Rapid endodontic management of type II dens invaginatus using an MTA plug: a case report

Dens invaginatus is an anomaly characterized by an infolding of enamel and dentin that can lead to caries and pulpal death while the tooth is still immature, and present difficulties with diagnosis and treatment. Generally such open apices are managed by long term apexifaction procedures. This article demonstrated rapid management of a maxillary lateral incisor having a type 2 dens invaginatus, necrotic pulp, open apex and very large periradicular lesion using calcium hydroxide for one week prior to placement of a mineral trioxide aggregate (MTA) plug. After setting of the MTA, the remaining canal space was obturated using a warm vertical gutta percha technique. At 6 months follow-up the patient was asymptomatic, the lesion had almost entirely resolved, and, the root was already completely surrounded by bone.
