Utilizing a new and proprietary method of processing of NiTi wire that results in a Blue titanium oxide layer, DENTSPLY Tulsa’s Vortex Blue™ Rotary Files features the same patented variable helical angle design as the original ProFile® Vortex®. Vortex Blue also offers a leap forward in resistance to cyclic fatigue with a minimum of a 65% improvement over M-Wire® NiTi and a minimum of 99% improvement over standard NiTi. In addition to significantly greater resistance to cyclic fatigue, Vortex Blue delivers at least 42% higher peak torque strength over M-Wire NiTi. Standard NiTi files try to revert of their original shape, but the proprietary processing of Vortex Blue rotary files reduces shape memory, giving the file the ability to naturally follow the curvature of the canal. Vortex Blue Rotary Files are available in packs of six in .04 and .06 tapers and in sizes 15 through 50.
