摘　　要：目的探讨不同镍钛机动器械对牙髓炎根管治疗的效果。方法2017年3月至2018年3月口腔科行根管治疗的牙髓炎患者90例按镍钛预备系统的不同分为3组,每组30例。A组采用不锈钢K锉以逐步后退法预备根管,B组采用Protaper机用镍钛预备系统用冠根向法预备根管,C组采用Mtwo机用镍钛预备系统用同步技术预备根管,3组均使用冷侧压法充填根管。比较3组患者的单个根管预备时间、根管预备成形效果、根管充填效果、治疗后疼痛情况、器械折断率。结果A组单个根管预备时间明显长于B组及C组,差异有统计学意义(P<0.05),而B组与C组间差异无统计学意义(P>0.05);A组根管流畅度为61.70%明显低于B组93.75%、C组96.74%(P<0.05),而B组与C组间差异无统计学意义(P>0.05);A组根管欠充和根管超充例数明显多于B组和C组,而根管适充率较低(P<0.05),而B组与C组间差异无统计学意义(P>0.05);A组根管预备后疼痛率为20.00%明显高于B组6.67%、C组3.33%(P<0.05),而B组与C组间差异无统计学意义(P>0.05);3组间器械折断率差异无统计学意义(P>0.05)。结论Protaper和Mtwo机用镍钛预备系统进行根管治疗的效果更佳,根管预备时间短,根管预备成形效果好,根管适充率高,器械折断率低,具有积极的临床意义。Objective To investigate the therapeutic effects of different nickel-titanium mechanical instruments in treatment of pulpitis root canal. Methods A total of 90 cases with pulpitis who underwent root canal therapy in our hospital from March 2017 to March 2018 were divided into three groups accoding to the different nickel-titanium prepared system,with30 cases in each group. In group A,the root canals were prepared by backward method step by step with stainless steel K file,however in group B,the root canals were prepared by crown root orientation method through Protaper machine nickel-titanium system,and in group C the root canals were prepared by synchronization technology through Mtwo machine nickel-titanium prepared system. The root canals in three groups were filled by cold lateral compression. The single root canal preparation time,forming effect of root canal preparation,the filling effect of root canal,pain after treatment,equipment broken rate in the three groups were observed and compared. Results The single root canal preparation time was(14. 32 ± 0. 68) min in group A,which was significantly longer than that(5. 89 ± 0. 48) min in group B and(5. 11 ± 0. 54) min in group C(P <0. 05),however there was no significant difference in the single root canal preparation time between group B and group C(P> 0. 05). The fluency degree of root canal in group A was 61. 70%,which was significantly lower than that(93. 75%) in group B and that(96. 74%) in group C(P < 0. 05),however there was no significant difference in the fluency degree of root canal between group B and group C(P > 0. 05). The number of underfilling and overfilling of root canals in group A was significantly more than that in group B and group C,moreover,the appropriate filling rate of root canals in group A was more lower(P < 0. 05),however there were no statistically significant differences in the number of underfilling,overfilling,and appropriate filling rate of root canals between group B and group C(P > 0. 05). The pain rate after root canal pr
