广东省12～15岁人群恒牙龋病抽样调查报告(2015-2016年)

A sampling survey of permanent teeth caries in 12-15-year-old population in Guangdong Province(2015-2016)

目的了解广东省12~15岁人群恒牙龋病状况,为广东省口腔卫生保健工作提供信息支持。方法采用多阶段分层等容量随机抽样的方法,抽取广东省12、13、14、15岁城乡常住人口各1 920人,男女各半,城乡各半。按照第四次全国口腔健康流行病学调查方案的牙列检查方法和标准,使用CPI探针检查全口恒牙冠龋患病情况。计算患龋率、龋均、充填率等。结果 12、13、14、15岁人群患龋率分别为43.07%、45.31%、49.69%、52.86%,龋均分别为1.06、1.13、1.38、1.59,龋齿充填率分别为20.19%、21.50%、22.86%、21.33%。患龋率和龋均两项指标均随着年龄增加而增加,差异有统计学意义(P<0.000 1);患龋率和龋均两指标城乡之间比较,农村高于城市,差异有统计学意义(P<0.001);不同性别间比较,女性高于男性,差异有统计学意义(P<0.000 1)。与2005年相比,12岁人群患龋率和龋均均升高。结论广东省12~15岁人群患龋率和龋均随着年龄增加而增加,农村高于城市,女性高于男性,充填率低。

Objective To explore the caries status of permanent teeth among 12-15-year-old population in Guangdong Province, and to provide information support for oral health care. Methods A cross-sectional survey was carried out among 7 680 urban and rural residents in Guangdong Province. Subjects were from four different age groups（aged12, 13, 14 and 15）, with 1 920 people in each group. An equal-sized stratified multistage randomly sampling was used,with a gender ratio of half to half in each group. According to the criteria of clinical dentition examination of the fourth national oral health survey, the crown caries of permanent teeth in the whole mouth were recorded using CPI probe. And then the prevalence, the mean DMFT（decayed-missing-filled tooth）, the filled rate were calculated. Results The prevalence of crown caries in the groups of aged 12, aged 13, aged 14, aged 15 were 43.07%, 45.31%, 49.69%, 52.86%, respectively. The mean DMFTs were 1.06, 1.13, 1.38, 1.59, respectively. The filled rates were 20.19%, 21.50%, 22.86%,21.33%, respectively. The prevalence and the mean DMFT increased with age（P 0.001）, and both were higher than that in 2005. There were significant differences in the prevalence and the mean DMFT between urban and rural areas and between male and female（P 0.001）. Conclusion According to the criteria of the mean DMFT in 12-year-old population of WHO, the severity of caries of permanent teeth in Guangdong was regarded as ＂very low＂. But the severity was higher than that in 2005, and the filled rate was low.
