    [摘要]目的：探讨自酸蚀与全酸蚀粘接剂修复穿髓型楔状缺损的疗效，为穿髓型楔状缺损的治疗提供参考。方法：选取2018年4月-2018年10月笔者科室就诊的穿髓型楔状缺损患者60例(68颗患牙)，将患者随机分为自酸蚀组30例(36颗患牙)与全酸蚀组30例(32颗患牙)，两组患者均进行开髓及完备的根管治疗，自酸蚀组采取Adper Easy One自酸蚀粘接剂+纤维桩+复合树脂修复，全酸蚀组采取Prime＆Bond NT全酸蚀粘接剂+纤维桩+复合树脂修复，观察治疗完成后6个月、12个月的疗效。结果：治疗后6个月，自酸蚀组治疗成功率为97.22%，全酸蚀组治疗成功率为93.75%，两组比较差异无统计学意义(P>0.05)；治疗后12个月，自酸蚀组治疗成功率为94.44%，全酸蚀组治疗成功率为75.00%，两组比较差异有统计学意义(P<0.05)。结论：自酸蚀与全酸蚀粘接剂修复穿髓型楔状缺损近期疗效相当，但随着时间延长全酸蚀粘接剂修复治疗效果有所下降，主要原因为继发龋。
