Objectives: This study aims to compare hand stainless steel K-files andNickel titanium Profile 0.04 taper 29 series rotary instruments in root canalpreparation on permanent premolars. For their efficiency in canals shapingwith maintenance of original canal shape, procedural errors that occur duringpreparations of the canals or the instruments and time consumed in canalspreparation by both methods.Materials and methods: About 46 freshly bilaterally extracted firstpremolars for orthodontic purpose were selected. They were further dividedinto two groups, each group comprise 23 teeth with sum of 34 canals, groupI and group II. In group I teeth were prepared with hand stainless steel kfilesand group II were prepared with profile 0.4 taper series 29 rotary files.Impression material were introduced to the lumen of the prepared canals andthe three dimensional shape of the prepared canals were assessed undermagnification of stereomicroscope to assess the efficiency in preparingcanals including canal smoothness, flow and taper.Results: results showed significantly shorter preparation time for Profile0.04 taper than that of K-file. During canals preparations, about 8.8% ofcanals prepared with hand K-file showed canal blockage, change of workingdistance appeared in 23.5% of canals prepared with K-file and 11.7% incanals prepared with Profile. Failed instruments were significantly higher inK-files; the failure was in the form of deformation in most of cases. Profilesfailed instruments were in the form of fracture and no deformation detected.5Both systems showed unsatisfactory quality of walls smoothness and flow.Good taper characteristic were highly significant in K-files preparations.Conclusion: Profile 0.04 rotary files prepared canals quicker than hand Kfilesand showed less instruments failures. Stainless steel K-file showedbetter results in regard to canals taper, suggesting the use of a technique thatcombines the two systems in canals preparation to overcome problemsassociated with each system
