The complex root canal system morphology in rare cases can complicate the root canal treatment and cautious management of the case is mandatory. The aim of this case report is to illustrate the successful endodontic management of biradicular maxillary central incisor with the aid of three-dimensional cone-beam computed tomography. A 36-year-old female was referred to the Department of Endodontics with the chief complaint of spontaneous pain in the anterior region of maxilla. Complete clinical examination revealed no tenderness to percussion and palpation and no periodontal pocket was measured. Maxillary right central incisor was sensitive to cold and other adjacent teeth responded within normal limits. Preoperative radiographs showed normal periodontal ligament spaces. By using bisecting angle technique at different angles, the presence of a second root was confirmed based on the Same Lingual Opposite Buccal (SLOB) rule. A diagnosis of irreversible pulpitis by clinical, radiographic, and CBCT examination was made. The entire procedure that has been undergone is described including pulpal and periapical examination together with adjunctive conventional radiography and CBCT, access cavity preparation, root canal shaping, and final obturation. A 1-year follow-up showed asymptomatic tooth and proved CBCT to be useful to manage endodontic anatomic variations. The dental pulp within tooth crown and root canal, also known as root canal system, is deemed to have various morphologies and has been categorized into different classes by many studies. Detecting the variations in the anatomical configuration of the root canal system by various techniques will help to improve the success rate of endodontic treatment. Previous case reports concerning maxillary incisors and their unusual anatomy were also reviewed to identify research gaps and limitations.
