| 目的：评价机用ProTaper 镍钛根管器械进行恒磨牙根管预备的临床疗效。方法：2007 年7 月至2010 年12 月期间就诊的需
进行根管治疗的109 患者，共计128 颗磨牙，包括牙髓炎54 颗牙，慢性根尖周炎74 颗牙。按随机配对原则分入实验组和对照组，
每组64 颗牙。实验组用机用ProTaper 镍钛根管锉预备根管，对照组用不锈钢K 型锉预备根管。两组均采用侧向加压法充填根管，
记录每颗患牙的单个根管预备所用时间、根管充填效果、术后不良反应及随访到的远期疗效。结果：机用ProTaper 镍钛器械预备
单根管所耗时间明显少于对照组，根管预备后疼痛发生率明显低于对照组，根管适充率实验组明显优于对照组，根管治疗术后1
年疗效比较也优于对照组。结论：使用机用ProTaper 器械进行恒磨牙根管预备快速有效，根充效果好，并发症发生率低，远期疗效
确切，值得临床推广。 |

| Objective: To evaluate the quality of molar root canal preparation using ProTaper rotary instruments. Methods: From
July 2007 to December 2010, 109 adult patients with 128 affected molars who were diagnosed to receive root canal treatment were divided
into two groups based on the randomly- paired principle. There were 64 teeth in each group. In group A, root canals were prepared
with rotary ProTaper files in crown-down mode，and in group B root canals were prepared with traditiona1 stainless stee1 K files by
hand. All root canals were obturated with lateral condensation method. The time consumed in preparation of each canal was recorded.
The outcome of root filling and side effects occurred after the operation were also noted. 1 year later all the cases were revisited and the
therapeutic results were verified. Results: Time consumed in the preparation of group A was significantly less than group B. Exact filling
rate of canals prepared with rotary ProTaper files was higher than with k files and side effects after the operation such as tooth ache and
swelling less occurred. One year post operational follow-up survey showed better therapeutic effects of root canal treatment in the group
using rotary ProTaper files. Conclusion: Compared with instrumentation with traditional stainless steel K files by hand, molar root canal
preparation with rotary ProTaper files is 1ess time consuming and more convenient. The occurrence of side effects was less and the outcome
of root filling was more satisfactory.
