Dens evaginatus (DE) is an uncommon dental anomaly, There is an extra cusp or tubercle protrudes from the occlusal surface of posterior teeth, as well as the lingual surface of anterior teeth. Tubercles have an enamel layer covering a dentin core containing a thin extension of pulp. Tubercles frequently are susceptible to fractures and pulpal complications. With varying degrees of pulp invasiveness, the treatment to DE include preventive or prophylactic sealant, indirect pulp capping, direct pulp capping, endodontic treatment. Endodontic intervention of permanent teeth with immature roots leaves a tooth with compromised root structure when treating necrotic pulps. Revascularization procedure in recent years is suitable for this kind of case. The radiographic evidence shows continuing thickness of dentinal walls, apical closure, and development of root length.
