摘　　要：目的观察ProTaper机用镍钛器械系统进行根管预备的临床疗效。方法选取患牙髓炎或根尖周炎的磨牙75例(75颗,214个根管),随机分为试验组和对照组。试验组采取ProTaper机用镍钛器械冠向下技术预备根管,对照组采用手用不锈钢K型锉逐步后退技术进行根管预备。比较两组根管预备所需时间及术后并发症出现情况。结果试验组根管预备的时间明显短于对照组,试验组根管预备的术后不适反应少于对照组。结论 ProTaper机用镍钛器械冠向下技术预备根管速度快,术后根尖疼痛反应小,根管成型锥度好,值得临床推广,但要注意预防器械折断。Objective To observe the clinical curative effect of ProTaper nickel-titanium rotary instrument＇ s system in root canal prepa- ration. Methods 75 persons（73 molars, 214 root canals） with pulpitis or periapical periodontitis were randomly divided into experimental group and control group. The test group used ProTaper nickel-titanium rotary instrument＇ s system in root canal preparation with downward technology, while control group used hand stainless steel K file with step-back technique in root canal preparation. Root canal preparation time required and the postoperative complications were compared between the two groups. Results The experimental group was significantly shorter than the control group in time spent, and less in postoperative complications. Conclusion ProTaper nickel-titanium rotary instrument＇ s system is faster and more comfortable, but attention should be paid to prevention of instrument fracture.
