摘　　要：目的 比较Protaper机用镍钛锉与Orodeka Plex-v镍钛锉在磨牙根管预备中的效果。方法 选取在本院进行根管治疗的74颗上下颌第一磨牙,按就诊顺序分为P组(131个根管)与O组(138个根管),分别采用Protaper机用镍钛锉与Orodeka Plex-v镍钛锉进行根管预备,比较2组的根管治疗效果。结果 P组单根根管预备时间为(5.09±0.67) min,显著长于O组的(3.10±0.43) min ( P <0.05)。P组发生4支器械分离,台阶形成1例,根尖阻塞1例,无根管偏移;O组无器械分离、根管偏移、台阶形成、根尖阻塞发生, 2组差异有统计学意义( P <0.05)。2组根管充填恰填率比较,差异无统计学意义( P > 0.05)。结论 Protaper机用镍钛锉与Orodeka Plex-v镍钛锉均能达到良好的根管预备效果,但Orodeka Plex-v镍钛锉用时更短,安全性更高。Objective To compare the effect of Protaper nickel-titanium file and Orodeka Plex-v nickel-titanium file on the preparation of root canal of molars. Methods A total of 74 maxillary and mandibular molars for root canal preparation were collected and divided into group P with 131 canals and group O with 138 canals according to visiting order, and they were treated with Protaper and Orodeka Plex-v nickel-titanium files respectively. The effects of root canal treatment were compared between the two groups. Results The preparation time for single root canal in group P was (5.09±0.67) min, which was significantly longer than (3.10±0.43) min in group O ( P < 0.05). No instrument separation, transportation, apical blockage and ledge were observed in group O, whereas instrument separations occurred in 1 instrument, apical blockage in one case, ledge in one case and no transportation were observed in group P, and there were significant differences in above complications between two groups ( P <0.05). There was no significant difference in the ratio of adequate filling of root canal between two groups ( P >0.05). Conclusion Both Protaper and Orodeka Plex-v nickel-titanium files can achievea high performance in the root canal preparation of molars, but Orodeka Plex-v nickel-titanium file is more shorter in time of use and higher in security.
