Abstract:
The prognosis for endodontic treatment in teeth exhibiting a complex anatomy is unfavorable if clinicians fail to recognize extra root canals. This case demonstrates the presence of a second canal in the disto-buccal root of a maxillary right first molar. Conventional retreatment followed by endodontic surgery was performed and a 1-year postoperative radiograph shows apparent periapical healing.
