Pulp revascularization of a severely malformed immature maxillary canine

Abstract

Dens invaginatus (DI) is a dental anomaly exhibiting complex anatomical forms. Because of this anatomical complexity, immature DI teeth with necrotic pulp are difficult to treat via apexification. We used revascularization as an alternative treatment for a patient with DI. An 11-year-old boy visited our clinic with chief complaints of gingival swelling and pain in the left maxillary canine. Clinical and radiographic findings were consistent with a diagnosis of type III DI. Revascularization therapy was performed, and a 24-month follow-up examination confirmed healing of the periapical radiolucency and physiological root formation. (J Oral Sci 58, 295-298, 2016)
