Abstract:
Objective To evaluate the clinical efficacy of combined use of Pathfile and Mtwo in the preparation of curved root canals.Methods This study enrolled a total of 90 teeth(313 root canals)that need root canal therapy because of pulpitis or apical periodontitis from December 2013 to February 2014.All root canals were randomly divided into three groups.In group A,both Pathfile and Mtwo NiTi files were used in root canal preparation.In group B,Pathfile and ProTaper were used.ProTaper was employed alone in root canal preparation in group C.The high temperature thermaplasticized inj ectable ver-tical condensation technique was applied in all the three groups.The time of root canal preparation,the number of separated de-vices,root canal transportation and the quality of root canal filling were obtained and compared among the 3 groups.Results In group A,the time of root canal preparation was shortest,(6.01±1.12)min ;there were no instrument separation and ledge for-mation,and the filling rate was highest in group A.The differences were significantly noted in these indexes between group A and groups B,C.Conclusion Combined use of Pathfile and Mtwo for preparation of curved root canals is fast and safe,and the root canal filling is satisfactory.This method is suitable for clinical application.
