简要总结

Platelet-rich fibrin (PRF) is widely used in regenerative dentistry because of its autologous growth factor release and fibrin scaffold properties. Different PRF preparations may exhibit different biological characteristics that influence their clinical performance. This study aims to compare Albumin-PRF (Alb-PRF), Advanced Platelet-Rich Fibrin+ (A-PRF+), and Leukocyte-Platelet Rich Fibrin (L-PRF) regarding cumulative growth factor release and fibrin degradation. Blood samples obtained from healthy volunteers will be processed to prepare all three PRF types. Growth factor release and fibrin degradation will be analyzed under standardized laboratory conditions.

详细描述

Platelet-rich fibrin products have become increasingly popular in regenerative medicine because they provide a fibrin scaffold capable of releasing multiple growth factors over time. However, differences in centrifugation protocols and preparation techniques may significantly affect their biological properties.

Albumin-PRF is a recently introduced modification that combines heat-denatured plasma proteins with injectable PRF to increase scaffold stability and prolong growth factor release.

This study will compare Alb-PRF, A-PRF+, and L-PRF prepared from the same healthy volunteers. Cumulative release of VEGF, PDGF-BB, and TGF-β1 will be evaluated on Days 1, 3, 5, and 7 using ELISA. Resistance to enzymatic degradation will be assessed by measuring delta D-dimer concentrations following trypsin-EDTA exposure. The results are expected to improve understanding of the biological performance of different PRF formulations.
