Abstract		Dens evaginatus is a developmental anomaly in which a supernumerary cusp projects from lingual or less frequently labial surfaces of incisors and canines (talon cusp) or from occlusal surfaces of premolars and molars. It has been observed in all parts of the world, the prevalence being the highest in Mongoloid populations. The aetiology is unclear and probably involves both genetic and environmental factors. Dens evaginatus is frequently associated with other dental anomalies; talon cusp can also be part of a syndrome. Dens evaginatus is composed of an enamel layer covering a dentine core which usually contains an extension of pulp tissue. Clinical problems associated with talon cusps include breastfeeding difficulties, unsightly appearance, irritation of the tongue during speech and mastication, traumatic occlusion and displacement of the affected tooth. The developmental grooves delineating a talon cusp are predilection sites for caries or periodontal inflammation. Dens evaginatus of premolars and molars causes traumatic occlusion; wear or fracture of the cusp may result in pulpal exposure and inflammatory complications soon after eruption. Early diagnosis and management of the entity are important if complications are to be avoided.
