Classification of the periodontal conditions is indispensable for epidemiological data in order to guide situational awareness and therapeutic strategies. The new classification of periodontal diseases and conditions introduced by the American Academy of Periodontology and the European Federation of Periodontology (AAP/EFP), however, has not yet been applied to population-based studies. The aim of the present study was to compare the prevalence of periodontitis between the AAP/EFP and the CDC/AAP classification system and to evaluate the accuracy of the new AAP/EFP classification system against the CDC/AAP case definition for population-based studies.

2017 年 AAP/EFP 病例定义与 CDC/AAP 定义在基于人群的研究中的表现

牙周病的分类对于流行病学数据是必不可少的，以指导态势感知和治疗策略。然而，美国牙周病学会和欧洲牙周病学联合会 (AAP/EFP) 引入的牙周病和病症新分类尚未应用于基于人群的研究。本研究的目的是比较 AAP/EFP 和 CDC/AAP 分类系统之间的牙周炎患病率，并评估新的 AAP/EFP 分类系统与 CDC/AAP 病例定义在人群研究中的准确性.
