Canal Transportation and Volumetric Dentin Removal Abilities of Ni-Ti Rotary File Systems in Curved Primary Root Canals: CBCT Study

Current improvements in nickel-titanium (Ni-Ti) rotary file systems have created a paradigm shift the root canal therapy of primary teeth. Therefore, it is necessary to perform comprehensive evaluation regarding efficiencies newly manufactured instruments for different parameters. The current study was conducted evaluate abilities RaceEvo, R-Motion, ProTaper Gold (PTG) curved canals with regard patterns transportation and volumetric dentin removal by using cone-beam computed tomography (CBCT). Two experimental sets were designed following determination groups pre- post-operative CBCT data: removal. highest amount significantly detected PTG group comparison RaceEvo R-Motion groups. When mean values data analyzed across all groups, again exhibited value volumetrically, compared manual instrumentation It possible state that could be used as reliable alternatives without causing adverse mechanical effects maintaining original anatomy instrumentation, high diagnostic sensitivity pediatric endodontics when alternative methods are not adequate.
