广东省12岁人群氟牙症抽样调查报告(2015—2016年)

Dental fluorosis of permanent teeth among 12-year-old people of Guangdong Province: a sample investigation (2015—2016)

目的了解广东省12岁人群恒牙患氟牙症状况,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岁城乡常住人口1 920人,男女各半。按照第四次全国口腔健康流行病学调查方案中临床氟牙症的检查方法和标准,检查全口恒牙牙冠氟牙症情况。数据采用SAS9.2软件统计,计算出患病率和氟牙症指数,比较性别间,城乡间差别;并与2005年、1995年广东省12岁人群患氟牙症情况比较。结果 2015—2016年12岁组人群氟牙症患病率为5.05%,氟牙症指数为0.108,性别间差异无统计学意义(P>0.05);城市高于农村,差异有统计学意义(P<0.05)。2015—2016年氟牙症患病率、氟牙症指数高于2005年、1995年,差异有统计学意义(P<0.05)。结论广东省12岁人群氟牙症患病率和氟牙症指数虽处于较低水平,但有升高趋势。

Objective To investigate the dental fluorosis status of permanent teeth of a 12-year-old population of Guangdong Province to provide informational support for oral health care in Guangdong.Methods An equal-sized cross-sectional random-sample assessment was carried out among 1 920 urban and rural residents of Guangdong Prov-ince,half male and half female,aged 12 years.We examined the dental fluorosis status of complete permanent teeth crown based on a health survey and the criteria of clinical dental fluorosis from the fourth national oral health survey.The data were analyzed by SAS9.2 to investigate the prevalence and community fluorosis index as well as gender and urban and rural differences,and compared with the prevalence of fluorosis in Guangdong Province in 2005 and 1995.Results In the 12-year-old population,the prevalence of dental fluorosis was 5.05%,and the community fluorosis index was 0.108.There was no significant difference between genders(P>0.05),but there was a significant difference between subjects from urban and rural areas(P<0.05).There were significant differences among prevalence of dental fluorosis and community fluorosis index in 1995,2005 and 2015-2016(P<0.05).Conclusion The prevalence of dental fluorosis and the community fluorosis index of 12-year-old people of Guangdong Province are relatively low,but there is an upward trend.
