To describe the distribution of clinical attachment loss (CAL) and to study risk indicators for chronic periodontitis in a large population-based sample of adolescents and young adults from south Brazil.
This cross-sectional study used a subset of data from a larger survey representative of Porto Alegre, Brazil. The sample consisted of 612 individuals (291 males/321 females) aged 14-29 years. Full-mouth, six sites per tooth clinical examinations were performed by calibrated periodontists. Chronic periodontitis was defined as CAL 3mm affecting two or more teeth. Aggressive periodontitis cases were excluded from the analysis.
CAL 3 and 5mm affected 50.4% and 17.4% of subjects and 9.7% and 1.1% of teeth, respectively. Prevalence of chronic periodontitis ranged between 18.2% and 72.0% among subjects 14-19 and 24-29 years old, respectively. In the multivariable logistic regression analysis, older age [odds ratio (OR)=2.6, 95% confidence interval (CI)=1.7-3.9 and OR=7.2, 95% CI=3.7-14.0 for 20-24 and 25-29 years old, respectively], low socioeconomic status (OR=1.9, 95% CI=1.4-2.7), heavy smoking (OR=1.7, 95% CI=1.1-2.7) and larger amounts of calculus (OR=2.0, 95% CI=1.2-3.2) were significantly associated with chronic periodontitis.
This population of adolescents and young adults had a high prevalence of chronic periodontitis, and its presence was associated with age, socioeconomic status, smoking and calculus.
描述临床附着丧失（CAL）的分布，并研究来自巴西南部的大型基于人群的青少年和年轻成年人样本中慢性牙周炎的风险指标。
本横断面研究使用了巴西阿雷格里港更大规模调查的一个子集数据。该样本由 612 名年龄在 14-29 岁的个体（291 名男性/321 名女性）组成。由经过校准的牙周病医生对每颗牙齿的六个部位进行全口临床检查。将 CAL 为 3mm，影响两颗或更多牙齿的慢性牙周炎定义为 CAL 3mm。排除侵袭性牙周炎病例进行分析。
CAL 3mm 和 5mm 影响了 50.4%和 17.4%的受试者以及 9.7%和 1.1%的牙齿。14-19 岁和 24-29 岁的受试者中慢性牙周炎的患病率分别在 18.2%-72.0%之间。在多变量逻辑回归分析中，年龄较大[比值比（OR）=2.6，95%置信区间（CI）=1.7-3.9 和 OR=7.2，95%CI=3.7-14.0，分别为 20-24 岁和 25-29 岁]、社会经济地位较低（OR=1.9，95%CI=1.4-2.7）、大量吸烟（OR=1.7，95%CI=1.1-2.7）和牙石较多（OR=2.0，95%CI=1.2-3.2）与慢性牙周炎显著相关。
该青少年和年轻成年人人群的慢性牙周炎患病率较高，其存在与年龄、社会经济地位、吸烟和牙石有关。
