Abstract
Dens invaginatus and talon cusp are both developmental anomalies of the teeth. The prevalence rate of dens invaginatus in southern Chinese is 0.4%, and that of talon cusp is 2.5%. The dens invaginatus has an enamel-lined cavity intruding into the crown or root, or even into the root apex of the tooth. The talon cusp usually arises from the lingual surface of primary or permanent anterior teeth like an eagle's talon. This article presents a rare case of dentoalveolar abscess in the maxillary left central incisor that has a severe dens invaginatus associated with talon cusp malformation. Surgical extraction is indicated in this tooth because of its complexity of root canal systems in case of endodontic treatment. The extracted tooth was scanned through the use of computed tomography (CT) to examine the inner structure of the invagination and talon cusp. (Taiwan J Pediatr Dent 3(1): 40-45, 2003)
