【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 status of early childhood caries and caries-related factors for 3 years old children in the Haidian District of Beijing. 【Methods】 The investigation was involved in 588 children of 3 years old form 12 preschool in the Haidian District in Beijing. Their caries were examined and questionaire was provided by their parents. 【Results】 The prevalence of early childhood caries was 47.6%.The mean dft score was 2.20. The children with dft value greater than 3 occupy 26% of the entire examples whereas the number of their dft was 76% of the total caries. Logistic regression analysis showed that the feeding habits, the level of saliva mutans streptococci and the duration of feeding were significant. 【Conclusions】 3 years old children who have just entered kindergarten have a high rate of early childhood caries and low rate of treatment. A few children have a higher risk of early childhood caries and more attention should be need to them, check for them as soon as possible, meanwhile do a better job in prevention.
