摘　　要：目的:观察镍钛机动器械protaper和wave one在磨牙根管治疗术一次法中的近期疗效。方法:将90颗牙髓炎、无症状死髓牙随机分成3组,分别为P组(ProTaper机动根管预备,热牙胶即刻充填)、W组(Wave One机动根管预备,热牙胶即刻充填)、K组(K锉手动根管预备,冷牙胶即刻充填),评价3组一次性根管治疗术后反应、近期疗效。结果:90颗患牙经一次性根管预备后即刻充填,P组和W组术后1周内疼痛明显低于K组,3个月和6个月复诊观察成功率明显高于K组,根管预备耗时W组<P组<K组。结论:P组和W组的临床疗效明显优于K组,W组比P组平均耗时更短。镍钛机动器械具有省时高效的优点,并能减少术后反应,临床上值得推广应用。Objective：To observe the short-term effect of two nickel titanium motors,Protaper and Wave one,on onetime molar root canal therapy.Methods：Ninety teeth with pulpitis or asymptomatic nonvital teeth were randomly divided into 3groups：group P（ProTaper for root canal preparation and warm gutta percha for immediately filling）,W group（Wave one for root canal preparation and warm gutta percha for immediately filling）,and group K（K file for root canal preparation and cold gutta percha for immediately filling）.The curative effect and postoperative reaction of three groups were evaluated after one-time root canal treatment.Results：Ninety teeth was treated with one single root canal preparation and immediately filled.The pain of group P and group W within one week was significantly lower than that of group K.After 3months and 6months observation,the success rate of group P and group W was obviously higher than that of group K.The root canal preparation time was in the sequence of group Wgroup Pgroup K.Conclusion：The clinical efficacy of group P and group W was significantly better than that of group K,and the average preparation time of group W was shorter than that of group P.Nickel titanium motor has the advantages of saving time and high efficiency,and can reduce the postoperative reaction.
