摘　　要：目的评价幼儿园全托及日托模式下应用氟保护漆预防乳牙龋病的效果。方法选择广州市6所幼儿园3周岁儿童850名,分为2组,全托组450名,日托组400名。从2006年10月起每年对2组儿童行龋齿检查和充填。从2006年11月起每6个月为2组儿童涂氟保护漆并进行口腔卫生宣教,共4次。比较2组涂氟前后的龋均、患龋率和龋齿充填率。结果涂氟干预前2组龋均(t=0.57,P=0.67)、患龋率(χ2=0.09,P=0.78)和龋齿充填率(χ2=0.06,P=0.88)的差异均无统计学意义。全托组1年和2年后的患龋率分别为23.13%和32.60%,充填率为32.50%和51.33%;日托组1年和2年后患龋率分别为33.65%和49.22%,充填率为11.50%和22.90%。全托组在干预1年后(χ2=5.76,P=0.02)和2年后(χ2=6.64,P=0.01)的患龋率均低于日托组。结论在全托模式下应用氟保护漆较日托模式取得更好的乳牙防龋效果,全托模式下更多龋齿得到充填。Objective To evaluate the caries preventive efficacy using fluorin protective lacquer in full-time and daycare nursery, school. Methods Eight hundred and fifty 3-year-old children from 6 kindergartens in Guangzhou were selected, including 450 children from fulhime nursery and 400 from day-care group. All the children were applied protective lacquer contained fluorine biannually for 2 years. Results At the beginning of the experiment, there＇ s no evident disparity between the two groups （P 〉0.05）. The incident rates of dental caries were 23.13% in first year and 32.6% in second year of fulhime nursery group compared with 33.65% and 49.22% of day-care group （ P 〈 0.05 ）. Conclusion Applying fluorine protective lacquer could prevent children from dental caries in deciduous teeth evidently and more caries were treated in full-time nursery.
