目的：评价机用 ProTaper 镍钛根管器械行磨牙根管预备的临床疗效。方法2011年1月至2013年12月选取患有磨牙牙髓炎或根尖周炎的患者99例，共116颗磨牙；随机分为实验组（49例，58颗牙）和对照组（50例，58颗牙）。对照组用不锈钢 K 型锉预备根管，实验组用机用镍钛器 ProTaper 根管锉预备根管。充填根管过程两组患者均采用侧向加压法。根据 X 线片评价根管预备和充填效果，且记录每颗患牙的单个根管预备所用时间、术后不良反应及远期疗效。结果与对照组相比，机用 ProTaper 镍钛器械预备单根管所耗时间短，根管预备后疼痛发生率低，根管适充率高，根管治疗术后1年疗效好。结论使用机用 ProTaper 器械进行恒磨牙根管预备快速、高效，根充效果好，术后疼痛少，值得临床推广。

Objective To evaluate the quality of molar root canal preparation using ProTaper rotary instruments. Methods From January 2011 to December 2013,99 adult patients with 116 affected molars who were diagnosed to receive root canal treatment were divided into two groups based on the randomly - paired principle. There were 58 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 traditional stainless steel 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 af-ter 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 less time consuming and more convenient. The occurrence of side effects was less and the outcome of root filling was more satisfactory.
