PRF and PRP in Dentistry: An Umbrella Review

Introduction: Platelet-rich fibrin (PRF) and platelet-rich plasma (PRP) utilize autologous blood and share the objective of leveraging blood-derived growth factors to enhance the body’s natural healing process. A large extensive use has been made in various branches of dentistry. Methods: A total of 4175 records were identified from the electronic search, specifically 291 from BioMed Central, 3406 from MEDLINE/PubMed, 304 from the Cochrane library databases, and 174 from the PROSPERO register. This review was performed in relation to the PRISMA flow chart and was annotated in the PROSPERO register. Results: In total, 3416 title abstracts were screened, and a total of 40 systematic reviews were finally included in the present umbrella review. Conclusions: Research supports the use of PRF and PRP in different fields of dentistry. This is a huge potential for the patient but also for the doctor as these products are from the patient and have zero cost. However, further studies are needed, especially RCTs, to have clearer evidence on the role of PRF and PRP.
