云南省安宁市3~6岁儿童乳牙龋病状况及影响因素分析

Dental Caries Status and Associate Factors among 3-6-yearold Children in Anning City,Yunnan Province

目的 了解安宁市3~6岁儿童龋病患病状况,检测龋活跃性指数,分析3~6岁儿童龋病发生的相关因素。方法 2023年5月至2023年6月在云南省安宁市采用分层随机整群抽样的方法,对安宁市学龄前儿童进行口腔健康检查和龋活跃性检测(Cariostat),并请家长填写问卷调查表,采用Logistic回归分析方法,分析与乳牙龋病相关的因素。结果 共有3 070名3~6岁儿童参与研究,安宁市3~6岁儿童患龋率为65.8%,龋均为2.0(0.0,7.0)。患龋率(χ^(2)=227.134,P <0.001)和龋均(χ^(2)=331.844,P <0.001)在不同龋病活跃性分组间差异有统计学意义。多因素回归分析显示,儿童所在街道、性别、刷牙方式、开始刷牙的年龄、牙疼痛经历和看牙经历、进食糖果频率、龋态检测值分组与乳牙龋的发生差异有统计学意义(P <0.05)。结论 云南省安宁市3~6岁儿童患龋情况严重,乳牙龋病患龋率高,需要引起重视。龋活跃性检测(Cariostat)可以有效评估儿童患龋风险,早期识别龋高风险人群,及早进行防治工作。龋齿的发生与家庭社会经济地位和口腔健康相关行为有关,需加强相关政策和支持措施来降低儿童的患龋率,预防龋病的发生。

Objective To investigate caries status of children aged 3-6 in Anning City,evaluate the activity index of caries,and analyze the factors related to caries occurrence in children aged 3~6.Methods A stratified random cluster sampling method was employed to select 3-to-6-year-old children in Anning City for oral health examination and caries activity detection(Cariostat)from May 2023 to June 2023.Questionnaires were filled by parents.Logistic regression analysis was used to analyze the factors associated with caries in primary dentition.Results A total of 3070 children aged between 3 to 6 years old participated in the study.The caries rate of children aged 3~6 in Anning City was 65.8%,with an average dmft of 2.0(0.0,7.0).There were statistical differences in caries rate and dmft scores(χ^(2)=227.134,P<0.001;χ^(2)=331.844,P<0.001)among different caries activity groups.Multivariate regression analysis showed that the location where children reside,gender,brushing method,age of starting brushing,experience of toothache and dental visits,frequency of eating candy,grouping of caries te-st values,and differences in the occurrence of deciduous tooth caries have statistical significance.Conclusion The situation of dental caries in children aged 3~6 in Anning City,Yunnan Province,is serious.The caries rate of primary teeth is high and needs to be taken seriously.Cariostat testing can effectively assess the risk of dental caries in children,identify high-risk groups early,and carry out prevention and treatment work promptly.The occurrence of dental caries is related to family socioeconomic status and oral health-related behaviors,so it is necessary to strengthen relevant policies and support measures to reduce the caries rate in children and prevent the occurrence of dental caries.
