摘　　要：目的探讨根管再治疗术中采用不同根管预备方法对患者术后疼痛的影响。方法将我院2013年7月-2016年7月收治的68例根管再治疗术患者随机分为两组,实验组34例,采用superpass(3s)联合冠向下预备法,和对照组34例,用牙胶去除后采用逐步后退法预备根管,连续观察3 d评价患者术后疼痛情况。结果实验组患者术后3 d内,1级疼痛率(70.6%)显著高于对照组(35.3%),实验组患者术后3 d疼痛情况明显优于对照组(P<0.05)。结论根管再治疗术中采用3s器械联合冠向下预备法可有效降低患者术后疼痛率,减轻患者疼痛,值得广泛推广应用。Objective To study the root canal treatment again in different root canal preparation method of the impact on the patients with postoperative pain. Methods 68 cases of root canal treatment were selected from July 2013 to July 2016 in our hospital, and they were randomly divided into two groups, the experimental group included 34 cases, used ProTaper nickel titanium system combined crown down preparation method, and the control group included 34 cases, the teeth were removed used stepwise regressive method to prepare the root canal, postoperative pain of patients with 3 d of two groups was evaluated. Results The patients of the experimental group with postoperative 3 d, level 1 pain rate （35.3%） was significantly lower than control group （70.6%）, 3 d postoperative pain of the experimental group was better than control group （P〈0.05）. Conclusion Root canal treatment of intraoperative again by ProTaper nickel titanium system combined crown down preparation method can effectively decrease the rate of patients with postoperative pain, relieve patients＇ pain, is worth popularization and application widely.
