Dental anomalies affecting the teeth are relatively common. Simultaneous occurrence of multiple dental abnormalities in a set of teeth is uncommon and relatively rare. This paper aims to report the novel case of dens evaginatus as a covert expression of incisor supernumerary. Also, the use of cone-beam computed tomography (CBCT) for topographic inference is emphasized for routine use for it justifies the sufficient cost-to-benefit ratio.
