Abstract：Objective To investigate the clinical effect of the machine-made ProTaper nickel-titanium file and stainless steel k file in the root canal treatment of molars.Methods A total of 112 patients with 120 teeth were selected from January to December 2017 for root canal treatment of molars in our hospital.The patients were randomly divided into nickel-titanium file group(56 cases,61 teeth)and stainless steel group(56 cases,59 teeth)according to the order of their visit.They were treated with ProTaper nickel-titanium file and stainless steel k file respectively.The root canal treatment effects of the two groups were compared.Results The root canal preparation time and filling time of nickeltitanium file group were significantly lower than those of stainless steel group,and the good rate of root canal preparation shape of nickel-titanium file group was significantly higher than that of stainless steel group,the differences were statistically significant(P<0.05).The separation rate of the nickel-titanium file group was lower than that of the stainless steel group,and the filling rate of the nickel-titanium file group was obviously higher than that of the stainless steel group,the differences were statistically significant(P<0.05).There was no statistically significant difference in the pain rate between the two groups at 1,3 h after root canal surgery(P>0.05).The pain rates at 24,72 h after operation in the nickel-titanium file group were significantly lower than those in the stainless steel group,the differences were statistically significant(P<0.05).Conclusion The machine-made ProTaper nickel-titanium file has good clinical effect in molar root canal treatment,shortens root canal preparation and filling time,can improve the good rate and just filling rate of root canal preparation shape,reduces the incidence of postoperative pain,is safe and reliable,and is worthy of clinical recommendation.
