摘　　要：目的探讨机用Pro Taper镍钛锉与不锈钢K锉手扩法在磨牙根管治疗中的临床疗效。方法选取2017年1~12月我院进行磨牙根管治疗的患者共112例,患牙120颗。按照患者就诊顺序随机分为镍钛锉组(56例,患牙61颗)与不锈钢组(56例,患牙59颗),分别使用机用Pro Taper镍钛锉与不锈钢K锉手扩法治疗,比较两组患者的根管治疗效果。结果镍钛锉组患者的根管预备时间、根管填充时间均明显低于不锈钢组,且镍钛锉组患者的根管预备形态良好率明显高于不锈钢组,差异均有统计学意义(P<0.05)。镍钛锉组患者的器械分离率低于不锈钢组,且镍钛锉组患者的恰填充率明显高于不锈钢组,差异均有统计学意义(P<0.05)。两组患者的根管术后1、3 h的疼痛率比较,差异均无统计学意义(P>0.05);镍钛锉组患者术后24、72 h的疼痛率分别明显低于不锈钢组,差异均有统计学意义(P<0.05)。结论机用Pro Taper镍钛锉在磨牙根管治疗中具有较好的临床效果,缩短了根管预备及填充时间,能提高根管预备形态的良好率及恰填充率,降低术后疼痛的发生率,安全可靠,值得临床推荐使用。Objective To investigate the clinical effect of the machine-made Pro Taper nickel-titanium file and stainless steel k file in the root canal treatment of molars. Methods A total of 112 patients with 120 teeth were selected from January to December 2017 for root canal treatment of molars in our hospital. The patients were randomly divided into nickel-titanium file group（56 cases, 61 teeth） and stainless steel group（56 cases, 59 teeth） according to the order of their visit. They were treated with Pro Taper nickel-titanium file and stainless steel k file respectively. The root canal treatment effects of the two groups were compared. Results The root canal preparation time and filling time of nickeltitanium file group were significantly lower than those of stainless steel group, and the good rate of root canal preparation shape of nickel-titanium file group was significantly higher than that of stainless steel group, the differences were statistically significant（P〈0.05）. The separation rate of the nickel-titanium file group was lower than that of the stainless steel group, and the filling rate of the nickel-titanium file group was obviously higher than that of the stainless steel group, the differences were statistically significant（P〈0.05）. There was no statistically significant difference in the pain rate between the two groups at 1, 3 h after root canal surgery（P〈0.05）. The pain rates at 24, 72 h after operation in the nickel-titanium file group were significantly lower than those in the stainless steel group, the differences were statistically significant（P〈0.05）. Conclusion The machine-made Pro Taper nickel-titanium file has good clinical effect in molar root canal treatment, shortens root canal preparation and filling time, can improve the good rate and just filling rate of root canal preparation shape, reduces the incidence of postoperative pain, is safe and reliable, and is worthy of clinical recommendation.
