摘　　要：目的比较光固化树脂与玻璃离子封闭剂对第一恒磨牙的防龋效果。方法选择7-9岁儿童160名,口腔内第一恒磨牙无龋。每名儿童一侧的恒磨牙用常规光固化窝沟封闭,另一侧用玻璃离子封闭剂封闭窝沟,随访1年,观察两种材料在牙面上的保留情况和患龋率。结果封闭后部分和完全脱落率均随封闭时间延长而增加,封闭1年和6月完全脱落率和完整保存率差异有统计学意义(P<0.05)。光固化树脂窝沟封闭的完整保存率较玻璃离子略高,但在两种方法间进行比较差异无统计学意义(P>0.05)。两组儿童磨牙窝沟封闭后,6个月时检查患龋率,光固化树脂组(320颗)和玻璃组(320颗)患龋率分别为1(0.31%)和2(0.63%);1年时分别为12(3.75%)和14(4.38%)。两种方法预防龋齿效果差异无统计学意义(P>0.05)。结论两种窝沟封闭均能有效防龋,光固化树脂适宜在条件较好的牙科诊所进行,玻璃离子适用于大面积提供口腔保健,对于缺乏投资设备的地区,能用较少投入和较短时间达到龋病预防目的。Objective To compare the caries prevention effect of resin and glass ionomer cement sealant on first permanent molar teeth. Methods Totally 160 children aged between ？ and 9 years who had four erupted first permanent molar teeth were selected, one lateral first permanent molar teeth were sealed by resin sealant, the other lateral teeth were sealed by glass ionomer sealant. Then the sealant retention rate and the caries rate were observed for 1 year. Results The retention rate of glass ionomer sealant was relatively lower than that of resin sealant, but the caries prevention effect of the two methods was similar （P 〉 0.05）. The caries rates of the two methods were similar too （P 〉 0.05）. Conclusions The two methods are both effective for caries prevention, but resin sealant is more suitable for applying in dental clinics, and special glass ionomer sealant is suitable in large- scale oral health care for children.
