Investigation and analysis on the prevalence of deciduous teeth caries among kindergarten children in Shijingshan district of Beijing in 2018

目的了解北京市石景山区幼儿园儿童口腔健康状况,为儿童龋病综合防治工作提供参考依据。方法对北京市石景山区56所幼儿园的3~6岁儿童进行口腔检查,对不同年龄组的患龋率和龋均进行比较。结果2018年北京市石景山区56所幼儿园14497名儿童完成了口腔检查,其中共有患龋儿童9184名,患龋率63.3%,龋均(3.84±4.03),患龋率、龋均随年龄增长而逐年增加。其中3、4、5、6岁年龄组儿童患龋率分别为51.5%、63.4%、71.6%、72.5%,龋均分别为(2.53±3.32)、(3.77±4.02)、(4.72±4.20)、(5.10±4.23),充填率分别为13.77%、19.51%、24.23%、27.49%,患龋率和龋均在不同年龄组间差异有统计学意义,随年龄增长而增长。结论北京市石景山区幼儿园儿童乳牙龋病患病率较高,龋齿充填率较低。应进一步加强群体儿童口腔宣教与综合防治工作,提高儿童家长对乳牙龋病的正确认识。

Objective To investigate the oral health status among children in the kindergartens in Shijingshan District in Beijing,to provide reference for comprehensive prevention and treatment of children’s dental caries.Methods Oral examination was carried out on children aged 3-6 years old in 56 kindergartens in Shijingshan District of Beijing,and the incidence and prevalence of dental caries in different age groups were compared.Results In 2018,14497 children completed oral examination.Among them,9184 children were diagnosed with caries.The prevalence of caries was 63.3%.The average of decayed-missing-filled tooth(DMFT)was 3.84±4.03.The prevalence of caries and the average of DMFT increased with age.The prevalence rates of dental caries in children aged 3,4,5 and 6 years old were 51.5%,63.4%,71.6%and 72.5%,respectively,and the DMFT was(2.53±3.32),(3.77±4.02),(4.72±4.20)and(5.10±4.23),respectively.The filling rate of caries teeth was 13.77%,19.51%,24.23%and 27.49%,respectively.The incidence of dental caries and DMFT were significantly different among different age groups.Conclusion Children in Shijingshan district have high deciduous dental caries rate and low caries filling rate.Therefore,oral health education,comprehensive prevention and treatment of group children should be further strengthened.The correct understanding of deciduous dental caries of their parents should be improved.
