Trouble Curve: Endodontic Management of Severely Curved Root Canal System - A Case Report

Dilacerations are developmental anomalies characterized by an abrupt deviation in the longitudinal axis of a tooth. They may occur either in the crown, between the crown and root, or in the root. Although not so common, impacted tooth exhibiting root dilaceration pose a diagnostic and treatment challenge to the clinician. Common causes of treatment failures in such cases are primarily related to procedural errors such as ledges, fractured instruments, canal blockages, zip and elbow creations. Knowledge of tooth anatomy and its variations is essential for the success of endodontic treatment. A detailed and thorough assessment of preoperative radiographs along with careful approach yielded into a safe and a successful endodontic treatment of such teeth. This case describes a successful endodontic management of dilacerated mandibular right second premolar.
