Double talon cusp associated with synodontia: Report of a rare case and review of the literature

The talon cusp is a projection of tooth structure, usually of the cingulum of maxillary incisors (rarely in mandibular incisors), analogous to the dens evaginatus of posterior teeth. It is often associated with various syndromes, signifying its diagnostic importance. We report a rare presentation of...

Description
Summary:The talon cusp is a projection of tooth structure, usually of the cingulum of maxillary incisors (rarely in mandibular incisors), analogous to the dens evaginatus of posterior teeth. It is often associated with various syndromes, signifying its diagnostic importance. We report a rare presentation of facial and lingual talon cusps along with fusion in mandibular incisors. Presence of double talon cusps (facial and lingual) along with synodontia (fusion) in mandibular incisors is an extremely rare phenomenon, and has not been reported before. The teeth in question were fused in an unusual manner creating projections on the labial and lingual surfaces. Patient had no other clinical/radiological abnormalities. Radiographs revealed crowns fused via dentin, with separate roots and distinct root canals. The talon cusps were composed of enamel and dentin. Management is planned to alleviate occlusal disturbance, trauma, and to improve cosmetic appearance.
