Dynamic 3D Assessment of Root Canal Morphological Changes Following Endodontic Instrumentation Using Sequential CBCT Imaging

Abstract

Accurate evaluation of root canal morphology is critical for successful endodontic treatment. This study aimed to dynamically assess three-dimensional morphological changes in root canals following endodontic instrumentation using sequential cone-beam computed tomography (CBCT) imaging. Extracted human teeth underwent standardized instrumentation protocols and were imaged before and after treatment. Sequential CBCT scans were reconstructed to generate 3D models, allowing quantitative analysis of changes in canal volume, surface area, and curvature. Results demonstrated significant alterations in canal morphology, highlighting variations associated with different instrumentation techniques. This approach provides a precise, non-destructive method for monitoring root canal modifications, offering insights to optimize clinical protocols and improve treatment outcomes.
