Analysis of decidous dental caries among 3～6 years old preschooler in Beijing city

目的了解北京市3~6岁学龄前儿童乳牙龋患病情况,为龋病防控提供参考依据。方法随机选取2016年9月至2017年6月北京市48所幼儿园的6820名3~6岁学龄前儿童为调查对象。参照第三次全国口腔健康流行病学调查方案,进行龋病检查,记录龋病情况并对其进行分析。结果北京市3~6岁学龄前儿童总患龋率为55.60%,龋均为2.67,龋齿充填率为1.86%。3、4、5、6岁年龄组儿童的患龋率分别为46.79%、54.53%、60.13%、65.40%,组间比较差异均具有显著性(P<0.05);龋均分别为1.69、2.47、3.07、4.15,组间比较差异均具有显著性(P<0.05);龋齿充填率分别为1.62%、1.21%、1.86%、2.75%,组间比较差异均具有显著性(P<0.05)。男童龋均和患龋率均显著低于女童(P<0.05)。公办幼儿园儿童龋均和患龋率均显著低于民办幼儿园儿童(P<0.05),龋齿充填率显著高于民办幼儿园儿童(P<0.05)。结论北京市3~6岁学龄前儿童患龋率和龋均较高,龋齿充填率较低;女童、民办幼儿园儿童及5~6岁儿童为龋病高发群体,应重点加强口腔健康知识宣教,进行早期防治。

Objective To investigate deciduous dental caries among3~6years old preschooler in Beijing city,and provide reference basis for caries disease prevention and control.Method6820preschooler aged3~6years old from48kindergarten in Beijing were randomly selected as the research objects from September2016to June2017.The dental cavities check by the third national oral health epidemiological survey requirements,record caries disease situation and analyzed.Result The dental caries rate of preschooler aged3~6years old in Beijing city was55.60%,the mean dmft was2.67,the filling rate was1.86%.The dental caries rate of3,4,5,6age group were46.79%,54.53%,60.13%and65.40%respectively,the differences were statistically significant(P<0.05);the mean dmft score were1.69,2.47,3.07and4.15respectively,the differences were statistically significant(P<0.05);the filling rate were1.62%,1.21%,1.86%and2.75%respectively,the differences were statistically significant(P<0.05).The dental caries rate and the mean dmft in boys were significantly lower than girls,(P<0.05).The dental caries rate and the mean dmft of public kindergarten children were significantly lower than private kindergarten children(P<0.05),the filling rate was significantly higher than that of private kindergarten children(P<0.05).Conclusion The dental caries rate and the mean dmft were higher among3~6years old preschooler in Beijing city,and had low filling rate.Children aged5~6years,girls and private preschool children are the high-risk groups,should strengthen oral health knowledge education and early prevention
