摘　　要：目的对超声冲洗与镍钛机动器械联合应用于慢性根尖周炎一次性根管治疗的临床疗效进行评价。方法对77例患者81颗牙按就诊顺序随机分为实验组和对照组。2组均采用镍钛根管预备后,实验组:43颗患牙进行超声根管冲洗,一次法完成根管充填治疗。对照组:38颗患牙进行注射器冲洗,一次法完成根管充填治疗。冲洗液均为0.9%生理盐水。观察根管充填1周后的术后疼痛反应及1年后的根管充填疗效。结果 1周后复诊2组术后疼痛反应有显著性差异(P<0.05)。术后1年复诊,2组疗效无明显差异(P>0.05)。结论超声冲洗与镍钛器械联合应用,对于治疗慢性根尖周炎一次法完成根管充填,可减少患者复诊次数,缩短疗程,同时提高根管充填质量,值得临床推广使用。Objective To use pairs of ultrasonic cleaning combined with the nickel-titanium rotary instruments in a method of chronic periapical root canal therapy in the clinical efficacy evaluation. Methods According to treatment ,81 teeth were randomly divided into experimental and control groups. Two groups were using nickel-titanium root canal preparation. Experimental group： 43 teeth for ultra- sonic root canal irrigation. Control group： 38 teeth for rinse syringes. Washing fluid was normal saline. The root canal filling was observed after a week and one year of postoperative pain response Results A week later, two groups of post-operative pain showed there was significant difference in responses （ P 〈 0.05 ）. One year later, the two groups showed no significant difference in efficacy （ P 〉 0.05 ）. Conclusions The combination of nickel-titanium instruments and ultrasonic irrigation, for the treatment of chronic periapieal, was a method to complete the root canal filling, could reduce both the number of patients＇ subsquent visits and the postoperative pain response, while it could improve the quality of root canal filling.
