Talon cusp: a morphological dental anomaly

Abstract

Talon cusp is a rare developmental anomaly that occurs most commonly on the lingual side of the incisors. It may cause various clinical problems, such as occlusal interference, irritation of the tongue, pulpal necrosis, caries and periodontal problems. Genetics is thought to be a major cause for the occurrence of this anomaly. This article reports three cases of talon cusp in three members of the same family. Clinical and radiographic findings of talon cusp in two siblings and the mother are presented. Early diagnosis of talon cusp helps in selecting the correct treatment procedure and avoiding complications.
