title: Talon cusp affecting permanent maxillary lateral incisors in 2 family members.
abstract: The term talon cusp refers to a relatively rare dental anomaly in which an accessory cusplike structure projects from the cingulum area or cement-enamel junction. The condition can occur in either maxillary or mandibular anterior teeth in both the primary and permanent dentitions. This article reports 2 cases of talon cusp affecting consanguineous first cousins: a case of bilateral talon cusps on the permanent maxillary lateral incisors of a 16-year-old girl, and a case of talon cusp on the maxillary permanent lateral incisor of an 11-year-old boy. The talon cusps caused clinical problems that were related to caries or occlusal interferences. The presence of the dental anomaly in 2 members of the same family suggests that genetic inheritance may be a causative (related) factor. Examination of relatives could facilitate early diagnosis of the talon cusp and aid in preventing carious and occlusal problems.
