  • Title: Dens evaginatus and dens invaginatus in all maxillary incisors: report of a case.
    Author: Vardhan TH, Shanmugam S.
    Journal: Quintessence Int; 2010 Feb; 41(2):105-7. PubMed ID: 20165742.
    Abstract:
    Dens evaginatus is a developmental malformation characterized by the presence of an extra cusp that takes the form of a tubercle arising from the occlusal or the lingual surface of the tooth. It is also referred to as talon cusp in the anterior teeth and Leong premolar in the premolars. Dens invaginatus is a deep surface invagination of the crown or the root lined by enamel, dentin, and pulp. Though many case reports of dens evaginatus and dens invaginatus have been found in the literature, an association of both is a rare anomaly. Only two cases of concomitance of dens invaginatus and dens evaginatus have been reported. This article is a case report of dens evaginatus and dens invaginatus involving all four maxillary incisors in a 25-year-old patient.
