代表了巴西一个城市地区超过 300 万居民。在基线和 5 年后，对每个牙齿的六个位点进行全口牙周检查。通过随访期间附着丧失的直接证据来确定牙周炎的分级。牙周炎的阶段和 OHRQoL 通过口腔健康影响概况 14 版（OHIP-14）确定，并在随访检查时记录。调整年龄、性别、吸烟、系统性疾病、牙齿缺失和基线牙周炎诊断后，估计平均比值（MR）和 95%置信区间（95%CI）。
对 599 名个体进行了分析。患有牙周炎分级 C+阶段 II（MR=1.49；95%CI=1.08-2.04）和 III/IV 期（MR=1.83；95%CI=1.25-2.66）的个体的 OHIP 评分明显高于无牙周炎或牙周炎 I/分级 B 的个体。患有牙周炎 II 期和 III/IV 期+分级 B 的个体与无牙周炎或牙周炎 I/分级 B 的个体没有差异。
牙周炎的严重程度和进展速度与较差的 OHRQoL 相关。
