摘　　要：目的评价ProTaper镍钛锉预备磨牙根管的临床效果。方法选取96颗患有牙髓炎的磨牙,随机分为两组,分别使用ProTaper镍钛锉和不锈钢K锉预备根管,使用侧压法充填根管,记录器械分离数和术后疼痛例数,根据X线片评价根管预备效果。结果两组器械预备根管后,ProTaper组根管形态良好率为91.9%,不锈钢K锉组为51.1%,两者差异有统计学意义。ProTaper组术后疼痛反应的比例明显低于不锈钢K锉组(P<0.05)。两组器械分离数的差异无统计学意义。结论 ProTaper预备磨牙根管的成形效果好,术后疼痛反应少。Objective To evaluate the clinical effect of ProTaper in preparation of molars′root canals.Methods 96 molars were randomly divided into two groups and prepared by ProTaper and stainless steel K files.All canals were obturated with lateral condensation method.The incidence of instrument seperation and post-operative pain were recorded.The efficiency of preparation was analyzed with radiograph.Results In ProTaper group,91.9% of the canals were achieved continuous funnel shapes after preparation,while 51.1% of the canals were achieved in stainless steel K files group.The difference between two groups was statistically significant.There was more post-operative pain in the stainless steel K files group than in the ProTaper group（P0.05）.There was no statistically significance of instrument seperation between two groups.Conclusion ProTaper performed good shaping ability in molars′ root canals and generated less post-operative pain.
