AimTo assess the prevalence of severe periodontitis based on the population‐based CONSTANCES cohort using a validated self‐reported questionnaire.Materials and MethodsIndividuals were selected from the adult population in France using a random sampling scheme. Analyses were restricted to those invited in 2013–2014 who completed the periodontal health questionnaire at the 2017 follow‐up. The risk of severe periodontitis was assessed using the periodontal screening score (PESS) and weighting coefficients were applied to provide representative results in the general French population.ResultsThe study included 19,859 participants (9204 men, mean age: 52.8 ± 12.6 years). Based on a PESS ≥ 5, 7106 participants were at risk of severe periodontitis, corresponding to a weighted prevalence of 31.6% (95% confidence interval: 30.6%–32.7%). This prevalence was higher among participants aged 55 and over, those with lower socio‐economic status as well as current smokers, e‐cigarette users and heavy drinkers. Among individuals at risk of severe periodontitis, only 18.8% (17.3%–20.4%) thought they had gum disease, although 50.5% (48.6%–52.5%) reported that their last dental visit was less than 6 months.ConclusionsThe present survey indicates that (1) self‐reported severe periodontitis is highly prevalent with marked disparities between groups in the general French adult population, and (2) periodontitis could frequently be under‐diagnosed given the low awareness.

自我报告的严重牙周炎的患病率：来自基于人群的 CONSTANCES 队列的数据

目的使用经过验证的自我报告问卷，基于基于人群的 CONSTANCES 队列来评估严重牙周炎的患病率。材料和方法使用随机抽样方案从法国成年人群中选择个体。分析仅限于 2013 年至 2014 年受邀且在 2017 年随访时完成牙周健康问卷的人员。使用牙周筛查评分（PESS）评估严重牙周炎的风险，并应用加权系数来提供法国普通人群的代表性结果。结果该研究包括 19,859 名参与者（9204 名男性，平均年龄：52.8 ± 12.6 岁）。根据 PESS ≥ 5，7106 名参与者面临严重牙周炎的风险，对应的加权患病率为 31.6%（95% 置信区间：30.6%–32.7%）。在 55 岁及以上的参与者、社会经济地位较低的参与者以及当前吸烟者、电子烟使用者和酗酒者中，这种患病率较高。在有严重牙周炎风险的个体中，只有 18.8% (17.3%–20.4%) 认为自己患有牙龈疾病，尽管 50.5% (48.6%–52.5%) 报告说他们最后一次看牙医的时间少于 6 个月。 结论 本调查表明(1) 在法国普通成年人口中，自我报告的严重牙周炎非常普遍，各群体之间存在显着差异；(2) 由于认识程度较低，牙周炎经常被漏诊。
