【目的】了解北京市海淀区3岁儿童婴幼儿龋(early childhood caries,Ecc)患病率及其影响因素,为探索幼儿园集体儿童龋病综合预防模式提供依据。【方法】随机抽取海淀区12所幼儿园588名3岁儿童进行患龋状况调查,并对家长进行问卷调查统,统计分析Ecc发病情况与影响因素间的关系。【结果】本研究3岁儿童Ecc患病率为47.6%,龋均(dft)为2.20,dft>3的儿童占样本量的26%,其龋齿数占样本量龋齿总数的76%;Logistic回归分析结果显示,不良的喂养方式、口腔中唾液的变链细菌水平及母乳喂养时间与Ecc的发生率有相关性。【结论】北京市海淀区刚入园3岁儿童Ecc患病率较高,治疗率低,绝大多数的龋齿集中发生在少部分人身上,提示对龋高危儿童应进行重点监控,及早进行筛查,做好防控工作。
【Objective】 To investigate the prevalence and influential factors of early childhood caries (ECC) in 3-year-old children in Haidian District, Beijing, and to provide basis for exploring a comprehensive preventive model of caries in kindergartens. 【Method】 A total of 588 3-year-old children from 12 kindergartens in Haidian District were investigated for caries status. The parents were surveyed and the relationship between the incidence of Ecc and the influential factors was statistically analyzed. 【Results】 The prevalence of Ecc was 47.6%, the average caries (dft) was 2.20 and the dft> 3 accounted for 26% of the sample size. The number of dental caries accounted for 76% of the total number of dental caries samples. Logistic regression The results of the analysis showed that poor feeding patterns, varying levels of salivary streptococcal bacteria in the oral cavity, and breastfeeding times correlated with the incidence of Ecc. 【Conclusion】 The prevalence of Ecc in 3-year-old children just entering the park in Haidian District, Beijing is high, the treatment rate is low, the majority of dental caries occur in a small number of people, which indicates that the children with high risk of caries should be monitored and monitored as soon as possible Check, do a good job of prevention and control.
