摘　　要：目的: 分析机用镍钛器械对乳牙牙髓病患儿的根管治疗术的影响,并总结临床经验。 方法: 在我院2017年5月至2019年5月收治的乳牙牙髓病患儿中选择100例进行对比实验,采用随机数字法简单随机分为对照组和试验组各50例,对照组患儿采用常规常规手用镍钛器械行根管预备,试验组患儿采用机用镍钛器械行根管预备。记录并分析两组患儿的根管预备操作时间、预备效果良好率及并发症情况。 结果: 对照组患儿根管预备操作时间(62.1±6.27,s)明显高于试验组(45.18±4.29,s),存在统计学差异(t=15.748,P<0.001);对照组预备效果良好患儿例数(38例)明显低于试验组(49例),对照组总预备效果良好率(76%)低于对照组(98%)(χ 2=10.698,P<0.001);对照组患儿根管阻塞(3例,6%)、侧移(1例,2%)及变形(1例,2%)症状均有发生,试验组患儿出现1例术后根管阻塞现象,并发症总发生率(10%)稍低于对照组(2%)(χ 2=2.837,P=0.092)。 结论: 在乳牙牙髓病患儿的根管治疗术中,采用机用镍钛器械行根管预备可大大缩减根管预备操作时间,提高预备效果,一定程度上提高术后恢复情况,值得在相关临床治疗中推广。Objective: To analyze the effect of nitinol instrument on endodontic treatment of children with pulpopathy of primary teeth, and summarize the clinical experience. Methods: From May 2017 to May 2019, 100 children with primary dental pulp disease in our hospital were selected for comparative experiment, and randomly divided into control group and test group with 50 cases each by random number method. Children in the control group were prepared with conventional hand nitinol instruments, while children in the test group were prepared with mechanical nitinol instruments. The time of root canal preparation, the rate of good preparation effect and complications were recorded and analyzed. Results: The operation time of root canal preparation (62.1, 6.27, s) in the control group was significantly higher than that of the test group (45.18, 4.29, s), and there was a statistical difference (χ 2=10.698,P<0.001), and the number of children with good preparation effect in the control group (38 cases) was significantly lower than that of the test group (49 cases). In the control group, the good rate (76%) was lower than that of the control group (98%)(χ 2=10.698,P<0.001), and the root canal obstruction (3,6%), lateral shift (1,2%) and the deformation (1,2%) of the children in the control group were all occurred. The overall incidence of complications (10%) was slightly lower Control (2%)(χ 2=2.837,P=0.092). Conclusion: In the root canal treatment of children with pulpopathy of deciduous teeth, the use of mechanical nitinol instruments for root canal preparation can greatly reduce the operation time of root canal preparation, improve the preparation effect. For a certain extent, it can improve the postoperative recovery, which is worth promoting in the relevant clinical treatment.
