摘要 目的:评价机用镍钛器械与传统手用不锈钢器械在乳牙根管治疗中的临床疗效。方法:符合根管治疗适应证的80颗乳磨牙随机分成A、B两组,每组40颗。A组以手用不锈钢器械行根管预备,B组为机用镍钛器械;根尖定位仪结合X线片法确定根管工作长度,Vitapex充填根管。根据治疗前后的X线片对根管的预备以及充填效果进行评价,并对两组的根管预备时间、患儿对治疗的疼痛反应、根管治疗后的远期疗效进行对比。结果:机用镍钛器械根管预备效果显著优于手用不锈钢器械,包括操作时间、预备后根管的锥度和流畅度、根管充填效果及远期疗效等指标,两组之间的差异有统计学意义(P<0.05)。两组患儿在根管预备过程中以及预备后均偶有疼痛等不适感,组间比较无统计学差异(P>0.05)。结论:机用镍钛器械在乳牙根管预备中可明显节省治疗时间、提高工作效率,并且预备后的根管锥度更有利于充填。
