AimTo propose a framework for consistently applying the 2018 periodontal status classification scheme to epidemiological surveys (Application of the 2018 periodontal status Classification to Epidemiological Survey data, ACES).Proposed FrameworkWe specified data requirements and workflows for either completed or planned epidemiological surveys, utilizing commonly collected measures of periodontal status (clinical attachment levels [CAL], probing depths, bleeding on probing), as well as additional necessary variables for the implementation of the 2018 periodontal status classification (tooth loss due to periodontitis and complexity factors). Following detailed instructions and flowcharts, survey participants are classified as having periodontal health, gingivitis or periodontitis. Rates of edentulism must also be reported. In cases of periodontitis, instructions on how to compute the stage and extent are provided. Assessment of grade can be derived from CAL measurements (or from radiographic alveolar bone loss data) in relation to root length and the participant's age.ConclusionsACES is a framework to be used in epidemiological studies of periodontal status that (i) have been completed, and in which stage and grade according to the 2018 classification are inferred retroactively, or (ii) are being planned. Consistent use of the proposed comprehensive approach will facilitate the comparability of periodontitis prevalence estimates across studies.

ACES：2018年牙周状况分类方案应用于流行病学调查数据的新框架

目的提出一个框架，将 2018 年牙周状况分类方案一致应用于流行病学调查（Application of the 2018 periodontal status Classification to Epidemiological Survey data，ACES）。拟议框架我们利用共同收集的数据，指定了已完成或计划的流行病学调查的数据要求和工作流程牙周状态的测量（临床附着水平 [CAL]、探诊深度、探诊出血），以及实施 2018 年牙周状态分类的其他必要变量（牙周炎和复杂因素导致的牙齿脱落）。根据详细的说明和流程图，调查参与者被分为牙周健康、牙龈炎或牙周炎。还必须报告缺齿率。对于牙周炎，提供了如何计算阶段和程度的说明。等级评估可以根据与牙根长度和参与者年龄相关的 CAL 测量（或放射学牙槽骨丢失数据）得出。结论 ACES 是一个用于牙周状况流行病学研究的框架，(i) 已经完成，并且根据 2018 年分类追溯推断哪个阶段和等级，或 (ii) 正在计划中。一致使用所提出的综合方法将有助于跨研究的牙周炎患病率估计的可比性。
