摘　　要：目的探讨以幼儿园为基础开展的局部用氟干预活动对5~6岁儿童早期乳牙龋病(early childhood caries,ECC)患病率的影响,为促进儿童口腔健康提供参考。方法采用现况调查的方法,两阶段分层整群抽样方法抽取西安市8所幼儿园564名儿童,回顾调查局部用氟干预时间和材料。口腔检查儿童龋失补牙数和软垢指数。家长问卷调查儿童基本人口学资料,家庭和社会因素(家长最高学历、家庭上月实际收入等),儿童刷牙相关行为(开始刷牙年龄、刷牙频次等),饮食情况(进食甜点心的频率、睡前进食甜食),12月内是否有过牙齿不适及就医情况。结果儿童ECC患病率为63.8%,龋均为(3.00±3.33)。294名参加局部用氟的儿童人均干预(4.83±1.00)次,其中33.7%只施用含氟涂料,66.3%交替施用含氟涂料和氟化泡沫。施用含氟涂料、含氟涂料和氟化泡沫、没有局部用氟的儿童ECC患病率分别为53.5%,63.1%,68.1%,龋均分别为(2.45±3.42)(2.83±3.04)(3.32±3.47),差异有统计学意义(χ2/F值分别为6.77,7.08,P值均<0.05)。二元Logistic回归分析显示,施用含氟涂料与发生ECC呈负性相关(OR<1),开始刷牙时间晚、进食甜点心频率高、口腔卫生水平低、12个月内看过牙医与发生ECC呈正性相关(OR值均>1)。负二项回归分析局部用氟干预未对龋均产生影响(P值均>0.05)。结论以幼儿园为基础开展的局部用氟干预龋病效果有限。需要有针对性开展健康教育,鼓励家长及早对儿童开始饮食、刷牙行为干预。Objective To explore the effect of a preschool-based fluoride application on early childhood caries( ECC) prevention among 5 to 6-years old children in two urban districts of Xi’ an.Methods This cross-sectional study was conducted by using a two-stage cluster method. A total of 564 children aged 5 to 6-years old from eight preschools were recruited for this study.Each participant was assessed dental caries and debris index. Time and materical for topical fluorine application was recorded. Parents/guardians completed a structured self-administered questionnaire, which included demographic, family and social factors( educational level of parents,household monthly income, etc). Children’ s oral health related behaviors( age to start brushing, brushing tooth frequency, parents supports in child’ s teeth brushing, and whether use fluoride toothpaste);dietary habit( frequency of dessert, desert before sleep, dental discomfort within 12 months, visits to dentist within 12 months). The status of dental caries was shown in the form of the mean dmft and the prevalence of ECC. Results The prevalence of ECC and mean dmft of children was63.8% and( 3.00±3.33) respectively. Among the 294 children aged 5-6 years old, the average intervention time was( 4.83±1.00),33.7% of the children only applied fluorine vanish, 66.3% of the children applied fluorine vanish and fluorine foam. The prevalence of ECC was 53.5%, 63.1% and 68.1% in the children who applied fluorine vanish, fluorine vanish and fluorinated foam, no fluoride, respectively. The mean dmft was( 2.45±3.42)( 2.83±3.04) and( 3.32±3.47), respectively, with statistically significant differences( χ2/F = 6.77, 7.08, P<0.05). According to binary Logistic regression equation analysis, the application of fluorine vanish was negatively associated with the prevealence of ECC( OR<1.00). High frequency of dessert intake, low degree of oral hygiene and late start of brushing teeth was positively associated with deciduous teeth caries( OR>1.00). Negative binomial regression a
