Shen Y, Hieawy A, Huang X, Wang Z, Maezono H, Haapasalo M. Fatigue Resistance of a 3-dimensional Conforming Nickel-Titanium Rotary Instrument in Double Curvatures. J Endod. 2016; In Press
Conclusion: TruShape was superior to ProFile and Vortex Blue in terms of fatigue resistance in double curvature canals.

Conclusion: The limited (up to 0.7 %) retained radicular dentin in the TruShape versus the Vortex cavity proved effective in reducing masticatory stresses.

Conclusion: TruShape provided conservation of dentin by limiting dentin removal and in the absence of substantial canal transportation. In the present study, the use of TruShape in the mesial canals of mandibular molars did not result in decreased amounts of unprepared canal surface.

Conclusion: TruShape files removed significantly more canal wall bacteria than Twisted Files when used without an antibacterial irrigant; the latter is required to decontaminate dentinal tubules.
