摘要
目的 探讨机用ProTaper镍钛合金预备磨牙根管的临床效果.方法 选择2013年3月至2014年8月在我科要求进行磨牙根管治疗的120例牙髓炎或根尖炎患者,采用随机数字法分为试验组(用ProTaper 进行根管预备)和对照组(用不锈钢K锉进行根管预备),治疗后采用x2、f检验或秩和检验比较2组的预备时间、疼痛情况、预备和填充效果.结果 试验组的预备时间显著短于对照组(t=-16.273,P＜0.01);试验组发生1～4级疼痛的分布情况与对照组比较差异无统计学意义(U=2.018,P=0.107);试验组的预备优秀率(x2=6.508,P=0.011)和填充适充率(x2=6.815,P=0.033)均显著高于对照组.结论 使用机用ProTaper镍钛合金预备磨牙根管的效果好,并且安全、快速,值得临床推广.
Abstract
Objective To evaluate the quality of molar root canal preparation using ProTaper rotary instruments.Methods From March 2013 to August 2014,120 adult patients with myeloid or apical periodontitis diagnosed to receive root canal treatment were divided into two groups based on the randomly-paired principle.In the experimental group,root canals were prepared with ProTaper,and in the control group,root canals were prepared with stainless steel K file.After treatment,the preparation time,pain state,preparation and filling effect of the two groups were compared by chi square,t or rank sum test.Results Preparation time in the experimental group was significantly shorter than that in the control group (t =-16.273,P ＜0.001);the distribution of grade 1-4 pain in the experimental group compared with the control group is of no difference (U =2.018,P =0.107);the preparatory excellent rates (x2 =6.508,P =0.011) and fill the appropriate charge rate (x2 =6.815,P =0.033) of the experimental group were significantly higher than those in the control group.Conclusion Molar root canal preparation with rotary ProTaper files is convenient,effective,secure,and worthy of promotion.
