Objective To evaluate the clinical effect of the use of pathfile and protaper nickel-titanium instruments for machine in root canal preparation.Methods A total of 200 patients suffering from pulpitis and periapical that needs root canal treatment was randomly divided into two groups according to treatment order (100 patients/each group).The experimental group was used pathfile and protaper in root canal preparation,and filled with warm gutta vertical condensation.The control group was used protaper root canal preparatory standards method,and filled with warm gutta vertical condensation.The required time of two sets of root canal preparation and the number of equipment broken were recorded,and X-ray film at the preoperation intraoperation and postoperation were used to evaluate effect of preparation and root filling.Results In the root canals prepared of the two groups,no issued offset,no side wear,no step-forming,and no position changed of the apical foramen were occurred,which was consistent with preperative X-ray film.One case was occurred fracture of instrument in the experimental group and the control group,it was Slfile.Tooth position was right mandibular,second molar nearly the root apical 1/3,and upper left second molar mesial buccal root apical position.The root canal preparation time of experimental group was significantly shorter than the control group[the front teeth:(4.73 ± 1.12) min vs (6.32 ± 1.84) min,t =2.243,P ＜0.05; the premolars:(7.83±1.23)min vs (10.25±2.68)min,t =2.475,P ＜0.05; the molars (10.14 ± 1.18) min vs (15.43 ± 5.94) min,t =2.991,P ＜ 0.01].Postoperative X-ray showed that 2 cases were occurred small amount of paste overfilled,the root canal closed tight,no less filling; and 3 cases of the control group occurred paste overfilled,no less filling too.Conclusions The use of nickel-titanium instruments pathfile and protaper for machine in root canal preparation is feasible,and improves the efficiency of root canal preparation.
