The autologous platelet rich fibrin: A novel approach in osseous regeneration after cystic enucleation: A pilot study

Context: The platelet rich fibrin (PRF) is second generation platelet concentrate that has been widely used and researched for stimulation and acceleration of soft tissue and osseous healing. Its continuous delivery of growth factors and proteins mimic the need of physiological wound healing and regenerative tissue processes. Aims and Objectives: The aim of this study was to evaluate the efficacy of PRF in osseous regeneration after enucleation of cystic lesions. The objectives of this study were: (1) To evaluate osseous regeneration radiographically with the use of PRF in intrabony defects after cystic enucleation. (2) To evaluate the degree of bone density in intrabony defects with the use of PRF postoperatively after 1 st , 3 rd , and 6 th months. Subjects and Methods: 10 cases of cystic lesions were treated using PRF after cystic enucleation. Follow-up radiographs (orthopantomogram) were taken 1 st , 3 rd , and 6 th months postoperatively. Bone density was measured with grayscale histogram using Adobe Photoshop 7.0 software. Results: The subsequent follow-up examinations revealed progressive, predictable, and significant radiographic osseous regeneration. Conclusion: The use of PRF in management of cystic lesions seems to be a novel therapeutic approach promoting faster osseous regeneration within 6 months postoperatively however further study is required with larger sample size and with a control group.
