Synergistic Approach to Radicular Cyst Management in an Adolescent: Utilizing Platelet-Rich Fibrin, Demineralized Bone Matrix Xenograft, and Type I Collagen Resorbable Membrane for Optimal Healing.

Dentoalveolar injuries can lead to complications like pulpal necrosis, apical periodontitis, and usually radicular cysts, which are common inflammatory odontogenic cysts often triggered by trauma or infection. Radicular cysts are typically asymptomatic but may cause slow, noticeable swelling. This case report details the surgical management of the same in the periapical region of a maxillary incisor in a 12-year-old female patient. The approach included root canal therapy followed by periapical surgery. The cystic lesion was surgically enucleated, and a combination of platelet-rich fibrin (PRF) and demineralized bone matrix (DMBM) xenograft was applied to enhance healing, alongside a type I collagen resorbable membrane. Follow-up evaluations showed the patient was asymptomatic, with significant periapical healing and almost complete bone regeneration observed on radiographs.
