Abstract

Since its introduction in 2001, multiple platelet-rich fibrin (PRF) centrifugation protocols have emerged, but the variations in growth factor release that result from these protocols remain unclear. This review aimed to evaluate growth factor release across three PRF protocols: leukocyte-PRF (L-PRF), advanced-PRF (A-PRF/+), and injectable-PRF (i-PRF). A comprehensive search was conducted using the MEDLINE and Embase databases, identifying 14 studies that met the inclusion criteria. Due to significant heterogeneity in study designs and methodologies, a meta-analysis was not feasible. However, our findings suggest that lower-speed centrifugation protocols, such as A-PRF/+ and i-PRF, tend to provide a more uniform cell distribution and sustain higher growth factor release over time compared to the conventional L-PRF protocol. Despite these observations, the current evidence is insufficient to draw definitive conclusions about the growth factor release levels among L-PRF, A-PRF/+, and i-PRF. Further well-designed, comparative studies are required to clarify these differences and establish optimal protocols for clinical use.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • L-PRF is rich in cytokines that promote osteoblast proliferation and differentiation and accelerate integration of the graft with host bone.

    “Numerous preclinical and clinical studies have demonstrated that L-PRF is rich in cytokines that promote osteoblast proliferation and differentiation and accelerate integration of the graft with host bone [24].”

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.
