摘　　要：目的:评价ProTaper手用镍钛锉行一次法或两次法磨牙直根管治疗的临床效果和可靠性。方法:选择患有牙髓炎磨牙直根管患牙184例,采用ProTaper手用镍钛锉逐步深入技术预备根管后,随机分为2组:一次法根管治疗组行牙胶尖加碧兰根管糊剂侧方加压技术充填根管,2次法根管治疗组根管内封入樟脑酚棉球,待无症状后再行根充,比较2组治疗后1、7、30d患者疼痛反应情况。结果:184例中有159例获得完整随访资料,其中一次法根管治疗组为82例,2次法根管治疗组为77例。一次法、两次法根管治疗组术后1d中/重度疼痛的发生率分别为9.76%和7.79%,之后逐渐下降,但2组间1、7、30d的疼痛发生率差异均无统计学意义(P>0.05)。结论:严格掌握好适应证,一次法根管治疗术较两次法可减少复诊次数,疼痛无明显差异,值得推广。Objective： To determine the postoperative pain of 1- or 2-visit root canal treatment （RCT） with ProTaper for hand-use in the molors. Methods： In 184 patients with pulpitis root canal was prepared with hand-use ProTaper using crown-down technique, then were randomly divided into two groups： 1-visit RCT and 2-visit RCT group. The teeth in 1-visit group were at the first appointment obturated by means of cold lateral condensation and those in the 2-visit group before obturated were medicated with camphor carbol one week. 1 d, 7 d and 30 d after the initial appointment, asked about the occurrence of postoperative pain. The level of discomfort was rated as no pain, mild pain, moderate pain, or severe pain （flare-ups）. Dated were statistically analyzed. Results： 159 patients of 184 completed follow-up： 82 in 1-visit RCT and 77 in 2-visit RCT. The rate of moderate pain or severe pain is 9.76% and 7.79% at postoperative 1 d of 1-visit group and 2-visit group, then gradualy declined, but the pain occurrence happened no difference between two groups at 1, 7 and 30 d （P 〈0.05）. Conclusions： If chosen proper patients, 1-visit RCT is worth of popularize for only one visit and the postoperative pain has no difference.
