目的：对深圳市南山区3～6岁儿童乳牙龋齿患病现况进行分析，为制定乳牙龋齿预防措施提供科学依据。方法将2010—2014年深圳市南山区180余家幼儿园共计175945人次儿童进行口腔检查，并对龋齿的流行特征进行分析。结果深圳南山区托幼机构儿童2010—2014年，5年平均龋齿患病率为44．3％，5年来学龄前儿童龋齿患病率持平（P＝0．696）。2010—2014年学龄前儿童龋齿患病率随年龄增长而增高（龋齿患病率3～＜4岁为24．8％，4～＜5岁为38．7％，5～6岁为54．5％，P＜0．001），区级／合格幼儿园龋齿患病率明显高于省／市级幼儿园（P＜0．001）。结论随着年龄增长，学龄前儿童龋齿患病率升高，等级低的幼儿园龋齿患病率高于等级高的幼儿园。预防龋齿，要从婴儿抓起，采取综合预防措施，从而降低龋齿发病率。

ABSTRACT:Objective To analyze the prevalence of deciduous dental caries in kindergarten chil-dren aged 3-6 years in Nanshan district of Shenzhen city,and to provide a scientific basis for the development of caries preventive measures.Methods A total of 175 945 oral examination records of kindergarten children(2010-2014)were summarized and epidemiological characteristics of dent-al caries were analyzed.Results The 5-year prevalence of dental caries was 44.3% in kindergar-ten children in Nanshan district of Shenzhen city in 2010-2014.No changes in the prevalence of dental caries from 2010 to 2014(P=0.696).However,the prevalence of dental caries increased with age(24.8% in children aged 3-<4 years,38.7% in children aged 4-<5 years,and 54.5% in children aged 5-6 years,P<0.001).The prevalence of dental caries in district level kindergartens was significantly higher than that in provincial/municipal level kindergartens(P<0.001).Conclu-sion The prevalence of dental caries increases with age,and the prevalence in district level kin-dergartens is higher than that in provincial/municipal level kindergartens.Therefore,the preven-tion of dental caries should be initiated during infant stages and comprehensive preventive meas-ures should be taken to reduce the prevalence of dental caries.
