Bifacial Talon Cusp Presenting with Dens Invaginatus: A Case Report

Talon cusp is an uncommon odontogenic anomaly. Due to its resemblance to an eagle’s talon, it was named as “talon cusp”. Talon cusps occur most commonly on palatal surfaces of permanent incisors. Bilateral and bifacial talon cusp is an extremely rare occurrence. The etiology of talon cusps remains unknown, though it is thought to be a combination of genetic and environmental factors, developmentally result of an outfolding of the enamel organ or hyperproductivity of the dental lamina. Dens invaginatus is a developmental anomaly which is formed byfolding the enamel-dental organ through the pulp chamber during the teeth development. In this case, bilateral talon tubercle and bifacial talon tubercle with dens invaginatus in the same tooth was reported.
