摘　　要：目的掌握长沙市雨花区3〜5岁儿童龋病状况及Cariostat法龋活性检测结果,为制定学龄前儿童防龋措施提供依据。方法随机选取长沙市雨花区6所幼儿园1032例3〜5岁儿童进行口腔健康检查。随机抽取6个大班、6个中班及6个小班565例儿童进行Cariostat法龋活性检测。结果1032例儿童中患龋者626例,患龋率为60.66%,龋均为2.87±3.67,龋齿充填率为8.53%。上颌中切牙患龋率最高(37.89%),其次是下颌第二乳磨牙(32.56%)、下颌第一乳磨牙(32.36%)。不同年龄组患龋率比较差异有统计学意义(χ^(2)=9.231,P<0.05),5岁儿童患龋率最高(66.50%)。1032例儿童按乳牙龋、失、补牙数(dmft)值分为4组,无龋组人数最多;中龋组人数最少。1032例儿童龋失补牙数共2959颗,高龋组儿童龋失补牙数最多,达1861颗,占龋失补牙总数的61.89%。565例儿童按龋活性试验(简称CAT)分析显示:不同CAT分度患龋率不同(χ^(2)=27.390,P<0.05),高度组患龋率最高(90.48%)。CAT值与龋均呈正相关(r=0.261,P<0.05)。结论长沙市雨花区3〜5岁儿童龋齿发生率为60.66%。Cariostat法可较真实地反映儿童患龋情况,有助于筛选儿童龋病易感人群。Objective To investigate influencing factors of dental caries among 3 to 5-year-old children in the Yuhua District of Changsha by Cariostat detection and provide evidence to prevent caries.Methods 1032 children aged 3-5 years old from 6 kindergartens in Yuhua District of Changsha were randomly selected for oral health examination.565 children in 6 large classes,6 middle classes and 6 small classes were randomly selected from 6 kindergartens were perfected caries activity test(CAT)by Cariostat detection.Results Among 1032 children,626 had caries,the caries rate was 60.66%,the caries was 2.87±3.67,and the caries filling rate was 8.53%.The caries rate of maxillary central incisors was the highest(37.89%),followed by mandibular second primary molars(32.56%)and mandibular first primary molars(32.36%).There was significant difference in caries rate among different age groups(χ^(2)=9.231,P<0.05).The caries rate of 5-year-old children was the highest(66.50%).1032 children were divided into 4 groups according to dmft(decayed,missing,filled teeth)value,and the number of caries free group was the largest;the number of caries in the middle caries group was the least.The number of missing teeth in 1032 children with caries was 2959.The number of missing teeth in the high caries group was the most,up to 1861,accounting for 61.89%of the total number of missing teeth.The analysis of 565 children by CAT showed that the caries rate was different in different CAT grades(χ^(2)=27.390,P<0.05).The caries rate in the high-risk group was the highest,90.48%.The CAT value was positively correlated with caries(r=0.261,P<0.05).Conclusions The incidence of dental caries in children aged 3-5 years in Yuhua District of Changsha was 60.66%.Cariostat method can truly reflect the situation of caries in children and is helpful to screen the population susceptible to caries in children.
