Evaluation of Platelet-Rich Fibrin (PRF) in Accelerating Periodontal Regeneration

Abstract

Background: Restoring the structure and functionality of the periodontal tissues that have been destroyed as a result of illness is the goal of periodontal regeneration. Because it contains growth factors and cytokines, platelet-rich fibrin (PRF) has become a potential regenerative biomaterial that may improve tissue regeneration and repair. Materials and Procedures: Forty individuals with a diagnosis of chronic periodontitis who were recommended for periodontal regeneration treatment participated in this research. Two groups of patients were randomly assigned: Group A (n = 20) had standard open flap debridement, and Group B (n = 20) received PRF in addition to open flap debridement. At baseline, 3 months, and 6 months after surgery, clinical measures such probing depth (PD), clinical attachment level (CAL), and defect fill were evaluated. Centrifugation was used to create PRF in accordance with conventional procedure, resulting in a fibrin matrix that was enhanced with growth factors and platelets. Results: When compared to Group A, Group B’s clinical indicators significantly improved after 6 months. Group B’s PD reduction was 3.5 mm ± 0.5, whereas, Group A’s was 2.1 mm ± 0.4. In Group A, the CAL increase was 1.8 mm ± 0.2, whereas, in Group B, it was 3.0 mm ± 0.3. Group B had a 45% ±3% bone fill, whereas, Group A had a 28% ± 2% bone fill, according to a radiographic study. Rapid tissue healing was linked to PRF treatment, and there were few postoperative problems noted. Conclusion: In comparison to traditional therapies alone, the supplementary use of PRF in periodontal regeneration greatly improves clinical results, demonstrating superior attachment growth, bone fill, and PD reduction.
