Facial and Palatal Talon Cusp on a Mesiodens Associated with Hyperdontia- A Rare Occurrence.

Supernumerary teeth or hyperdontia are those that are additional to the normal complement of teeth. Mesiodens is an extra tooth most commonly seen in the premaxillary region, while talon cusp is a well demarcated additional cusp extending form cingulum or cemento- enamel junction to the incisal edge. It is usually present on labial or palatal surface of primary and permanent anterior teeth. Occurrence of talon cusp on a mesiodens is an uncommon phenomenon. This paper presents a rare case of facial and palatal talon cusp on a mesiodens in association with hyperdontia, reported in a 12-year old girl.
