摘　　要：背景:GC Fuji Ⅸ型玻璃离子水门汀作为楔状缺损的一种充填材料,在临床上越来越受关注,但其与临床常用的增强型玻璃离子水门汀修复楔状缺损效果的比较尚不清楚。目的:比较GC Fuji Ⅸ型玻璃离子水门汀和增强型玻璃离子水门汀两种材料修复老年人楔状缺损的临床疗效。方法:随机将80颗需做楔状缺损修复的患牙分成两组,分别用GC Fuji Ⅸ型玻璃离子水门汀(实验组)和增强型玻璃离子水门汀(对照组)充填,修复后即刻,修复后3,6个月和1年分别对修复体的色泽协调性、边缘密合度、修复体完整度、继发龋的发生以及牙髓症状5个方面进行临床效果评价。结果与结论:在修复后3,6个月及1年的临床评价中,实验组的色泽协调性优于对照组(P<0.05);在修复后的6个月以及1年的疗效观察中,实验组的边缘密合度明显优于对照组(P<0.05);在修复1年后的临床评价中,实验组的修复体完整度优于对照组(P<0.05)。说明GC Fuji Ⅸ型玻璃离子是一种充填老年人楔状缺损的理想材料,在1年内效果优于增强型玻璃离子水门汀。BACKGROUND：As a kind of filling material for wedge-shaped defects,GC Fuji IX glass-ionomer cement has arose more and more attention.However,the comparison of repair results between GC Fuji IX glass-ionomer cement and reinforced glass-ionomer cement are poorly understood.OBJECTIVE：To compare the clinical effect of GC Fuji IX glass-ionomer cement and reinforced glass-ionomer cement for repairing wedge-shaped defects of old people.METHODS：Totally 80 teeth were randomly divided into 2 groups,and filled by GC Fuji IX glass-ionomer cement（experimental group）and reinforced glass-ionomer cement（control group）,respectively.The clinical effect of 2 materials were evaluated on color match,edge density heterozygosity,restoration integrity,occurrence of secondary caries and pulp symptom at immediately,3 months,6 months and 1 year after placement.RESULTS AND CONCLUSION：The color match of the experimental group was better than that of the control group at 3 months,6 months and 1 year after placement（P 0.05）;and the edge density heterozygosity of the experimental group was superior to the control group at 6 months and 1 year after placement（P 0.05）;in addition,the restoration integrity of the experimental group was surpass the control group at 1 year after placement（P 0.05）.It demonstrated that GC Fuji IX glass-ionomer cement is an ideal choice for wedge-shaped defects of old people,which exhibits superior effects to reinforced glass-ionomer cement in 1-year follow-up.
