目的探讨在托儿所就诊时使用氟化物涂膜是否能降低美国印第安人儿童早期龋病高危人群的患龋率。方法这是一项在美国印第安人社区进行的观察性研究。从2002年开始，所有儿童在9个月、12个月、15个月、18个月、24个月和30个月的托儿所接受氟化物清漆涂抹。2003年的Head Start班作为历史对照，2004和2005年的学生接受了越来越多的氟化物清漆治疗。所有从2003年到2005年进入Head Start的儿童都进行了牙科检查，以确定存在的腐烂、缺失和填充表面(DMF)的数量。每个儿童的DMF数量与接受氟化物清漆治疗的数量相关。结果接受4次或4次以上治疗的儿童有15.5个DMF(95%可信区间10.8~20.4)，而没有接受氟化物涂膜治疗的儿童有23.6个DMF(95%可信区间19.5~25.8)，总体龋病减少35%。接受1、2或3次治疗的儿童与没有使用氟化物清漆的儿童相比，DMF没有显著差异。结论在托儿所就诊时使用氟化物涂膜可以减少美国印第安人儿童早期龋病的发生。应该考虑让美国印第安人和阿拉斯加土著儿童在探视儿童时更容易获得氟化物清漆。这些发现可能适用于其他儿童早期龋齿风险增加的儿童。
Objectives To determine if fluoride varnish applied at well child care visits would decrease the prevalence of dental caries in a group of American Indian children at high risk for early childhood caries. Methods This was an observational study in an American Indian community. Starting in 2002 all children received fluoride varnish applications at well child care visits at 9, 12, 15, 18, 24 and 30 months. The Head Start class of 2003 served as historical controls and students in 2004 and 2005 had increasing number of fluoride varnish treatments. All children entering Head Start from 2003 to 2005 had dental exams to determine the number of decayed, missing and filled surfaces (dmfs) present. The number of dmfs for each child was correlated with the number of fluoride varnish treatments received. Results Children with 4 or more treatments had 15.5 dmfs (95% CI 10.8-20.4) versus children with no fluoride varnish treatments who had 23.6 dmfs (95% CI 19.5-25.8) for a 35% decrease in overall caries. Children who received 1, 2 or 3 treatments showed no significant difference in dmfs when compared with children who had no fluoride varnish applications. Conclusions Fluoride varnish applied at well child care visits can reduce early childhood caries in American Indian children. Consideration should be given to making fluoride varnish more available to American Indian and Alaska Native children at well child visits. These findings may be applicable to other children who are at increased risk for early childhood caries.
