AimThe occurrence of periodontal diseases is still to be determined in large samples of major Brazilian cities. This study aimed to assess the periodontal status of adults from Curitiba, Paraná, Brazil, using periodontitis definitions by the Centers for Disease Control and Prevention and the American Academy of Periodontology (CDC/AAP) and the recently published ACES 2018 Classification Framework.Materials and MethodsA multi‐stage probability sampling technique was applied to draw individuals aged 18 or older. A total of 566 individuals underwent a full‐mouth periodontal examination. Periodontitis cases were defined according to the CDC/AAP and the ACES 2018 Classification Framework. Non‐periodontitis cases were classified as healthy or gingivitis. The agreement between the two definitions was calculated.ResultsPeriodontal health was present in 33.6% and 13.8% of individuals, and gingivitis was found in 11.7% and 7.5%, according to CDC/AAP and ACES, respectively. Mild, moderate and severe periodontitis (CDC/AAP) were present in 2.1%, 33.4% and 19.1% of individuals, respectively. Using ACES, 34.3% had Stages I/II and 43.3% had Stages III/IV. The occurrence of periodontitis was higher when a subgroup of individuals aged 30+ were analysed, ranging from 69.6% (CDC/AAP) to 90.1% (ACES). CDC/AAP and ACES agreement for health, gingivitis and periodontitis accounted for 68.8% of the observations.ConclusionsPeriodontal diseases affect more than 66% of the population aged 18+ years. Classic definition by the CDC/AAP and the recently published ACES Framework yielded moderate agreement.

根据 ACES 2018 分类框架和 CDC/AAP 定义发生的牙周病：巴西主要城市的横断面研究


Aim 牙周病的发生仍有待巴西主要城市的大样本确定。本研究旨在使用疾病控制和预防中心和美国牙周病学会 （CDC/AAP） 的牙周炎定义以及最近发布的 ACES 2018 分类框架来评估巴西巴拉那州库里蒂巴成人的牙周状况。共有 566 人接受了全口牙周检查。牙周炎病例根据 CDC/AAP 和 ACES 2018 分类框架进行定义。非牙周炎病例分为健康或牙龈炎。计算两个定义之间的一致性。结果根据 CDC/AAP 和 ACES 的数据，33.6% 和 13.8% 的个体存在牙周健康，11.7% 和 7.5% 的个体存在牙龈炎。轻度、中度和重度牙周炎 （CDC/AAP） 分别见于 2.1% 、 33.4% 和 19.1% 的个体。使用 ACES，34.3% 为 I/II 期，43.3% 为 III/IV 期。当分析 30+ 岁个体的亚组时，牙周炎的发生率更高，范围从 69.6% （CDC/AAP） 到 90.1% （ACES）。CDC/AAP 和 ACES 对健康、牙龈炎和牙周炎的协议占观察结果的 68.8%。结论牙周病影响了超过 66% 的 18+ 岁人口。CDC/AAP 的经典定义和最近发布的 ACES 框架产生了中等一致性。
