Management of Traumatic Dens Invaginatus Using Regenerative Endodontics in an Adult Patient

This study details a case report of a 26-year-old patient with a discoloured immature maxillary lateral incisor, linked to type II Dens Invaginatus (DI). The development of the root and apex were affected by pulp necrosis due to trauma. Despite the patient's age, a regenerative endodontic procedure (REP) was selected. The treatment was completed over two visits: the first involved chemomechanical debridement and applying Triple Antibiotic Paste, followed by pulpal regeneration on the second visit. After one year, the follow-up revealed incomplete healing, with no apical closure, root canal wall thickening, or increased root length. However, the periapical radiolucency had significantly decreased in size. Within the study’s limitations, the result demonstrates that REP in immature adult teeth can successfully achieve the primary goal of resolving signs and symptoms along with periapical radiolucency.
