Management of a facial talon cusp on a maxillary permanent central incisor: a case report and review of the literature.

Background: A talon cusp is a morphologically well-delineated accessory cusp. This case report discusses the unusual appearance of a talon cusp on the facial surface of the maxillary right permanent central incisor, which was conservatively treated and followed up for a period of 1 year.

Methods: A 21-year-old female was referred for the treatment of a maxillary right central incisor that caused an esthetic problem. Intraoral examination and radiographic and computerized tomographic investigation indicated that there was no connection between the pulp chamber, a "V"-shaped radiopaque structure, and three radiolucent globe areas. The accessory cusp was treated by selective cuspal grinding, followed by resin-based composite placement. The restoration was clinically evaluated 1 week after placement, as a baseline, and after 1 year. The restoration did not exhibit postoperative sensitivity at the 1-year evaluation. No difference was observed in the color match, marginal discoloration, marginal adaptation, or anatomic form compared with the baseline evaluation.

Conclusion: The management and treatment outcome of a talon cusp depends on its size, presenting complications and patient cooperation. The present case report outlines the conservative management of a talon cusp.

Clinical Significance: This paper outlines a viable esthetic treatment option and a review of the relevant literature with regards to managing a facial talon cusp.
