Talon cusp: an overview with case reports of 3 clinical variants.

: Talon cusp is a dental anomaly, which is present as an accessory cusp and is seen both in the deciduous and permanent dentition. It may occur unilaterally or bilaterally and has been reported mostly in maxillary teeth, with a few cases occurring in the mandible. Talon cusp is usually asymptomatic; however, there are many clinical problems associated with it. Talon cusp is clinically manifested in three forms: talon, semi-talon and trace talon. In this article, we present four case reports of talon cusp with an overview of different clinical variants of talon cusp, classification, etiopathogenesis, associated syndromes, clinical problems, and treatment modalities.
