White Paper: Cyclic Fatigue Resistance

In the endodontic literature, significant attention has been devoted to and much has been written about cyclic fatigue — undoubtedly because it has been reported to be the leading cause of file separation. The sheer volume of rhetoric from file manufacturers seems to single out fatigue resistance as the strongest marker of a file’s performance. But is there more to the story of endodontic file functionality? Dr. Landwehr examines this question in depth in the new white paper, “We’ve Been Looking at Cyclic Fatigue Resistance All Wrong: A Broader perspective on endodontic file functionality.”
