Dens invaginatus is a developmental anomaly resulting from the infolding of enamel and dentin into the dental pulp. Oehlers’ Type IIIa dens invaginatus poses significant challenges due to its intricate anatomy and frequent association with immature teeth. This case report outlines the nonsurgical management of a nonvital immature maxillary central incisor with Type IIIa dens invaginatus, presenting with a chronic apical abscess and a history of trauma to the associated primary incisor. Treatment involved thorough chemomechanical debridement followed by bio-obturation using calcium-enriched mixture cement. Regular follow-ups revealed complete resolution of the periapical lesion. This case underscores the importance of precise diagnosis, individualized treatment planning, and the application of advanced biomaterials in addressing complex presentations of dens invaginatus. The successful outcome emphasizes the efficacy of nonsurgical techniques in preserving immature teeth while restoring function and aesthetics.
