Abstract

Dental anomalies can occur in primary and permanent dentition, and include fusion, germination, concrescence, dens evaginatus, and dens invaginatus. It is possible for a dental anomaly to induce pulp infection which is generally treated in non-vital teeth by means of a root canal procedure. Here, we present two similar cases that received surgical treatment for radicular cyst arising in an anomalous canine tooth in the maxilla without root canal treatment or tooth extraction. Histopathological results of excised specimens confirmed the diagnosis of radicular cyst. Follow-up examinations showed no recurrence in either case at 6 months postoperatively. Early diagnosis and treatment of dental anomaly is important for preventing pulp infection. Furthermore, computed tomography is useful for diagnosis and evaluations of the size and location of the cystic lesion, as well as determining the optimal surgical modality.
