The Evidence-based Effect of Platelet-rich Fibrin in Osteogenesis: A Systematic Review and Meta-analysis

Abstract

ABSTRACT
 Background: Platelet Rich Fibrin (PRF) is a growth factor concentration functioning as an initiator of wound healing and bone regeneration, and it is mainly reported in dentistry rehabilitation and rejuvenation.
 Objective: summarize and analyze the evidence based on the effect of PRF on the bone osteogenesis
 Methods: A comprehensive search was conducted on the bibliographic databases or Medical Subject Headings in the PubMed. The search was conducted among articles that were published between 2010 and 2021. Required article information was extracted from each article by abstract and full paper availability that focuses on the Platelet-Rich Fibrin (PRF) And Osteogenesis. We recruited studies with the design was employed clinical trials with in vitro and in vivo approaches. The only study that provided osteogenesis outcome proceeded to the quantitative analysis.
 Results: Regarding literature search and screening processes, it yielded 24 studies for qualitative assessment and eleven studies for quantitative analysis. Most of the studies performed a combination of PRF with other materials such as Mg ring, BMSCs, Gold nanoparticles, and PDLSCs. It showed that PRF combined with other materials enhanced the osteogenic ability. The assessment of PRF only showed the various result in multiple outcome markers. For the ALP, the mean difference is 1.40 [1.14-1.67] p-value 0.001. It indicates there is a significant effect of PRF application with the increase of ALP. For the RUNX2, there is a significant effect of PRF application with the increase of RUNX2 1.10 [0.93, 1.26]. For OCN, the mean difference of PRF in OCN is 0.77 [0.43, 1.12] p=0.001. It showed a significant effect of PRF application with the increase of OCN. There is also a significant effect of PRF application for TRAP with the declining number of TRAP is -1.59 [-2.96, -0.22] p=0.001.
 Conclusion: PRF combined with other materials showed more promising results rather than PRF only. Moreover, in the assessment of PRF only, it was found that PRF has a significant effect in accelerating bone osteogenesis.

Hybrid protein microspheres and their responsive release behaviors and inhibitory effects on melanin synthesis

“…This also indicates that CaCO 3 is easy to fabricate, showing not only the formation of composite structures but also potential applications in delivery vehicles by enhancing storage stability. 24–26 The preferred properties derived from biodegradability, such as degrading into non-toxic products and having pH-sensitive solubility in acidic environments, are also inspired by the application of diverse additives to simultaneously control crystal nucleation and growth during crystallization. 27,28 In addition to these properties, such as simple synthesis, low cost, safety, and pH-responsive properties, advantages such as a high immobilization surface area and high porosity have shown great potential in the past decade in carrier systems, particularly protein encapsulation, with increasing popularity.…”

Therapeutic efficacy of platelet‐rich fibrin on surgical site wound healing in patients undergoing oral carcinoma resection: A meta‐analysis

“…Recent studies have accentuated PRF's role as a concentrated source of growth factors, acting as a catalyst for both wound healing and bone regeneration, particularly in the context of dental rehabilitation. 4,15 Notably, research has illuminated the augmented osteogenic potential when PRF is amalgamated with other bioactive materials, such as Mg ring, BMSCs, Gold nanoparticles and PDLSCs. 15 This underscores the notion that while PRF as a standalone entity offers substantial therapeutic benefits, its synergistic use with other materials can further amplify the healing outcomes.…”
