Effect of Reduced Centrifugation Time on Leukocyte, Platelet, and Growth Factor Levels in Platelet-Rich Fibrin (PRF) Prepared Using Low-Speed Relative Centrifugal Force (RCF): An Ex Vivo Study

A 4-minute centrifugation at 600 rpm suggests improved cellular retention and trends toward higher growth factor concentrations by enhancing leukocyte, platelet, and VEGF concentrations, with a modest TGF-β increase. This protocol offers potential biochemical enhancement with improved chair-side efficiency, warranting further clinical validation.
