3M Filtek Z350流动树脂与Pekaseal光固化窝沟封闭剂预防儿童龋病的临床效果研究

目的对比观察3M Filtek Z350流动复合树脂与Pekaseal光固化窝沟封闭剂预防儿童恒磨牙龋病的临床效果。方法对2009年1月至2011年6月间本院门诊符合纳入标准的126名6～10岁儿童的315颗恒磨牙随机分为两组,观察组选择3M Filtek Z350流动复合树脂进行窝沟封闭治疗(病例数=63,牙数=136),对照组采用Pekaseal光固化窝沟封闭剂进行窝沟封闭治疗(病例数=63,牙数=179),随访6个月~1年,复查封闭剂保留情况和患龋情况。结果术后6个月观察组和对照组窝沟封闭剂保留率无统计学差异(P>0.05),术后1年观察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6个月、1年,观察组患龋率均低于对照组,差异均有统计学意义(P<0.05)。结论采用3M Filtek Z350流动复合树脂进行窝沟封闭预防儿童恒磨牙窝沟龋效果显著,使龋病发生率大大降低,优于传统的窝沟封闭剂,值得临床推广应用。

Comparison of Preventive Effect of 3M Filtek Z350 Flowable Resin and Pekaseal Light-Cured Sealant for Caries in Children

Objective To compare the preventive effect of 3M Filtek Z350 flowable resin and Pekaseal light-cured pit and fissure sealant for caries in children.Methods One hundred and twenty six children aged 6 to 10 years were selected to perform sealant technique on their first permanent molars.First molars in trial group were sealed with 3M Filtek Z350 flowable resin and in control group were sealed with Pekaseal light-cured sealant.Sealant retention rate and caries prevalence were observed during 1-year follow up.Rusults At 6-month follow up,there were no statistical difference in sealant retention rate between the two groups（P0.05）.At 1 year follow up,the retention rate of flowable resin group was significantly higher than that of light-cured sealant group（P0.05）.However,caries prevalence of flowable resin group was significantly lower than that of light-cured sealant group at both 6-month and 1-year follow up（P0.05）.Conclusion 3M Filtek Z350 flowable resin is superior to pekaseal light-cured pit and fissure sealant to prevent caries in children.
