Non Surgical Endodontic Retreatment in a Teeth with Overextended Obturation Literature Review

Background: Iatrogenic incidents are relatively common in endodontics, but statistically more difficult to happen in upper central incisors. Nevertheless, this problems sometimes affects them as well. Objective: to describe a case of gutta-percha overextension in a 29-year-old Caucasian patient. Methodology: This case report was supported by the following electronic databases: PUBMED Cental, BVs/BIREME, Web of science, Science Direct, Periodic Portal and the Cochrane Library of PROSPERO. Results: The articles collected showed that bacterial contamination associated with iatrogenic procedures are the main responsible for endodontic failures. Conclusions: although the effects of iatrogenic procedures often compromise the patient´s well being, the proper endodontic therapy is enough to reestablish dental health.
