Kottoor, Jojo / Paul, Kuriachan Kottanathu / Mathew, Joy / George, Saira / Mathew, Jain / Roy, Arun
This case report illustrates the nonsurgical endodontic management of a seven-canaled mandibular second molar. The root canal configuration presented as four mesial and three distal canals. Identification of the canal system was made with the aid of magnification, ultrasonics, and multiple angulated radiographs. Postoperative examination at 18 months showed a clinically asymptomatic tooth with resolution of the periapical pathology.
