Objective: contrast of hand with ProTaper nickel titanium file with the standard stainless steel K file in root canal preparation in clinical efficacy. Methods: 160 cases of patients with a total of 160teeth were randomly divided into experimental group and control group. The experimental group used ProTaper hand ProTaper nickel titanium files of crown and root development to method for root canal preparation, the control group with ISO standard stainless steel K file and G drill by step-back technique in root canal preparation. Cold gutta-percha lateral condensation method RCT. Evaluation of root canal preparation time, postoperative reaction and root canal filling effect. Results: in the experimental group, preparation time is shorter than the control group; after root canal treatment response in experimental group than that in control group; root canal filling proper filling rate of experimental group was higher than that of control group. Conclusion: ProTaper shortening root canal preparation time, improve work efficiency, reduced postoperative pain, root canal filling with high quality.
