Management of a Persistent Radicular Cyst in the Maxillary Right Lateral Incisor: A Case Report.

ABSTRACT

A 32-year-old male patient presented with a chief complaint of ongoing endodontic treatment and swelling in the hard palate, specifically in the rugae region. On examination, a soft, non-tender, non-fluctuant swelling was observed between teeth #11 and #12, accompanied by radiographic evidence of periapical radiolucency and perforation. Cone beam computed tomography (CBCT) scans confirmed a well-defined radiolucency in the affected region, indicative of a radicular cyst. Root canal treatment was completed with mineral trioxide aggregate (MTA) obturation during the second visit. An apicoectomy was performed to remove the cystic content, followed by the placement of bone graft material, a platelet-rich fibrin (PRF) membrane, and sutures to facilitate bone regeneration. This comprehensive approach aimed to resolve the periapical pathology and promote tissue healing around the affected tooth.
