Check
Talon cusp is a developmental anomaly often present on the incisors and premolars. Most talon cusps have been reported in the permanent dentition; however the primary dentition may be affected. In the anterior teeth, it is characterized by a palatal accessory cusplike projection from the cingulum that extends towards the incisal edge. Though rare, cases of labial talon cusps on maxillary central incisors have also been described. Morphologically this anomaly has a well-delineated cusp that extends at least half the distance from the cementoenamel junction or cingulum area to the incisal edge. The alteration can cause clinical problems such as caries or occlusal interference. Management of the talon cusp varies according to the circumstances of the individual case. Presented is a case of talon cusp in left maxillary central incisor with history of trauma. Tooth was discolored and non-vital, managed successfully by endodontic treatment and walking bleach.
