2005年广东省5岁人群乳牙龋病抽样调查报告

目的 了解广东省5岁人群乳牙龋病状况,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5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探针检查全口乳牙牙冠龋病情况.计算出患龋率、龋均.结果 5岁组人群乳牙患龋率为67.78%、龋均为4.10.患龋人中有3.28%的人曾经治疗,龋齿充填率为1.09%.龋均和患龋率在城乡的差异无统计学意义,男性与女性比较差异有统计学意义.结论 5岁儿童乳牙龋齿较严重, 98.81%龋齿未经治疗,是龋病预防的重点人群.与1995年比较,患龋率和龋均有下降.

The Deciduous Caries in a 5 Years Old Guangdong Cohort: A Sampled Investigation

Objective To investigate the current status of deciduous caries in population at the age of 5 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 5 years old,with a gender ratio of half to half.The caries on the crowns of deciduous 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 deciduous teeth were calculated.The data obtained were analyzed using SAS package.Results In the group of aged 5,the caries rate was 67.78%,with a dmft of 4.10.Only 3.28% of the involved children had been given dental treatments while 1.09% of the caried teeth had been filled.A significant gender difference was illustrated but no significant geographical divergence between urban and countryside was found.Conclusion The data suggested that deciduous caries remained a serious problem among 5-years-old population,which should be the key target of caries prevention,although the decline of both dmft and caries rate was observed in 2005 when compared with those in 1995.
