ABSTRACT
Aberrations in the root canal anatomy are a commonly occurring phenomenon. A thorough knowledge of the basic root canal anatomy and its variations is necessary for successful completion of the endodontic treatment. Mandibular second premolars usually have a single root and a single root canal. The incidence of three separate roots itself in this tooth is quite rare, and the presence of four separate roots and four distinct root canals has never been reported in literature so far. The use of spiral computed tomography scan in this rare case greatly contributed towards making a confirmatory diagnosis and successful nonsurgical endodontic management thereafter.

Fusion and gemination are developmental anomalies of the dental hard tissues that might require endodontic and surgical treatment for functional, orthodontic, or esthetic reasons. In this article, we report a rare case of successful endodontic management of unilateral fused mandibular second molar with a paramolar. The rarity with which this entity appears, along with its complex characteristics, often makes it difficult to diagnose and treat. The use of high-end diagnostic imaging modalities such as spiral computed tomography can help the clinician in making a confirmatory diagnosis and determining the treatment plan before undertaking the actual treatment. This case report highlights the usefulness of spiral computed tomography in accurate diagnosis and endodontic management of these unusual cases.
