目的对学龄前儿童进行局部涂氟防龋,预防儿童乳牙龋病的发生;同时与氟化泡沫防龋进行对比观察,了解二者的防龋临床效果。方法选定两所幼儿园,各随机抽取3~5岁儿童200名,分为对照组和实验组。实验组对儿童进行乳牙局部涂氟防龋(选用多乐氟氟化钠护齿剂);对照组进行氟化泡沫防龋,对预防乳牙龋病的儿童进行临床观察,干预时间为1年,每半年进行1次防龋治疗。采用SPSS 22.0软件对数据进行统计分析,以龋病发病率和新增龋面作为统计指标。结果实验组与对照组相比,两组儿童患龋率虽没有明显的下降,但实验组龋面增加较对照组少,两组相比,差异有统计学意义(P<0.01)。结论使用局部涂氟与氟化泡沫防龋作用对比,局部涂氟对龋齿增加的控制更有效。
Objective To prevent fluoride decay in children pre-school children, to prevent the occurrence of deciduous teeth decay in children. At the same time, we compared the anti-decubitus with fluorinated foam to find out their anticaries effect. Methods Two kindergartens were selected, and 200 children aged 3 ~ 5 years were randomly selected and divided into control group and experimental group. The experimental group of children with primary deciduous fluoride tooth decay caries (selected Dofluor fluoride fluoride dental care agent); control group fluoridation foam caries, prevention of deciduous dental decay in children clinical observation, the intervention time of 1 year, Anti-caries treatment once every six months. The data were analyzed by SPSS 22.0 software. The incidence of dental caries and the newly added caries surface were used as statistical indicators. Results Compared with the control group, the caries prevalence of the two groups was not significantly decreased in the two groups, but there was less caries in the experimental group than in the control group. There was significant difference between the two groups (P <0.01). Conclusion The use of topical fluoridated fluoridated foam to prevent dental caries, topical fluoridation is more effective in controlling the increase of dental caries.
