目的对比氟保护漆与氟化泡沫预防学龄前儿童龋病的效果。方法采用整群抽样方法,随机抽取柳州市区3所幼儿园的3岁儿童366例,随机分为3组,氟保护漆组126例,氟化泡沫组124例,空白对照组116例。氟保护漆组及氟化泡沫组分别给予全口乳牙涂布氟保护漆、氟化泡沫;空白对照组仅进行口腔卫生宣教。两年后观察干预效果。结果干预前3组的患龋率及患龋数比较,差异无统计学意义(P>0.05),干预后氟保护漆组患龋率为54.45%,低于氟化泡沫组的57.02%和空白组的73.68%(P<0.05),新增龋数低于氟化泡沫组、空白组(P<0.05)。结论氟保护漆及氟化泡沫均能有效预防乳牙龋病,氟保护漆防龋效果明显优于氟化泡沫,且操作简便,更适合用于儿童群体防龋。
Objective To compare the effect of fluorinated lacquer and fluorinated foam in preventing caries in preschool children. Methods A total of 366 cases of 3-year-old children from 3 kindergartens in Liuzhou city were randomly divided into three groups randomly. The fluoride protective paint group was 126 cases, the fluorinated foam group was 124 cases, and the blank control group was 116 cases. Fluoride protective paint group and fluorinated foam group were given full-mouth deciduous fluoride-coated fluoride paint, fluoride foam; blank control group only for oral hygiene mission. Two years later observe the effect of intervention. Results There was no significant difference in caries prevalence and number of caries in the three groups before intervention (P> 0.05). The caries prevalence of fluoride protective paint group after intervention was 54.45%, which was lower than that of fluorinated foam group (57.02%) and blank (P <0.05). The number of new caries was lower than that of fluorinated foam group and blank group (P <0.05). Conclusion Fluoride-protective lacquer and fluoridated lather can both effectively prevent deciduous dental caries. The protective effect of fluorinated lacquer is better than that of fluorinated lather, and it is easy to operate and more suitable for the prevention of caries in children.
