摘要 目的:评价3种不同根管预备系统对弯曲根管预备的效果,为其临床应用提供依据。方法:选择需要进行下颌磨牙根管治疗患者60例,共60颗下颌磨牙,随机分为手动不锈钢K锉组、Mtwo机用Ni-Ti器械组和Protaper机用Ni-Ti器械组,每组20颗牙,分别采用传统的手动不锈钢K锉、Mtwo机用Ni-Ti旋转系统和Protaper机用Ni-Ti旋转系统进行根管预备,对3种器械预备根管的时间和根管预备效果进行比较分析。结果:Mtwo和Protaper机用Ni-Ti器械组的并发症发生率明显低于手动不锈钢K锉组(P<0.01),根管预备平均操作时间明显少于手动不锈钢K锉组(P<0.01),而Mtwo与Protaper机用Ni-Ti器械组间比较差异无统计学意义(P>0.05)。3组间的根管充填效果比较差异无统计学意义(P>0.05)。结论:Mtwo和Protaper机用Ni-Ti旋转系统对根管的预备效果优于手动不锈钢K锉组。
