Multidisciplinary Management of Radicular Cyst with Fractured Fragment Reattachment: A Clinical Case Report

Abstract Combined endodontic-periodontal lesions pose a considerable clinical challenge due to the close anatomical and pathological interrelationship between the pulp and periodontal structures. When such lesions fail to resolve following conventional root canal therapy, further intervention is required to address the underlying pathology and promote healing. This report presents a case involving a persistent endodontic-periodontal lesion linked to a periapical cyst. A multidisciplinary treatment plan was implemented, incorporating apicoectomy along with guided tissue regeneration (GTR) and guided bone regeneration (GBR) utilizing a xenograft material. This integrated approach enabled effective debridement, regeneration of periapical tissues, and successful clinical recovery.
