Revascularization of an immature necrotic permanent mandibular second premolar with dens evaginatus: A case report with 3 years' follow-up

Dentists face a challenge when treating necrotic immature teeth with periapical pathology because apexification techniques leave the tooth vulnerable to fracture. After all, the roots are not matured, and the canal walls are thin. Pulp revascularization is a regenerative endodontic procedure that emerged as a viable treatment for apical closure, continued root development, and dentinal wall thickening with successful clinical and radiographical outcomes. In this case report, an 11-year-old boy complained of pain and associated swelling in the lower left posterior teeth region, diagnosed as pulp necrosis with acute apical abscess of an immature tooth with dens evaginatus (DE). After periapical radiographs, drainage was done through the access cavity, and a regenerative endodontic procedure was performed with the final restoration of composite resin. This report emphasizes the successful management of an immature necrotic permanent mandibular second premolar with DE using a revascularization procedure.
