摘　　要：目的观察不同根管再治疗器械与氯仿联合使用去除根管充填材料效果。方法选取2019年10月~2020年10月我院治疗的96例(96颗)患者为研究对象,按照随机数字表法将患者分为手用器械组、手用器械+氯仿组、R-endo组、R-endo+氯仿组、Mtwo R组、Mtwo R+氯仿组,各组16例,分别用手用器械和R-endo、Mtwo R机用镍钛再治疗锉并在不使用氯仿和联合氯仿情况下取出根管内充填材料,比较各组预备完成时间、到达工作长度所用时间、根尖孔碎屑量、根管壁残留充填物计分。结果Mtwo R组预备完成时间、到达工作长度所用时间均短于手用器械和R-endo组,R-endo+氯仿组预备完成时间、到达工作长度所用时间均短于手用器械+氯仿和Mtwo R+氯仿(P<0.05);手用器械+氯仿组到达工作长度所用时间短于手用器械(P<0.05),预备完成时间与手用器械组比较,差异无统计学意义(P>0.05);R-endo+氯仿组及Mtwo R+氯仿组预备完成时间、到达工作长度所用时间均短于R-endo组、Mtwo R组(P<0.05)。R-endo组+氯仿组、Mtwo R组+氯仿组推出根尖孔碎屑量均少于R-endo+氯仿组、Mtwo R+氯仿组(P<0.05),手用器械+氯仿组推出根尖孔碎屑量大于手用器械组(P<0.05)。各组根管壁清洁度比较,差异无统计学意义(P>0.05)。结论不同根管再治疗器械与氯仿联合使用可提高去除根管充填材料工作效率,缩短工作时间,减少根尖孔碎屑量,但对高根管壁清洁度无影响,有待临床进一步深入研究。Objective To observe the effect of using different root canal retreatment instruments in combination with chloroform to remove root canal filling materials.Methods A total of 96 patients(96 teeth)treated in our hospital from October 2019 to October 2020 were selected as the research objects.According to the random number table method,the patients were divided into the hand instrument group,the hand instrument+chloroform group,the R-endo group,the R-endo+chloroform group,the Mtwo R group,and the Mtwo R+chloroform group,with 16 cases in each group.Respectively use hand instruments and R-endo and Mtwo R nickel-titanium retreatment files,and remove the root canal filling materials without using chloroform and combined chloroform.Comparing the preparation completion time of each group,the time taken to reach the working length,the amount of apical foramen debris,and the scoring of the residual fillings on the root canal wall.Results The preparation completion time and the time to reach the working length of the Mtwo R group were shorter than those of hand equipment and R-endo group.The preparation completion time and the time to reach the working length in the R-endo+chloroform group were shorter than hand instruments+chloroform and Mtwo R+chloroform(P<0.05);The time it took for the hand equipment+chloroform group to reach the working length was shorter than that of the hand equipment(P<0.05),There was no statistically significant difference between the preparation completion time and the hand equipment group(P>0.05);R-endo+chloroform group and Mtwo R+chloroform group preparation completion time and time to reach the working length were shorter than R-endo group and Mtwo R group(P<0.05).The amount of apical foramen debris in the R-endo group+chloroform group,Mtwo R group+chloroform group was less than that of the R-endo+chloroform group and Mtwo R+chloroform group(P<0.05).The amount of debris in the apical foramen of the hand instrument+chloroform group was greater than that of the hand instrument group(P<0.05).There
