To assess the prevalence of gingival bleeding, calculus and periodontal pockets among 18-year-old males. In addition, to verify whether these conditions are associated with years of education and family income.
A cross sectional survey was carried out. A representative sample of 18-year-old males living in Florianópolis, Brazil, was selected from the Brazilian Army applicant list. Clinical and socioeconomic data were collected through dental examinations and interviews, respectively. Socioeconomic data included the subjects and their parents' years of education, and family income. A single dentist carried out the dental examinations looking for gingival bleedings after probing, calculus and shallow and deep periodontal pockets (3.5 mm to 5.5 mm and 5.5 mm and over). The associations between periodontal conditions and socioeconomic variables were analyzed using the qui-square test.
A total of 286 people participated in the study. Intra-examiner agreement was high. All kappa values were above 0.7. The prevalence of gingival bleeding, calculus, shallow and deep periodontal pockets were 86%, 50.7%, 7.7% and 0.3% respectively. There were associations between gingival bleeding and all socioeconomic variables (p<0.001). Calculus were associated with the subject's and their father's low educational level (p<0.05) and with their mother's low educational level (p<0.01). Periodontal pockets were associated with their father's low educational level (p<0.05).
The prevalence of periodontal pockets was very low, while gingival bleeding and calculus were high. General periodontal health of the studied population was good.
评估18岁男性牙龈出血、牙石和牙周袋的患病率。此外，验证这些情况是否与受教育年限和家庭收入有关。
进行了一项横断面调查。从巴西陆军申请人名单中选取了居住在巴西弗洛里亚诺波利斯的18岁男性的代表性样本。临床和社会经济数据分别通过牙科检查和访谈收集。社会经济数据包括受试者及其父母的受教育年限和家庭收入。由一名牙医进行牙科检查，探查后寻找牙龈出血、牙石以及浅、深牙周袋（3.5毫米至5.5毫米以及5.5毫米及以上）。使用卡方检验分析牙周状况与社会经济变量之间的关联。
共有286人参与了该研究。检查者内部一致性较高。所有kappa值均高于0.7。牙龈出血、牙石、浅牙周袋和深牙周袋的患病率分别为86%、50.7%、7.7%和0.3%。牙龈出血与所有社会经济变量之间均存在关联（p<0.001）。牙石与受试者及其父亲的低教育水平相关（p<0.05），与母亲的低教育水平相关（p<0.01）。牙周袋与父亲的低教育水平相关（p<0.05）。
牙周袋的患病率非常低，而牙龈出血和牙石的患病率较高。所研究人群的总体牙周健康状况良好。
