Leukocyte-platelet rich fibrin on the treatment of a large paradental cyst: a novel regenerative approach

Abstract

Leukocyte-platelet rich fibrin (PRF) is an autologous biomaterial formed by platelets, cytokines, growth factors and cells imprisoned on a fibrin mesh, produced according to Choukroun's protocol. The aim of the present article was to report the use of PRF, associated with a bone substitute, on the regenerative treatment of a large bone defect resulting from the enucleation of a paradental cyst involving the posterior mandible. The treatment resulted in the maintenance of the bone volume, and radiographic evaluation showed new bone formation after 40 days, suggesting an osteogenic and osteoinductive effect. Also, the current literature was reviewed.
