2005年云南省5岁人群乳牙龋病抽样调查报告

目的 调查2005年云南省5 岁人群乳牙龋病状况,为云南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,抽取云南省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>中检查方法和标准,使用CPI探针检查全口乳牙牙冠龋病情况,统计患龋率、龋均.结果 5岁组人群乳牙患龋率为65.69%、龋均为3.68,龋齿充填率为3.47%.患龋率和龋均在城乡有差异,差异有统计学意义;男性与女性比较差异无统计学意义.结论 与1995 年云南省的调查结果比较, 2005年云南省5 岁儿童乳牙患龋率和龋均有所下降,龋齿较为严重,依然是龋病预防的重点人群.

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

Objective To investigate the current status of deciduous caries in population at the age of 5 in Yunnan province,thus to provide scientific basis for the establishment of oral health care policies in Yunnan.Methods An equalized stratified multistage randomly sampling design was applied to obtain a provincially representative sample group consisted of 720 Yunnan 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 SPSS package.Results In the group of aged 5,the caries rate was 65.69%,with a dmft of 3.68.3.47% of the caried teeth had been filled.A significant difference between urban and countryside but no significant gender difference 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.
