目的:评估手用ProTaper根管扩大系统联合镍钛K锉对老年人磨牙根管治疗的效果。方法:110例118个慢性根尖周炎磨牙随机分为两组,实验组60个患牙,采用手用ProTaper根管扩大系统和镍钛K锉进行根管预备,对照组58个患牙,采用不锈钢K锉根管预备,两组均以常规侧方加压法进行根管充填,在治疗前、中、后应用X线牙片了解根管数目、形态、确定根管工作长度、判断治疗效果。结果:对118个磨牙根管充填后拍摄X线牙片及观察术后反应,实验组根管成形及充填满意率85%,术后急症反应率3.33%,对照组满意率62.07%,术后急性反应率为15.5%。经x2检验,两组根管成形及充填满意率有显著性差异(P<0.01),术后急症反应率有显著性差异(P<0.01),实验组明显优于对照组。结论:手用ProTaper根管扩大系统联合镍钛K锉可有效提高老年人根管治疗的效果。
OBJECTIVE: To evaluate the effectiveness of hand-held ProTaper root canal augmentation system combined with Nitinol K-file for root canal therapy in the elderly. Methods: One hundred and eleven patients with chronic periapical periodontitis were randomly divided into two groups. The experiment group included 60 teeth, and the ProTaper root canal enlargement system and NiTi K file were used for root canal preparation. In the control group, 58 teeth, The root canal was filled with stainless steel K-file root canal. Both groups were treated with conventional lateral compression method for root canal filling. X-ray teeth before, during and after treatment were used to understand the number and shape of root canal, determine the working length of root canal, effect. Results: The root canal of 118 molars was filled with X-ray teeth and the postoperative reaction was observed. The satisfactory rate of root canal formation and filling in the experimental group was 85%, the postoperative acute reaction rate was 3.33%, the satisfaction rate of the control group was 62.07% The acute response rate was 15.5%. There was significant difference (P <0.01) in the satisfactory rate of root canal formation and filling between the two groups (P <0.01). The experimental group was significantly better than the control group. Conclusion: The combination of ProTaper root canal enlargement system and NiTi K file can effectively improve the effect of root canal therapy in the elderly.
