摘要 目的比较ProTaper机动镍钛根管锉与手持不锈钢K型锉在乳磨牙根管预备中的临床效果。方法对200例需要做根管治疗的患儿,将牙位相同、诊断相同,情况类似的乳磨牙共238颗,按随机的原则分为实验组和对照组,实验组用ProTaper机动镍钛锉,对照组用不锈钢K型锉进行根管预备,比较两组病例根管预备的时间、根管预备的形态,并观察两组根管的充填效果。结果实验组根管预备的时间明显少于对照组,差异有显著性(P<0.01)。根管预备的形态,实验组好于对照组。术后疼痛的发生,实验组(4%)明显少于对照组(17%)(P<0.01)。结论在操作时间、充填形态、术后反应上实验组明显优于对照组。ProTaper机动镍钛锉的使用,能大大缩短乳牙根管治疗的时间,提高根管治疗的效率和效果。 Objective To compare the clinical effect of root canal preparation for primary molars using ProTaper rotary Nikel-Titanium file and stainless-steel K-file instrumentation.Methods 238 primary molars of 200 children that require root canal therapy,with common position,diagnosis and similar condition,were divided into experimental group and control group randomly.The root canal of two group were prepared with ProTaper rotary Nikel-Titanium file or stainless-steel K-file respectively.Comparison were drawn between the two groups by preparing time,morphology of the root canal prepared.and the final obturation.Results Compared with the control group,experimental group need much less time for preparing.There is significant difference between the two group(p0.01).The incidence of ache after root canal therapy in experimental group(4%) is markedly lower than control group(17%)(P0.01).Compared by the root canal morphology,the experimental group is superior to control group,and the difference is statistical significant(P0.01).Conclusion The experimental group is markedly superior to control group with preparing time,obturative morphology and postoperative complications.It can save a amount of time in root canal treatment for primary teeth by means of using ProTaper rotary Nikel-Titanium file,which can markedly enhance the effect and efficiency of the therapy.
