ABSTRACT
The fracture of endodontic instruments is a common procedural error created during a root canal therapy. Starting from the hand files and up to the use of rotary systems, the root canal therapy is sometimes associated with the fracture of the instruments inside the root canal. The purpose of this work was to report a clinical case of removal of a fractured endodontic instrument in the root canal of a maxillary premolar, when part of this fragment extended through the apical foramen. In this case, a simple and a feasible chairside technique was used for the retrieval of the separated file tip.
