多乐氟在预防脑瘫低龄儿童龋病中的疗效观察

目的 评价涂氟对德州地区3～5岁脑瘫低龄儿童龋病的预防效果,为脑瘫儿童乳牙龋病预防提供依据。方法 2018年1月-2020年1月以德州市9家脑瘫儿童康复机构中年龄在3～5岁的脑瘫儿童107人作为研究对象,将其随机分为2组。实验组脑瘫儿童(54例1 080颗牙)每半年涂氟1次,对照组(53例1 060颗牙)为空白组,同时每半年对监护人进行口腔健康教育1次,共干预4次;对比干预效果。结果 2年后,实验组和对照组脑瘫儿童患龋率差异无统计学意义(χ²＝2.256,P>0.05),但实验组龋病发病率(7.41% vs.20.75%)、龋均(2.41±2.02 vs.3.47±2.35)、乳前牙龋病发病率(7.41% vs.12.89%)均低于对照组,差异有统计学意义(χ²＝3.953,t=-2.512,χ²＝10.615,P<0.05)。结论 周期性应用多乐氟能降低低龄脑瘫儿童的乳牙龋病发病率和新增龋均,值得在脑瘫儿童中推广使用。

Effect of Duraphat on the prevention of dental caries in early childhood with cerebral palsy

Objective To evaluate the preventive effect of Duraphat on dental caries among children with cerebral palsy(CP) aged 3-5 years in Dezhou,so as to provide basis for prevention of primary tooth caries in children with cerebral palsy. Methods A total of 107 children with cerebral palsy aged 3-5 years were selected from 9 rehabilitation institutions for children with cerebral palsy in dezhou city from Januany 2018 to January 2020 and were randomly divided into 2 groups.Children with cerebral palsy in the test group (54 cases with 1 080 teeth) were treated with fluoride varnish once every six months,while the control group (53 cases with 1 060 teeth) was blank group.At the same time,oral hygiene instruction was conducted for the guardian semi-annually for 4 times.Then the effect of intervention was compared between the two groups. Results After two years,there was no significant difference in caries rate between the two groups (χ²=2.256,P>0.05).However,there were statistically significant differences in the the incidence of dental caries(7.41% vs. 20.75%), dmft(2.41±2.02 vs.3.47±2.35) and the incidence of anterior caries(7.41% vs. 12.89%) (χ²=3.953,t=-2.512,χ²=10.615,P<0.05). Conclusion The use of Duraphat can reduce the caries incidence rate and dmft increments of primary teeth in early childhood with cerebral palsy and is worthy to be used widely in Dezhou district.
