摘要:
摘 要： 目的 探讨冰硼液冲洗对离体牙根管内粪肠球菌感染的临床疗效。方法 收集根尖完整、发育良好的单根管前磨牙，经高温高压灭菌后，根管内接种粪肠球菌厌氧培养4 w建立粪肠球菌感染根管模型，之后随机分为3组（空白组：生理盐水+超声荡洗；阳性对照组：1%NaClO+超声荡洗；治疗组：冰硼溶液+超声荡洗）。在根管预备冲洗前、后分别取样根管内和根尖4 mm不同牙本质深度内细菌计数，进行统计学分析。结果 根管表面和根尖4 mm不同牙本质深度的粪肠球菌数，在根管冲洗前三组均显著差异（P>0.05）；根管冲洗后，阳性对照组和治疗组细菌计数结果均明显低于空白组，存在显著差异（P<0.05）。结论 冰硼液可以有效清除感染根管表面和根尖4 mm不同牙本质深度的粪肠球菌，疗效可靠。
