An Endodontic Mishap in Maxillary Lateral Incisor with Two Roots: A Case Report

A 24 year old male was referred with pain and swelling in relation to a previously root canal treated maxillary left lateral incisor. Radiographic examination revealed presence of a second root which was left untreated in the previous treatment. This endodontic mishap had led to the failure of the case. During the retreatment the second canal was detected and cleaned, however considering the amount of bone loss around the second root, it was resected. This case report demonstrates the need for greater attention in treating the root canal of maxillary lateral incisors due to its anomalies, and also the need for thorough evaluation of good quality preoperative radiograph to avoid such mishaps.
