Résumé
Endodontic retreatment is a considered as a comprehensive field, divided into various categories such as coronal disassembly, removing obturation materials, locating previously missed canals, etc. This field of endodontics has its own technologies and techniques that are required to achieve clinical success. Because the field of non-surgical retreatment is comprehensive, this case report will limit its focus to the removal of the post. Removal of posts from endodontically treated teeth is a major obstacle in the retreatment of teeth having recurrent pathology, which often leads to the extraction of a tooth that might have been saved with endodontic retreatment. This case report shows the non-surgical endodontic retreatment of incompletely obturated maxillary central incisors by removal of metallic posts.

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.
