Talon cusp is a rare dental abnormality where an extra cusp develops on the inner side of the upper incisors starting from the neck of the tooth. It was first described by Mitchell in 1892 and the term ‘Talon Cusp’ was coined by Mellor and Ripa in 1970 due to its resemblance to an eagle’s talon. It can be observed as a single malformation or may be associated with other genetic disorders.
Sites of Occurrence
It is most commonly observed on the palatal surface of the upper lateral incisors followed by the upper central incisors, the lower incisors and then the upper canines.They are mostly seen on the permanent teeth. However, some reports state the incidence of talon cusp in milk teeth as well.
Treatment depends on the type of problems posed by the talon cusp and the extent of its growth.
