A novel approach for retrieval of separated endodontic instrument: Two case reports

Abstract

The most common endodontic mishap that eventually occurs during any root canal therapy is the separation of instrument inside the canal. The separated instrument influences the final outcome and prognosis of the root canal therapy. The clinician is confronted with a few options when considering this situation. These options can include leaving the fragment or incorporating the fragment to form part of the final obturation or removal from the root canal. Once the decision is made to remove the separated instrument, the clinician must realize that the procedure can be one of the most difficult treatments to attempt. This case report describes retrieval of separated instrument in the middle to apical third area using ultrasonic tips and braiding technique.
