背景 基于 2018 年分类，我们旨在确定无法获得牙科护理的中国农村人口中牙周炎的患病率、分布和进展情况。方法 1992 年随机纳入 404 名受试者（28.7 +/- 8.9 岁，男：女 = 182：222），并于 1996 年重新纳入。根据新的分类，对分期、级别和程度的患病率和分布进行了表征。将分期进展与临床附着丧失（CAL）和放射学骨丧失（RBL）的进展进行比较。结果 在基线时，94.1%的村民患有牙周炎，其中53.7%处于III/IV期。 III/IV期的患病率从15~24岁年龄组的18.2%增加到25~34岁组的60.9%和35~44岁组的88.7%。男性村民中III/IV期、广泛性和C级牙周炎的发病率显着高于女性村民。 1996年，牙周炎患病率上升至98.5%，其中Ⅲ/IV期为80.0%。此外，根据纵向 Delta CAL，84.2% 的村民患有 C 级牙周炎。进展率（>= 1 个部位 Delta CAL >= 3 mm）为 63.7%。 I/II 期的分期进展与 CAL 和 RBL 进展显着相关，但在 III/IV 期未发现这种关联。在疾病进展为 III/IV 期的受试者中，90.4% 从局部病例转变为全身病例。此外，在III/IV期中观察到天花板效应。结论在无法获得牙科护理的村民中，94.1%患有牙周炎，其中根据2018年的分类，超过一半患有III/IV期疾病。大多数病例表现为牙周进展迅速。尽管 I/II 期的分期进展与 CAL 和 RBL 进展显着相关，但 III/IV 期存在天花板效应。
Background Based on the 2018 classification, we aimed to determine the prevalence, distribution, and progression of periodontitis in the rural Chinese population without access to dental care.Methods In all, 404 subjects (28.7 +/- 8.9 years, M:F = 182:222) were randomly enrolled in 1992 and re-called in 1996. With the new classification, the prevalence and distribution of stage, grade, and extent were characterized. Stage progression was compared with the progression of clinical attachment loss (CAL) and radiographic bone loss (RBL).Results At baseline, 94.1% villagers suffered from periodontitis, of whom 53.7% were in stage III/IV. The prevalence of stage III/IV increased from 18.2% in the age group of 15 to 24 years to 60.9% in 25 to 34-year-old group and 88.7% in the 35 to 44-year-old group. Significantly more stage III/IV, generalized, and grade C periodontitis were found in male villagers than female villagers. In 1996, the prevalence rate of periodontitis increased to 98.5%, with 80.0% in stage III/IV. Further, 84.2% villagers presented with grade C periodontitis based on longitudinal Delta CAL. The rate of progression (>= 1 site with Delta CAL >= 3 mm) was 63.7%. Stage progression correlated significantly with CAL and RBL progression in stage I/II, but this association was not found in stage III/IV. Among subjects with disease progression in stage III/IV, 90.4% shifted from localized to generalized cases. Furthermore, ceiling effects were observed in stage III/IV.Conclusions In villagers without access to dental care, 94.1% suffered from periodontitis, with more than half having stage III/IV disease based on the 2018 classification. The majority cases presented with rapid periodontal progression. Although stage progression correlated significantly with CAL and RBL progression in stage I/II, ceiling effects existed in stage III/IV.
