摘　　要：目的 分析比较超声冲洗技术与注射器冲洗技术对根管治疗失败再治疗的临床效果差异。方法 对60例患牙随机分为超声冲洗组和注射器冲洗组各30例,进行常规再治疗,观察1年以后的复查情况并评定治疗效果。结果 超声冲洗组的临床症状改善率、治疗瘘管有效率以及根尖阴影有效率分别为96.7%、100.0%、85.7%,对照组为76.7%、95.5%、78.6%,两组差异均有统计学意义(均P<0.05),两组患者恰充率分别为90.0%和86.7%,两组差异无统计学意义(P>0.05)。结论 在根管治疗失败行再治疗的过程中运用超声冲洗技术能够有效地提高疗效。Objective To evaluate the clinical efficacy of ultrasonic irrigation and syringe irrigation in re-treatment the failure in endodontic treatment. Methods Sixty teeth underwent re-treatment were divided into ultrasonic irrigation group（n=30） and syringe irrigation group（n=30）, X-ray and clinical performance were observed for one year. Results The effective rates in patients with clinical symptoms, in teeth with fistula and in teeth with periapical translucent radiogrphe of syringe irrigation were 96.7%, 100.0% and 85.7%, respectively in ultrasonic irrigation groupand 76.7%, 95.5% and 78.6% in the syringe irrigation group. There had significant difference in the efficacy promotion of clinical symptoms and periapical lesion between two groups, two groups of patients with appropriate charge rates were 90.0% and 86.7%, the difference was not statistically significant （P〉 0.05）. Conclusion Ultrasonic irrigation can promote the success rate in re-treatment the failure in endodontic treatment.
