Dental management of a talon cusp on a primary incisor.
There are many treatment options for the pediatric patient with a talon cusp (TC). The purpose of this paper was to report the case of a TC involving a primary maxillary right central incisor in a 14-month-old male causing displacement of the affected tooth. The etiology of a TC is thought to be a disturbance during the morphodifferentiation stage of tooth development. Clinical problems include: (1) occlusal interferences; (2) esthetic disturbances; (3) accidental cusp fracture; (4) tongue irritation; (5) nursing difficulty; (6) caries; and (7) displacement of the affected tooth. The TC affecting the central incisor was reduced over a period of 4 visits, followed by immediate placement of a 5% sodium fluoride varnish at the conclusion of each reduction visit. Restoration of esthetics and function was evident within 1 month following complete cusp reduction. There were no clinical signs of any problems related to the reduction, and the prognosis was considered to be guarded. The pediatric patient was placed on a 6-month oral hygiene maintenance follow-up.
