目的观察氟保护漆预防乳牙龋病的效果,为本区全面开展学龄前儿童涂氟防龋提供依据。方法选择本区试点幼儿园中班儿童涂布氟保护漆,每半年1次,连续2年共涂布4次,观察涂氟组和对照组患龋率、新增龋均的情况。结果 2年后,对照组的患龋率、新增龋均显著高于涂氟组(P<0.05)。结论学龄前儿童集体涂布氟保护漆能有效预防乳牙龋的发生、发展。
Objective To observe the effect of fluoride protective paint on the prevention of deciduous dental caries and provide evidence for the prevention and treatment of dental fluorosis in preschool children in this area. Methods Children in the pilot nursery in this district were enrolled in this study. Fluorine-protective paint was applied to the children in the pilot nursery school once every six months for 4 consecutive years. The caries prevalence and the number of newly added caries in the fluoride group and the control group were observed. Results Two years later, the caries prevalence and newly added caries in the control group were significantly higher than those in the fluoride group (P <0.05). Conclusion Preschool children ’s collective application of fluoride protective paint can effectively prevent the occurrence and development of deciduous teeth caries.
