摘要
目的比较光固化流体树脂与光固化窝沟封闭剂在儿童新生恒牙窝沟封闭预防龋坏的临床效果。方法临床选取150名7~10岁,双侧下颌第一恒磨牙无龋坏的儿童。每个儿童随机选取一侧作为试验组,用光固化流体树脂进行窝沟封闭,另一侧为对照组,用传统光固化窝沟封闭剂进行封闭。封闭治疗后6、12、24个月复查,检查封闭剂在牙面的保留率及龋病发生率,并进行统计学分析。结果 2年后试验组光固化流体树脂脱落率和龋病发生率分别为7.80%和2.13%,对照组传统窝沟封闭剂的脱落率和龋病发生率分别为21.43%和7.09%,两组封闭剂脱落率和龋病发生率均有显著性差异（P〈0.05）。结论光固化流体树脂在窝沟封闭预防龋坏治疗效果确切,值得临床推广。
Objective To compare the clinical effect of light-cured flowable resin and traditional light-cured pit and fissure sealant in preventing pit and fissure caries. Methods 150 children aged from 7 to 10 years with healthy permanent mandibular first molars were enrolled in this study. One side of permanent mandibular first molar was selected randomly as experimental group, which was sealed with light-cured flowable resin. The other side, as control group, was treated with traditional light-cured pit and fissure sealant. Pa- tients were followed up 6, 12 and 24 months later. The rate of resin loss and incidence of dental caries between two groups were com- pared by X2 test. Results After two years, the rate of sealant loss and the incidence of caries of experimental group （ 7.80% ; 2.13% ） were significantly lower than those of the control group（21.43% ; 7.09% ） （ P〈0.05 ）. Conclusions Light-cured flowable resin is an effectively anticarious and reliable pit and fissure sealant.
