MANAGEMENT OF IATROGENIC ROOT PERFORATION IN TOOTH WITH OBLITERATED PULP CANAL- A CASE REPORT.

Pulp canal obliteration is defined as a deposition of hard tissue within the root canal. The cause of PCO is unknown but is believed to be related to damage to the neurovascular supply of the pulp at the time of injury. Complications of PCO may include pulp necrosis, tenderness on percussion, discoloration, periapical radiolucency in some cases. The endodontic treatment performed under these circumstances poses risk of root perforation, a complication which affects the long-term prognosis of the tooth. This report presents the successful management of an iatrogenic root perforation in a tooth with radiographic evidence of pulp canal obliteration.
