Effect of Autoclave on Surface Topography of Various Rotary Files.

Background: Rotary files are essential tools in endodontic procedures, designed to efficiently shape and clean the root canals. However, repeated sterilization, particularly via autoclaving, may affect their surface integrity, potentially compromising their performance and longevity. This study aims to evaluate the changes in surface topography of various rotary files after multiple autoclave cycles using Scanning Electron Microscopy (SEM).
