Comparison Of Three Different Nickel-Titanium Endodontic Rotary Systems In Shaping Simulated S-Shaped Canals, Elineida Perez
Comparison Of Three Different Nickel-Titanium Endodontic Rotary Systems In Shaping Simulated S-Shaped Canals, Elineida Perez
Master's Theses (2009 -)
Introduction: Preparation error may result during mechanical instrumentation because of the complex anatomy of the root canal. Thus, flexibility and resistance to fracture are ideal properties that endodontic instruments should have. The aim of the study was to compare the shaping ability of three different nickel-titanium rotary instruments in simulated S-shape root canals by measuring transportation and canal volume change CVC. Materials and Methods: A total of 60 S-shaped canals in resin blocks were randomly allocated into 3 groups (n=20): Vortex Blue (Dentsply-Tulsa Dental Specialties), HyFlex CM (Coltène/Whaledent) and EndoSequence (Brasseler USA). Canals were filled with dye and secured in …
