摘　　要：目的比较单尖法、冷牙胶侧方加压法、Beefill 2 in 1热牙胶充填3种方法的临床效果。方法 180例牙髓病、根尖周病患者随机分为A、B、C 3组,分别采用冷牙胶侧方加压、Beefill2 in 1热牙胶充填、单尖法根管充填。观察患牙根充的时间、术后疼痛情况、恰充率、牙根纵折发生率及根充成功率。结果 C组根充的时间为(62.6±7.2)s,短于其他两组(P<0.01);C组术后疼痛率为1.67%,低于其他两组(P<0.05);C组的恰充率为98.33%,高于其他两组(P<0.05);C组牙根纵折发生率低;C组的根充成功率为96.61%与其它两组比较无统计学差异(P>0.05)。结论单尖法根管充填疗效高、操作时间短、牙折发生率低、值得临床推广应用。Objective To compare the therapeutic efficacy of the matched-taper single cone obturation, warm gutta-percha Beefill 2 in 1 and the cold lateral condensation. Methods 180 patients were randomly divided into group A, B, C, each containing 60 patients （ 60 teeth） , and were treated with the cold lateral condensation, the warm gutta-percha Beefill 2 in 1 and the matched-taper single cone obturation, respectively. The obturation time, postoperative pain, filling fitness rate, incidence of vertical root fracture, and success rate of obturation were observed. Results The obturation time of group C was （62.6±7.2）s, shorter than that in the other two groups （ P〈0.01） . Occurrence rate of postoperative pain in group C was 1.67%, lower than that in the other two groups（ P〈0.05） . Filling fit-ness rate in group C was 98.33%, higher than that in the other two groups （ P〈0.05） . The incidence of vertical root fracture in group C was low. Success rate of obturation in group C （ 96. 61%） showed no significant difference compared with the other two groups （ P〉0.05） . Conclusion Given its high curative effect, short operation time, and low incidence of tooth fracture, matched taper single cone obturation is worthy of clinical application.
