摘要
〕目的:比较氟化物对儿童龋病的预防作用。方法:对饮水氟含量1.578×10-5mol/L低氟区7岁~8岁学生557名,以学生班为单位分为氟片组与对照组,进行群体防龋试验。结果:试验3年后,氟片组与对照组比较,龋均、龋面均的降低率分别为45.00%、56.14%,对第一恒磨牙,龋均、龋面均降低率分别为40.54%、50.00%,龋齿都发生在第一恒磨牙的点隙窝沟处。对照组前牙及双尖牙龋患较低,氟化物对前牙光滑面龋的预防效果仍有待继续观察。结论:氟化物对窝沟龋有一定的防龋作用,但较窝沟封闭剂的防龋效果差。对于儿童龋齿的预防,如果将氟化物与窝沟封闭同时应用,将会取得最佳的效果。
Objective:To study the preventive effects of fluoride on dental caries.Mehod:The comparative method was carried out in 557(299 male,258 female) subjects aged 7 to 8 years old living in a fluoride deficient area(1.578×10 5 mol/L in the drinking water).The subjects were divided into two groups.In the tested group (440 children) 1.0mg of fluoride tablet was given to each child orally per day.In the control group(117 children) no fluoride was given.Results:The results demonstrated an overall reduction of 45% DMFT and 56.14% DMFS in the fluoride treated group,40.54% DMFT and 50% DMFS in the first molars.Conclusion:Fluoride tablet is effective in the prevention of dental caries in Chinese children.
