ABSTRACT
Dens evaginatus is a developmental anomaly characterized by the occurrence of an extra cusp shaped as a tubercle projecting from the palatal or buccal surfaces (talon cusp). In the anterior dentition, dens evaginatus is more commonly found in the maxilla and on the palatal surface of the tooth. The authors present a case of dens evaginatus in a maxillary central incisor, in which the evagination was removed and routine endodontic treatment was performed.

A total of 328 periapical x-rays from 105 patients of Mongolian origin, 106 of Negro origin and 117 of Caucasian origin were studied. The Mongolian race showed a greater incidence of three-rooted mandibular molars (15.2% of the Mongolian patients, 7.5% of the Negro patients and 6.8 of the Caucasian patients). There was no statistical difference in relation to sex and the incidence of this extra root.
