摘　　要：目的:研究不同冲洗方式对两种根管内常用消毒药物的清除效果。方法:将90颗单根管前磨牙去除冠部,形成13 mm标准根长,在根尖部建立标准人工沟,分别放置三联抗生素糊剂和氢氧化钙制剂,封药2周。使用常规针筒冲洗、声波根管冲洗器和超声治疗仪,配合10 mL 1%NaOCl溶液进行根管冲洗。经体视显微镜放大后对人工沟内药物残余量进行评分,统计分析各组的冲洗效果。结果:三种冲洗方式均未能完全去除根管内的消毒药物。声波冲洗器和超声治疗仪对三联抗生素糊剂的清除效果无明显区别(P>0.05),但均显著优于针筒冲洗(P<0.01);超声冲洗对氢氧化钙制剂的冲洗效果明显优于针筒冲洗(P<0.01),声波冲洗器对氢氧化钙制剂的冲洗效果与其他两种方式无明显区别(P>0.05);同种冲洗方式对两种不同药物的冲洗效果间无统计学差异(P>0.05)。结论:所有冲洗方式均不能完全去除根管内的消毒药物,使用声波根管冲洗器和超声治疗仪可提高清除根管消毒药物的效果。Objective:To compare the efficacy of different irrigation techniques on the removal of intracanal medicaments.Methods:90 extrated single-rooted premolars were decoronated to obtain a standardized root length of 13 mm.The roots were split longitudinally into two halves and an artificial groove was prepared in the apical part of one segment.The triple antibiotic paste and calcium hydroxide were placed into the grooves.Two weeks later,the root canals were then irrigated with 10 mL of 1%NaOCl by three irrigation techiniques(conventional syringe irrigation,Vibringe sonic irrigation and passive ultrasonic irrigation).The amounts of intrcanal medicaments remaining in the grooves were scored with a stereomicroscope,and the data were evaluated statistically.Results:The intracanal medicaments could not be completely removed by these irrigation techiniques.Vibringe sonic irrigation and passive ultrasonic irrigation with 1%NaOCl removed significantly more triple antibiotic paste than the syringe irrigation(P<0.01),and there were no significant differences between the Vibringe sonic irrigation andpassive ultrasonic irrigation(P>0.05).The syringe irrigation was associated with significantly more remaining calcium hydroxide than passive ultrasonic irrigation(P<0.01).There were no significant differences between Vibringe sonic irrigation and the other two methods on removing the calcium hydroxide(P>0.05).The groups of two medicaments with the same irrigation technique did not have significant differences.Conclusions:All the irrigation techniques cannot completely remove the intracanal medicaments.The use of Vibringe sonic root canal irrigator and ultrasonic system may improve the efficacy of irrigation on the removal of intracanal medicaments.
