Clinical Applications
Platelet-Rich Fibrin (PRF) is being investigated across multiple medical and dental specialties, with the strongest evidence base in periodontal and oral surgery applications.
Periodontal and Oral Surgery
PRF shows the most established clinical applications in periodontal therapy. Clinical trials have evaluated its use as an adjunct to open flap debridement for treating periodontal intrabony defects, with systematic reviews and meta-analyses examining its efficacy. Studies have compared PRF membrane combined with demineralized freeze-dried bone allograft (DFDBA) versus DFDBA alone for managing intrabony defects, suggesting potential benefits for periodontal regeneration.
For gingival recession treatment, completed clinical trials have investigated coronally advanced flap procedures with and without PRF. The therapy is also being studied for post-extraction healing, with trials examining its effect on complications and healing following tooth extraction.
Dental Implantology and Bone Regeneration
Research has explored PRF variants in implant dentistry, particularly for cases with challenging bone anatomy. Studies have compared different PRF formulations (such as H-PRF bone blocks) with traditional bone grafting materials like deproteinized bovine bone mineral (DBBM) for immediate implant placement in thin buccal bone situations. Case reports describe two-stage sinus lift procedures using Alb-PRF gel for bone regeneration enhancement.
Endodontic Applications
Emerging research examines PRF extracts for endodontic therapy, specifically investigating how A-PRF(+) extract affects dental pulp stem cells in cases of irreversible pulpitis. Active clinical trials are evaluating PRF as a scaffold material for regenerating immature necrotic permanent teeth.
Other Applications
Limited studies have explored PRF in gastrointestinal surgery, with research on leukocyte-platelet rich fibrin combined with chitosan for colon anastomosis healing in animal models. Case series have reported intra-articular injection of injectable PRF (i-PRF) for temporomandibular joint internal derangement.
Clinical trials have also investigated PRF for wound healing applications, including palatal wound healing compared to hyaluronic acid dressings, and a Phase 4 trial examined PRF treatment for diabetic foot ulcers.
Evidence Limitations
While PRF is being studied across diverse clinical applications, the evidence base varies significantly by indication. The strongest research foundation exists for periodontal applications, while evidence for other uses remains more limited, often consisting of case reports or small studies. Many applications are still in early investigational phases.
