两种窝沟封闭剂预防儿童龋病的效果观察

Observation of preventive effect of Eco-s and SDI Conseal sealant for caries in children

目的对比观察SDI Coseal与Eco-S窝沟封闭剂预防儿童恒磨牙龋病的临床效果。方法 将2014年1月-2015年12月在本科行窝沟封闭的200例7-9岁儿童的463颗恒牙随机分为两组,对照组选用Eco-s封闭剂,实验组采用SDI Conseal封闭剂。随访6个月-2年,观察两组封闭剂保留和患龋情况。结果 术后6个月实验组和对照组窝沟封闭剂保留率比较,差异无统计学意义（P〉0.05）,术后1、2年实验组封闭剂保留率高于对照组,差异有统计学意义（P〈0.05）。术后1、2年,实验组患龋率均低于对照组（1.3%vs 2.6%,3.0%vs 4.3%）,差异有统计学意义（P〈0.05）。结论 SDI Conseal固化后封闭性较佳,优于Eco-s窝沟封闭剂。

Objective To compare the preventive effect of SDI Conseal and Eco-s pit and fissure sealant for caries in children.Methods 200 children （463 permanent teeth） aged 7 to 9 in the department from January 2014 to December 2015 were selected to perform sealant technique on their first molars and randomly divided into two groups,first molar in trial group wassealed with SDI Conseal sealant and in control group was sealed with Eco-s sealant.Sealant retention rate and caries prevalence were observed follow-up for 6 months to 2-years.Results At 6 months follow-up,there was no statistical difference in sealant retention rate between two groups （P〉O.05）,at 1 year and 2 years follow-up,the reten- tion rate in the trial group were significantly higher than those in the control group （P〈0.05）.However, caries prevalence in the trial group were significantly lower than those in the control group at 1 and 2 years follow-up （1.3% vs 2.6%, 3.0% vs 4.3%）,the difference was statistically significant （P〈0.OS）.Conclusion SDI Conseal sealant is superior to Eco-s sealant to prevent caries in children.
