Abstract

In recent decades, the potential of PRF has been extensively studied. The number of studies about PRF has increased three times since the year 2012, but the full spectrum of its fundamental properties, such as antimicrobial and anti-inflammatory activity, is not clearly described. In oral and maxillofacial surgery, PRF is described in alveolar ridge preservation, orthognathic surgery, cleft lip and palate surgery, maxillary sinus augmentation, and dental implant placement as demonstrating favorable results and its clinical advantages. The structural complexity, inhomogeneous nature, and clotting ability of PRF make its antimicrobial effect evaluation complicated. Nevertheless, most of the used antimicrobial testing methods are based on antibacterial agent diffusion ability in culture media. Because the oral and maxillofacial region is the most frequent area of PRF application, its antimicrobial activity evaluation also prevails in the oral microbiome. PRF’s biological potential is highly dependent on the specific preparation protocol and methodology used; it should be carefully prepared and kept under proper conditions to keep cellular content alive. PRF’s influence on living cells demonstrates a stimulating effect on bone regeneration, and an angiogenetic effect, and it provides anti-inflammatory activity. According to analyzed studies, PRF demonstrated success in oral and maxillofacial surgery in various methods of application. Antibacterial and anti-inflammatory properties were proven by antibacterial activity against different bacterial species, sustained growth factor, sustained release, and cell activity on the material application. Accurately and correctly prepared PRF can ensure antibacterial and anti-inflammatory properties, and it can be a beneficial clinical tool in oral and maxillofacial surgery.

  • The surface-sealing effect of L-PRF and its release of platelet-derived growth factors (PDGF) accelerate vascularization from the surface to deeper layers.

    “In addition, the surface-sealing effect of L-PRF and its release of platelet-derived growth factors (PDGF) accelerate vascularization from the surface to deeper layers.”

    From Implant-supported fixed prosthodontic treatment for ectodermal dysplasia: a case report (2026) · cites this paper as [25]

    Section 4.2 reports that L-PRF membranes release PDGF-AB and describes proangiogenic effects of PRF in vitro. It does not establish a surface-sealing effect or show that these effects accelerate vascularization from the surface into deeper layers. (LLM, conf=0.84)

  • The porous fibrin scaffold of L-PRF provides mechanical support for soft tissue healing, helping to maintain peri-implant keratinized tissue stability.

    “The porous fibrin scaffold of L-PRF provides mechanical support for soft tissue healing, helping to maintain peri-implant keratinized tissue stability [25].”

    From Implant-supported fixed prosthodontic treatment for ectodermal dysplasia: a case report (2026) · cites this paper as [25]

    The Introduction describes PRF as a three-dimensional structure that facilitates cell adhesion and proliferation, and §2.5 reports increased keratinized mucosa around implants after L-PRF membrane treatment. The paper does not establish that mechanical support from a porous fibrin scaffold maintains the long-term stability of peri-implant keratinized tissue; it reports a gain in tissue width at six months. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
