摘　　要：目的:比较三种玻璃离子水门汀牙体充填修复后边缘封闭性的差别。方法:离体前磨牙80颗按要求制备洞型,随机分成4组,分别用三种玻璃离子水门汀(新世纪齿科材料有限公司玻璃离子水门汀I型、II型,日本GCFujiII)充填修复,另外一组用玻璃离子水门汀II型修复后再涂隔湿剂(凡士林)。经冷热交替试验(0℃～55℃,循环500次),采用1%亚甲蓝染料渗入法观察充填体与牙体洞壁间边缘微渗漏的情况。结果:玻璃离子水门汀I型(普通型)边缘封闭性与其他各组存在显著差异(P<0.01);玻璃离子水门汀II型(树脂增强型)、GCFujiII与隔湿剂组边缘封闭性存在差异(P<0.05);玻璃离子水门汀II型与GCFujiII边缘封闭性比较不存在差异(P>0.05)。结论:玻璃离子水门汀II型与GCFujiII边缘封闭效果相同;隔湿剂能降低微渗漏。Objective：A comparison of marginal seal of three glass ionomer cement after repairing.Method：80 premolars in vitro preparation of the required cavity,were randomly divided into 4 experimental groups of 20 teeth each.Three kinds of glass ionomer cement were repaired in three different groups,Another group was repaired by type II glass ionomer cement and painted waterproof agent（vaseline）.After thermal cycling（0～55 ℃,×500）,the teeth were immersed in 1 % methylene blue dye,and observed micro-leakage.Result：Significantly differents were found type I glass ionomer cement group with the other groups（P 0.01）.Significantly differences were found the waterproof agent group with type II glass ionomer cement group and GCFuji II group（P 0.05）.No differences were found between type II glass ionomer cement group and GCFuji II group（P 0.05）.Conclusion：Marginal seal of type II glass ionomer cement and GCFuji II is the same.The waterproof agent can reduce the micro-leakage.
