title: Facial talon cusp on mandibular incisor: a rare case report with review of literature.
abstract: Talon cusp is a relatively rare developmental dental anomaly thought to arise as a result of evagination on the surface of a tooth crown before calcification has occurred. It is characterized by cusp-like projections from the cingulum area, or cemento-enamel junction of maxillary or mandibular anterior teeth, in both the primary and permanent dentition, usually observed on the lingual surface of the affected tooth. The cusp may or may not contain an extension of the pulp. The etiology remains unknown. The incidence is 0.04-8%. Any tooth may have a talon cusp but most of the cases involve maxillary lateral incisors. The anomaly has been reported to be rare especially when it occurs on mandibular teeth. This article reports a case of talon cusp on permanent mandibular central incisor that too on facial aspect which makes it a rare entity.
