摘　　要：目的探析Waveone Gold、Protaper、MTwo及Reciproc 4种不同镍钛器械在磨牙弯曲根管中的应用效果。方法收集100颗弯曲离体磨牙,采用随机数字表法分为五组,分别使用Waveone Gold、Protaper、Reciproc、MTwo和不锈钢K锉进行根管预备。比较五组根管预备效果及相关并发症、根管偏移量、根管充填效果。结果五组根管预备时间比较,差异有统计学意义(P<0.05),以Waveone Gold组根管预备时间最短;五组台阶形成发生率比较,差异有统计学意义(P<0.05),五组根管侧穿、器械折断发生率比较,差异无统计学意义(P>0.05)。五组2mm、4mm及6mm垂直平面根管偏移量较小,差异有统计学意义(P<0.05),以Waveone Gold组根管偏移量最小。五组超充率比较,差异无统计学意义(P>0.05)。五组恰充及欠充率比较,差异有统计学意义(P<0.05),其中Waveone Gold组、Reciproc组恰充率均高于对照组,欠充率均低于对照组(P<0.05)。结论磨牙弯曲根管应用镍钛器械可缩短根管预备时间,相关并发症少、根管偏移量小、根管充填效果佳,尤以Waveone Gold具有明显优势。Objective To investigate the application effects of Waveone Gold,Protaper,MTwo and Reciproc on curved root canals of molar teeth.Methods Collect 100 curved in vitro molars and randomly divide them into 5 groups,Root canal preparation was performed using Waveone Gold,Proteper,Reciproc,MTwo,and stainless steel K-files,respectively.Compare the root canal preparation effects and related complications,root canal offset,and root canal filling effects among five groups.Results After analysis,the five groups of root canal preparation time,the difference was statistically significant,Waveone Gold group the shortest preparation time(P<0.05).There were statistically significant differences in the incidence of step formation among the five groups(P<0.05),but there were no statistically significant differences in the incidence of lateral root canal puncture and instrument fracture among the five groups(P>0.05).The root canal offset of 2mm,4mm and 6mm vertical plane in the five groups was small,the difference was statistically significant,and the root canal offset of Waveone Gold group was the smallest(P<0.05).There was no statistically significant difference in overcharging rates among the five groups(P>0.05).However,there was a statistically significant difference in overcharging and underfilling rates among the five groups(P<0.05),with Waveone Gold and Reciproc groups having higher overcharging rates than the control group and lower underfilling rates than the control group(P<0.05).Conclusion The application of Ni-Ti instruments in curved molar root canals can shorten the preparation time of root canals,reduce the related complications,reduce the deviation of root canals,better root canal filling effect,especially Waveone Gold have obvious advantages.
