目的 调查张家港市3岁儿童乳牙患龋现状及相关危险因素,为开展托幼机构儿童口腔保健工作提供依据。方法 采用分层随机整群抽样的方法,抽取张家港市 1 997 名3岁儿童进行龋病检查及龋活跃性检测,同时对儿童家长进行问卷调查,对乳牙龋的相关因素进行logistics回归分析。结果 张家港市3岁儿童的乳牙患龋率为 49.12%,龋均为0.0(0.0,3.0),患龋率和龋均在男女间差异无统计学意义(χ2=1.743,P=0.194;Z=1.229,P=0.219),但在不同龋活性分组患龋率和龋均有统计学差异(χ2=245.866,P＜0.001;χ2=281.827,P＜0.001)。多因素 logistics 回归分析显示,开始刷牙年龄晚、睡前进食甜食频率高和日常生活由老年人照顾是患龋的危险因素。结论 张家港市3岁儿童防龋形势严峻,针对乳牙龋的危险因素,家庭与托幼机构需要联合开展早期多种防龋措施。
Abstract
Objective To explore the prevalence of deciduous teeth caries among 3-year-old children and its related risk factors in Zhangjiagang City,so as to provide basis for oral health care of children in kindergartens. Methods The stratified random cluster sampling method was used to select 1997 children aged 3 years in Zhangjiagang City for caries examination and caries activity detection,meanwhile questionnaire survey was conducted among their parents.Logistic regression analysis was used to explore the factors related to deciduous teeth caries. Results The caries rate of deciduous teeth of 3-year-old children in Zhangjiagang City was 49.12%,and the dmft was 0.0 (0.0,3.0).There was no significant difference between male and female (χ2=1.743,P=0.194;Z=1.229,P=0.219),but there were significant differences in caries incidence and DMFT in different caries activity groups (χ2= 245.866,P < 0.001;χ2=281.827,P＜0.001).Multivariate logistic regression analysis showed that the late start of brushing,the high frequency of eating sweets before going to bed,and the care of the elderly in daily life were risk factors for caries. Conclusion The caries prevention situation of 3-year-old children in Zhangjiagang City is severe.In view of the risk factors of deciduous tooth caries,families and childcare institutions need to jointly carry out various early anti-caries measures.
