目的：调查北京市3~5岁儿童乳牙患龋状况,分析各区县之间患病状况的差异。方法2013年进行的横断面研究,调查3~5岁儿童333344名。龋齿诊断参照世界卫生组织流行病学调查标准,以牙为单位记录成洞的龋坏,即龋均指数。结果3、4和5岁年龄组儿童患龋率分别为40．3%,52．2%和60．3%；龋均分别为1．69、2．45和3．06；充填率分别为7．9%、13．7%和18．9%。儿童的患龋率和龋均随年龄正向增长,回归模型拟合度在96%以上。3个年龄组儿童的患病率、龋均和充填率在不同区县之间的差异有统计学意义( P<0．001)。结论北京市3~5岁儿童乳牙龋病的患病率依然较高,患病程度处于较重水平,龋病发病年龄早,区县之间存在差异显著。提示乳牙龋的防治负担重,应尽量从低龄幼儿做起。

Objective To investigate the status and distribution of early childhood caries ( ECC ) in 3-5 years children in Beijing. Methods Cross-sectional study was conducted in 2013. Oral health examination was performed in 333344 children aged 3-5 years. Only cavitied caries ( dmft ) were recorded according to the WHO oral health survey method. Results The prevalence of ECC in 3, 4 and 5 years-old children was 40. 3%, 52. 2% and 60. 3% and the dmft was 1. 69, 2. 45 and 3. 06, and the filling rate of caries teeth was 7. 9%, 13. 7% and 18. 9%, respectively. The caries prevalence and dmft were positively correlated to age. The regression model fitting degree was over 96%. The difference of dental caries prevalence, dmft and filling rate among the three age-groups of children and among various districts was significant ( P < 0. 001 ) . Conclusion The ECC level for preschool children in Beijing was still high. Oral health promotion was recommended to start from the earlier stage of life cycle.
