Maíra do Prado, Marcos Cesar Pimenta de Araújo, Heloísa Carla Gusman

Introduction: The retreatment of teeth with endodontic failure associated with the use of silver cone as filling material is still today a reality in the endodontic practice. The present work reports a case of endodontic failure resulting from the use of silver cone and subsequent endodontic retreatment. Case report: The procedure consisted of removing the existing metal-ceramic crown and endodontic retreatment with removal of the silver cone, which was apically sectioned by using ultrasound and clinical microscope. Next, the root canal system was filled and glass-fiber posts and metal-ceramic crown were placed. Conclusion: The use of microscope in association with ultrasound was crucial for performing the retreatment, thus allowing the silver cone to be safely removed without unnecessary wear of the dentinal structure.
