Compare the Centering Ability, Canal Transportation and Root Canal Area Increase of XP Endoshaper, Hyflex CM and K3 XF File System by using Cone Beam: An Original Research.

Objective: Using cone beam computed tomography (CBCT), this study compared three rotary file systems-XP Endoshaper, Hyflex CM, and K3 XF-for centering, canal transportation, and root canal area growth.

Materials And Methods: The rotating file system randomly separated 60 removed human mandibular molars into three groups ( = 20). Manufacturer-recommended root canal instrumentation was done. Specialized software examined pre- and post-instrumentation CBCT scans. Centering ability was measured by canal transportation and root canal area expansion at different levels from the apex.

Results: The Hyflex CM file system had the best centering and the least canal transit at all levels ( < 0.05). XP Endoshaper increased the root canal area the most ( < 0.05). The K3 XF file system had average centering and canal transfer results.

Conclusion: The Hyflex CM system centered well, whereas the XP Endoshaper system increased the root canal area the most. The clinical context and therapeutic goals should determine the rotating file system.
