集居儿童氟化泡沫防龋一年效果分析

Analysis of the effect of fluoride foam on dental caries in kindergarten children.

目的:在集居儿童中使用氟化泡沫防龋,分析其对乳牙患龋率和龋均的影响。方法:将城区条件相近的两个幼儿园随机分成实验组和对照组,对两个幼儿园的儿童从小班开始均进行良好的口腔卫生宣教,对实验组幼儿园进行一年二次的"莱可丽"氟化泡沫防龋。结果:实验组幼儿园观察对象91人,入园体检时患龋人数61人,患龋率67.03%,龋均4.86;经一年干预后患龋人数65人,患龋率71.43%,龋均5.87;新发龋人数4人,新发龋率10.33%,新增龋均1.02。对照组幼儿园观察对象186人,入园体检时患龋人数132人,患龋率70.97%,龋均4.89;一年后患龋人数157人,患龋率84.41%,龋均7.98;新发龋人数25人,新发龋率46.30%,新增龋均3.03。实验后两组在患龋率及龋均P<0.05。结论:使用氟化泡沫可明显降低患龋率及龋均。

[Objective]The purpose of this study was to assess the preventive effects of fluoride foam on prevalence of dental caries and mean dmft of children in kindergarten.[Method]27children aged 3 years old from 2 kindergarten were assigned to a fluoride foam group and a control group.Two group were same received good oral health education since first year.In fluoride foam group all children were received Laclade fluoride foam application twice' a year.[Result]91 objects in experimental kindergarten group,among which 61 children have dental caries in the medical examination when enrolled in.the prevalence of dental caries is 67.03%,mean dmft is 4.86.After one year of applying the fluoride foam,65 children have dental caries.The prevalence of dental caries is 71.43%,mean dmft is 5.87.The number of increased sufferers is 4.The new prevalence of dental caries is 10.33%,mean dmft increased is 1.02.On the contrast,186 objects in the other group among which 132 children have dental caries when they entered the kindergarten.The prevalence of dental caries is 70.97%,mean dmft is 4.89.After one year of treating,the number of children who got dental caries islS7,the prevalence of dental caries is 84.41%,and mean dmft is 7.98.The number of increased sufferers is 25,and the new prevalence of dental caries is 46.30%,mean dmft increased is 3.03.From the above,we can see that the information of the prevalence of dental caries and the difference of mean dmft we gathered in the study is statistical importance.[Conclusion]The employing of the fluoride foam can obviously reduce the prevalence of dental caries and mean dmft.
