Shaping Ability of ProTaper Universal, ProTaper NEXT and WaveOne Primary in Severely Curved Resin Blocks

The Journal of Contemporary Dental Practice, 2019
Complex anatomy of roots requires endodontic rotary instruments that respect and follow that anatomy. The purpose of this study was to compare the shaping ability of three engine-driven nickel-titanium instruments in severely curved simulated canals.Forty-eight severely curved simulated canals in resin blocks were prepared to an apical size of 25 using
