EndoCowboy® File Retrieval
Fractured instruments in root canals pose a significant endodontic challenge, particularly when multiple fragments are involved. This case presented as a highly complex retreatment of tooth 37, with radiographic and clinical evidence of at least two separated files within the root canal system.
One fragment was tightly lodged in the curved section of the mesial buccal canal, complicating its retrieval. After extensive preparation, the removal was finally carried out with repeated use of the EndoCowboy system. The entire procedure required more than one hour due to the curvature and the length of the fragment, which made the removal challenging.
This case highlights the importance of srategic canal preparation, flexible retrieval systems, and patience when managing severely curved canals with retained instruments.
