Periapical lesions, commonly resulting from endodontic infections, present a considerable clinical challenge in dentistry. When standard root canal therapy does not effectively resolve these lesions, surgical intervention becomes necessary. Investigations such as radiography play an important role in navigating such lesions. This case report focuses on a failed root canal treatment in the upper incisor region, complicated by the development of a persistent periapical lesion. It details the surgical management through enucleation, addressing both the affected tooth and the associated pathology. The report emphasizes the crucial role of accurate diagnosis, suitable imaging, and thorough treatment planning in managing periapical lesions and highlights the importance of routine radiographic assessment, particularly in asymptomatic or inadequately responding endodontic cases.
