Various anomalies can be observed around the central incisors such as a fused tooth. Despite its rare occurrence, dental management can be difficult. This study presents a treated fused maxillary central incisor treated nonsurgically in single visit endodontics. Cone-beam computed tomography (CBCT) was very helpful to overview the anatomy of this tooth and plan it prior to treatment. The patient consent was obtained and treatment was initiated. The supernumerary part was removed, and double access of each coronal parts were done separately allowing non-surgical root canal treatment of the two roots followed by final composite resin restoration. The patient was referred back to his orthodontist to continue the planned treatment. The patient was recalled after a year and the overall outcome was deemed successful. This report shows the benefits of a multidisciplinary treatment approach and the advantageous use of modern radiographic techniques. benefits of the multidisciplinary treatment approach and the advantageous use of modern radiographic techniques.
