Abstract

Paramolar tubercle is a rare developmental dental anomaly defined as an additional cusp occurring on the buccal or lingual sur-faces of the molar. Permanent molar fused with paramolar tubercles can be a cause of difficulty in root canal treatment. Therefore, proper understanding of these variations is important in order to ensure successful endodontic treatment. Cone beam computed tomography (CBCT) can be helpful to understand anatomy of complicated cases. This case report describes nonsurgical endodontic treatment of maxillary second premolar fused with paramolar tubercle.
