摘要
目的了解广东省12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岁城乡常住人口720人,男女各半。按照《第三次全国口腔健康流行病学调查方案》中临床检查牙列状况的检查方法和标准,使用CPI探针检查全口恒牙牙冠龋病情况。数据采用SAS8.1软件统计,计算出患龋率、龋均。结果12岁人群患龋率为33.19%、龋均为0.61。患龋人中有14.23%曾经治疗,龋齿充填率为13.76%。龋均和患龋率在城乡和性别的差异无统计学意义。结论广东省12岁人群龋病状况处于“很低”等级水平,但大部分龋齿未得到治疗。
Objective To investigate the current status of caries in population at the age of 12 years in Guangdong province, thus to provide scientific basis for the establishment of oral health care policies in Guangdong. Methods An equal-sized stratified multi-stage randomly sampling design was applied to obtain a provincially representative sample group consisted of 720 Guangdong residents aged at 12 years old, with a gender ratio of half to half. The caries on the crowns of permanent teeth were assessed according to The Guideline for the 3rd National Oral Health Survey, thereafter the caries rate and decayed, missing and filled tooth （DMFT） of permanent teeth were calculated. The data obtained were analyzed using SAS package. Results In the cohort aged 12, the caries rate was 33.19%, with a DMFT of 0.61. 14.23% of the involved children had been given dental treatments while 13.76% of the caried teeth had been filled. Neither gender difference nor geographical divergence of caries rate and DMFT was illustrated. Conclusion The data suggested that caries remained at a ＂very low＂ level among 12-years-old Guangdong population, with most of the involved teeth, however, not treated.
