Abstract: This case describes the presentation of dens evaginatus on a maxillary central incisor in an 8-year-old Caucasian male, its subsequent monitoring and later management. Dens evaginatus is a dental anomaly most commonly noted as an accessory tubercle on the occlusal surface of premolars and the palatal aspect of incisors as a talon cusp. Complications can result in loss of pulp vitality, sometimes causing periapical periodontitis. Clinicians should be aware of the presentation and the advantages of different approaches to the management of dens evaginatus.

Clinical relevance: To raise awareness of dens evaginatus in dental professionals working in primary and secondary care.
