There are limited data about the epidemiology and risk factors for aggressive periodontitis (AgP) in Latin American and Brazilian populations. The aim of this study was to assess the prevalence of AgP and the risk associated with demographic variables, smoking behavior, and other periodontal variables in a young urban population in southern Brazil.
A representative sample of 612 subjects aged 14 to 29 years were sampled using a multistage probability method. A full-mouth clinical examination of six sites per tooth and an interview were performed in a mobile examination center. Subjects in the age groups 14 to 19 years and 20 to 29 years were classified with AgP if they had four or more teeth with attachment loss > or =4 mm or > or =5 mm, respectively.
AgP was found in 5.5% of the subjects. The disease occurred equally among males and females, but was twice as prevalent among non-whites than whites. In the age groups 20 to 24 years and 25 to 29 years, the AgP subjects had a significantly higher prevalence of tooth loss (90.2% versus 40.4% and 86.1% versus 43.4%, P <0.01) and mean number of missing teeth (2.6 versus 0.9 and 3.4 versus 1.5, P <0.05) than subjects without attachment loss. The AgP subjects also had significantly higher percentages of sites with dental plaque (P <0.0001), gingival bleeding (P <0.05), and supragingival calculus (P <0.0001) than normal subjects. The risk for AgP was higher in the 25- to 29-year than the 14- to 19-year age groups (odds ratio [OR] = 6.2), in the low than middle or high socioeconomic status (OR = 4.5), in moderate or heavy smokers than nonsmokers (OR = 3.1), and in subjects with > or =10% versus <10% sites with supragingival calculus (OR = 3.6).
Socioeconomic status, smoking, and dental calculus were significant risk indicators of aggressive periodontitis in this population. Suitable periodontal prevention programs implementing these risk indicators may prevent or reduce the prevalence of aggressive periodontitis in this and similar populations.
关于拉丁美洲和巴西人群侵袭性牙周炎（AgP）的流行病学和危险因素的数据有限。本研究的目的是评估巴西南部年轻城市人群中AgP的患病率以及与人口统计学变量、吸烟行为和其他牙周变量相关的风险。
采用多阶段概率抽样方法，对612名年龄在14至29岁的受试者进行代表性抽样。在移动检查中心对每颗牙齿的六个部位进行全口临床检查并进行访谈。14至19岁和20至29岁年龄组的受试者，如果分别有四颗或更多颗牙齿的附着丧失≥4mm或≥5mm，则被归类为患有AgP。
5.5%的受试者患有AgP。该疾病在男性和女性中发病率相同，但在非白人中的患病率是白人的两倍。在20至24岁和25至29岁年龄组中，患有AgP的受试者牙齿缺失的患病率（分别为90.2%对40.4%和86.1%对43.4%，P<0.01）和平均缺失牙数（分别为2.6对0.9和3.4对1.5，P<0.05）显著高于无附着丧失的受试者。与正常受试者相比，患有AgP的受试者牙菌斑部位（P<0.0001）、牙龈出血（P<0.05）和龈上牙石（P<0.0001）的百分比也显著更高。25至29岁年龄组患AgP的风险高于14至19岁年龄组（优势比[OR]=6.2），低社会经济地位者高于中或高社会经济地位者（OR=4.5），中度或重度吸烟者高于非吸烟者（OR=3.1），龈上牙石部位≥10%的受试者高于<10%的受试者（OR=3.6）。
社会经济地位、吸烟和牙石是该人群侵袭性牙周炎的重要风险指标。实施这些风险指标的适当牙周预防计划可能预防或降低该人群及类似人群中侵袭性牙周炎的患病率。
