Bilateral talon cusp in permanent maxillary lateral incisors: A case report, clinico-pathological review and proposal of an integrated classification

Abstract

Talon cusp (TC) is an uncommon developmental anomaly resulting from the invagination of inner enamel epithelium cells. It is primarily seen in people of Asian descent. Maxillary lateral incisors are the teeth most commonly affected by this dental malformation. Early detection and management are pertinent to prevent complications that may be associated with the TC. We describe the successful diagnosis and management of a rare case of nonsyndromic bilateral TC in permanent maxillary lateral incisors with conservative therapy. Further, while discussing the case, we present a brief clinicopathological review on TC and also propose an “integrated classification of talon cusp (ICTC) to describe the morphological aspects as well as indicate the severity and difficulty in the management of cases. An early specific diagnosis along with multidisciplinary treatment approach is recommended for TC, especially to avoid pulpal complications in teeth.
