Dehydration Induces Cracking in Root Dentin Irrespective of Instrumentation: A Two-dimensional and Three-dimensional Study

Water loss strongly affects the mechanical behavior of dentin. Micro–computed tomography (μCT) studies exploring the influence of endodontic procedures on root cracking often lack information on the hydration state of the scanned samples. This study explores the relationship between dehydration and crack formation in root dentin with and without endodontic instrumentation.
