Dens evaginatus is an accessory cusp-like projection that forms from the enamel organ and appears as a tubercle on the crown. Its classic presentation is an extra cusp in the central groove or ridge of a posterior tooth, and a similar projection can occur in the cingulum area of the maxillary central and lateral incisors. This description matches the characteristic pattern of dens evaginatus, which is different from a tooth within a tooth (dens invaginatus), a partially split tooth (gemination), or merely an additional cusp not arising in this tubercle pattern. Clinically, these cusps can be fragile and susceptible to wear or pulp exposure, so management often involves protective sealing or restoration, with endodontic considerations if pulp is involved.
