摘　　要：目的:研究M3乳牙镍钛锉在乳牙根管治疗中的临床效果。方法:应用2种不同预备器械对3~8岁80名儿童患者共80颗慢性牙髓炎的乳牙进行根管治疗术,采用病例对照法,实验组和对照组各40名,实验组使用M3乳牙乳牙镍钛锉行根管预备,对照组使用不锈钢K锉行根管预备。分别记录两组根管预备操作时间、术后疼痛程度和术后X线片充填效果。结果:两组操作时间以及术后第1、3天疼痛度差异具有统计学意义(P<0.05),但术后X线充填效果以及术后第7天疼痛度无统计学差异(P>0.05)。实验组所需要的操作时间更短,术后第1、3天的疼痛程度更低。结论:运用M3乳牙镍钛锉进行根管预备能缩短根管治疗时间和降低术后患者的疼痛程度,M3乳牙镍钛锉值得在儿童患者临床治疗中推广。Objective:To study the clinical effect of M3 nickel-titanium ( NiTi) for primary teeth in root canal therapy in children.Methods:80 teeth with chronic pulpitis in 80 patients aged 3-8 years were divided into two groups by case-control design:M3 rotary nickel-titanium group and stainless steel K files group with 40 cases in each group.The operation time,postoperative pain degree,and postoperative X-ray were recorded,respectively.Results:There was no difference in postoperative X-ray evaluation and the pain degree in day 7 between two groups( P >0.05).The differences of the operation time and the pain degree at day 1 and day 3 were statistically significant ( P <0.05).The experimental group needed shorter operation time and the level of pain at day 1 and day 3 was lower.Conclusion:M3 nickel-titanium (NiTi) for primary teeth should be promoted because it can shorten the root canal treatment time and reduce the degree of postoperative pain of patients.
