This study was carried out to investigate metallic and non‐metallic debris remaining on endodontic files after ultrasonic cleaning and autoclave processing. Forty‐eight unused rotary and hand endodontic files, including eight different brands, were tested. Instruments were cleaned with ultrasound, autoclaved and before and after each step were observed by scanning electron microscopy (SEM). Adherent debris was analysed by energy‐dispersive X‐ray analysis (EDXA). All of the instruments before ultrasound cleaning were contaminated with metallic and non‐metallic debris. Although most non‐metallic debris was removed by ultrasonic cleaning, most of the metallic debris remained even after the final step of sterilization.
