摘要:

目的 了解沈阳市儿童乳牙龋病极性化分布情况。方法 2000年随机选取沈阳市10所幼儿园的3 799 名2~5岁乳牙列儿童进行龋病情况调查。计算各年龄组龋失补牙数(dmft)和SiC指数,并将各年龄组人群按dmft 的大小分亚组,统计各亚组人数及平均dmft,以及亚组dmft占总dmft的百分率。结果 儿童龋病分布不均衡,存在两极化现象。其中2岁组dmft≥3的人数占总人数4·5%,dmft占总数的60·0%;3岁组dmft≥3的人数占总数的 13·2%,dmft占总数的69·4%;4岁组dmft≥3的人数占总数的34·4%,dmft占总数的86·6%;5岁组dmft≥3的人数占总数的47·8%,dmft占总数的89·8%。结论 儿童乳牙龋病存在两极化倾向,对龋患高危儿童需要重点预防。

Abstract:

Objective To investigate dental caries polarization in 2-5 year-old children.Methods 3 799 random samples of 2-5 year-old children from attending kindergarten in Shenyang were selected. Means of dmft index and SiC index for each age group were calculated by WHO Collaborating Center. The subjects of each age groupwere further divided into subgroups of differ- ent level of dmft: the dmft of subgroup I was 0, the dmft of subgroup II was 1, the dmft of subgroup III was 2, the dmft of sub- group IVwas equal to or more than 3. The obtained data were analyzed statistically with SPSS 10.0.Results 4.5% of 2-year- old children were carriers of 60.0% of the total dmft in that age group, 13.2% of 3-year-old childrenwere carriers of 69.4% of the total dmft in that age group, 34.4% of 4-year-old children were carriers of 86.6% of the total dmft in that age group, and 47.8% of 5-year-old children were carriers of 89.8% of the total dmft of that age group.Conclusion This study supports the assertion that a small percentage of personswith high dental caries rate and a large percentage of caries-free persons of early child- hood caries.
