Gemination with Talon's Cusp on Mandibular Central Incisor: An Unusual Occurrence

Gemination, is the attempted division of a single tooth germ by invagination during the growth cycle resulting in a bifid crown. They are found frequently in the primary than in the permanent dentition with a prevalence of approximately 1% and 0.1% respectively. It is most often seen in the maxillary primary incisors and the canines. The Talon’s cusp is a relatively rare developmental anomaly characterized by the presence of an accessory cusp like structure projecting from the cingulum area of the maxillary or mandibular anterior teeth in both the primary and permanent dentition. This anomalous structure is composed of normal enamel and dentin and either has pulp tissue or is devoid of it. Germination of mandibular anterior teeth along with Talon’s cusp is a rare phenomena and very few cases have been reported in literature. We therefore, report a rare case of germination with Talon’s cusp in the mandibular central incisor with review of literature.
