Depending on tooth location, usually, dens evaginatus describes an anomaly of posterior teeth and talon cusp as an anomaly of anterior teeth. From the standpoint of developmental, morphological and histological considerations dens evaginatus is a more acceptable term to use and talon cusp should be considered as a subset of dens evaginatus. It mostly occurs as an isolated finding rather than an integral part of any disorder. Two cases of dens evaginatus along with other dental anomalies are reported.
