title: Endodontic management of horizontally placed molars after gunshot injury to mandible: a case report.
abstract: A 37-year-old man reported to our department with the history of gunshot injury to the mandible 15 years before. His anterior mandible had been resected earlier and bone graft was seen. Intraoral examination of lower jaw revealed 4 remaining mandibular molars. These teeth were severely rotated such that they lay horizontal with respect to the mandibular base. Preoperative Dentascan spiral computerized tomography (CT) of the patient revealed obliteration of the mesial canals of the mandibular right first molar and pear-shaped internal resorption defect in the distal canal of the same tooth. This paper reports the challenging endodontic management of a rare case of severely angulated teeth also exhibiting traumatic sequelae in both roots of the impact tooth. It also highlights the usefulness of spiral CT scan in diagnosis of traumatic sequelae such as pulp canal obliteration and internal resorption.
