摘要 目的:对比ProTaper机用镍钛系统与不锈钢K锉在根管预备中的临床效果。方法:312例患者随机分成治疗组和对照组,治疗组156例,采用ProTaper机用镍钛器械冠根向深入法预备根管,对照组156例,采用常规ISO手用不锈钢根管锉以逐步深入技术预备根管。记录比较根管预备时间、术中根管断针发生率、根管恰填率、根充术后疼痛发生率。结果:治疗组和对照组在根管预备时间、术中根管断针发生率、根管恰填率、术后疼痛发生率均有统计学差异(P<0.01),治疗组根管预备时间(4.06±0.51)min明显少于对照组(6.11±0.56)min,治疗组根管恰填率(89.25%)明显高于对照组(78.12%),治疗组根充术后疼痛发生率(2.25%)明显低于对照组(9.05%);治疗组术中根管断针发生率(5.64%)明显高于对照组(1.52%)。结论:ProTaper机用镍钛器械预备根管具有良好的根管成形性能,根充效果好,操作简易。但术中根管断针发生率较手用不锈钢根管锉高。
