The aim of this cross-sectional study was to investigate the oral health status of Hani 12-year-old children in Yunnan, a province in Southwest China.
This study employed a multistage sampling method to recruit children from local primary schools. Two calibrated dentists examined the status of dental caries, gingival bleeding and dental fluorosis by adopting the diagnosis criteria recommended by the World Health Organization. A self-administrated questionnaire was distributed. The chi-square test and multivariate logistic regression were conducted.
This study invited 480 Hani children, and recruited 413 children (52% boys) (response rate: 86%). The dental caries prevalence was 52%, and the caries experience associated with the mean (standard deviation) decayed, missing and filled teeth (DMFT) score was 1.10 (1.46). Gingival bleeding was diagnosed in 252 children (61%), and dental fluorosis was found in two children (0.5%). The results of the regression model indicated the prevalence of dental caries were associated with sugary snacking habits ( = 0.002). The prevalence of gingival bleeding was related to the mother's education level as well as the child's monthly pocket money ( < 0.05).
Dental caries and gingival bleeding were prevalent among 12-year-old Hani children in the Yunnan province in China. Dental fluorosis was uncommon.
本横断面研究旨在调查中国西南云南省哈尼族 12 岁儿童的口腔健康状况。
本研究采用多阶段抽样方法，从当地小学招募儿童。由两名经过校准的牙医采用世界卫生组织推荐的诊断标准，检查龋齿、牙龈出血和氟斑牙的状况。发放了一份自填式问卷。采用卡方检验和多变量逻辑回归进行分析。
本研究邀请了 480 名哈尼族儿童，招募了 413 名儿童（52%为男孩）（应答率：86%）。龋齿患病率为 52%，与平均（标准差）龋齿、缺失和补牙（DMFT）评分相关的龋齿患病经历为 1.10（1.46）。252 名儿童（61%）被诊断为牙龈出血，两名儿童（0.5%）患有氟斑牙。回归模型的结果表明，龋齿的患病率与含糖零食的饮食习惯有关（ = 0.002）。牙龈出血的患病率与母亲的教育水平以及儿童的月零花钱有关（<0.05）。
在中国云南省，12 岁哈尼族儿童中龋齿和牙龈出血较为普遍，氟斑牙少见。
