Effect of cryogenic treatment on nickel‐titanium endodontic instruments [PDF]
International Endodontic Journal, 2005 AbstractAim To investigate the effects of cryogenic treatment on nickel‐titanium endodontic instruments. The null hypothesis was that cryogenic treatment would result in no changes in composition, microhardness or cutting efficiency of nickel‐titanium instruments.Methodology Microhardness was measured on 30 nickel‐titanium K‐files (ISO size 25) using
