An unusual morphological anomaly in an incisor crown. Anterior dens evaginatus.

Exophytic growth of a portion of the tissue structure is one of the various clinical manifestations of the morphological anomalies that can affect the crown of the anterior teeth. The crown form disorder presented in this paper consists of an asymptomatic bulge on part of the vestibular surface of the tooth, due to enamel and dentine growth, with no radiological evidence of the pulp having extended into the protrusion of mineralised tissues. In this case, it only affects one tooth and is not associated with any other dental morphology or structure disorder, or with any of the syndromes that have been described in association with this anomaly. The term to describe this situation in the anterior teeth is not clearly defined in the relevant literature, which employs various names such as talon cusp, accentuated cingulum (when it affects the lingual or palatal surface) or dens evaginatus (evaginated tooth, evaginated odontome), the term that is always used when it is present in the posterior teeth.
