ABSTRACT:Over extruded root canal filling material or an endodontic instrument can act as a source of irritation and may lead to periapical inflammation and pain. Intentional replantation is considered as one of the treatment modalities with recent studies showing success rate as high as 95%. The present case report describes a case where extrusion of separated endodontic instrument beyond the root apex occurred during retreatment of right lower second molar with overextended root canal filling. Intentional replantation was done with atraumatic extraction of tooth, extraoral removal of over extended root canal filling material and endodontic instrument followed by obturation, reimplantation of tooth in the socket and splinting. At 8month follow up the tooth was firm in the socket with no clinical signs of pain and tenderness. Thus the success rate of intentional replantation is promising with proper case selection and procedural techniques.
