Abstract

The purpose of this study was to compare and evaluate the shaping abilities of various hybrid instrumentation method using constant tapered file systems with ProTaper S1 and the difference between experts and inexperienced clinicians in use of Ni-Ti file. Three hybrid methods used in this study were composed of ProTaper S1 and K- Flexofile (group S), ProTaper S1 and HeroShaper (group H), and ProTaper S1 and ProFile (group P), respectively. The ProTaper - alone method (group C) was introduced as a control group. After canal preparation, the lapse of time was recorded. The images of pre- and post-operative canal were scanned and superimposed. Amounts of instrumented canal widths and centering ratio were measured at apical 1, 2 and 3mm levels and statistical analysis was performed. In this study, both of the group C and S took more time to prepare canals than other groups. Inexperienced operators required more time for the entire preparation with the groups C and H than the experienced (p <0.05). And the centering ratio of group P were preferable to ProTaper-alone method or the hybrid technique using stainless steel files. As such, within experienced operators, group H also showed better results in addition to the group P. Under these condition, the hybrid methods of each the ProFile system and HeroShaper with ProTaper are recommendable comparative to ProTaper -alone method. According to the results, the hybrid instrumentation method is a more appropriate method of canal preparation than single file system for narrow or curved canals.
