title: Labial and lingual talon cusps of a primary lateral incisor: a case report.
abstract: Talon cusp occurs as a result of disturbances during the morpho-differentiation stage of tooth development. It is more common on the palatal surface of the permanent maxillary incisors. It can be unilateral/bilateral, but can also occur on the same tooth. Only 2 published reports exist documenting talons on both labial and lingual surfaces of the same tooth in permanent incisors. The purpose of this case report was to present a rare case of a facial and palatal talon cusp on the primary maxillary right lateral incisor in a 5-year-old girl with bilateral cleft lip. In this case, the morphology of the primary incisor was "+" shaped on occlusal view.
