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。
Abstract
Objective To explore the effect of fluoride varnish in preventing caries of primary teeth caries,and provide scientific basis for the establishment of oral health care. Method sTotally 496 children in middle group from 6 kindergartens in Changning district were voluntarily divided into experience group and control group.The children in experience group were taken the oral examination and used the fluoride varnishes every 6 months.The others in control group were taken the oral examination twice a year only.The data of caries incidence and new decayed missing and filledtooth (DMFTS) were analyze as the statistical index. Results Two years later,the caries incidence had significant differences between the two groups(P<0.05),the experience group was much lower than the control group.The new DMFTS was significant lower in the experience group. Conclusion The application of fluoride varnish can effectively prevent deciduous teeth caries spreading and keep mouth healthy.
