The Clinical Applications Of Platelet-Rich Plasma And Platelet-Rich Fibrin Combined With Photobiomodulation In Regenerative Dentistry: A Literature Review, Maryam Pourhajibagher, Rashin Bahrami, Abbas Bahador

Journal of Dental Sciences

Regenerative dentistry seeks to restore oral tissues through biologically driven therapies that stimulate endogenous healing. Among these, autologous platelet concentrates—namely platelet-rich plasma (PRP) and platelet-rich fibrin (PRF)—serve as reservoirs of growth factors such as platelet-derived growth factor (PDGF), transforming growth factor-beta (TGF-β), vascular endothelial growth factor (VEGF), and insulin-like growth factor (IGF), which promote angiogenesis, cell proliferation, and extracellular matrix formation. Complementing these biological mediators, photobiomodulation (PBM) represents a non-invasive light-based therapy that enhances mitochondrial activity, modulates inflammation, and accelerates tissue regeneration. Accumulating evidence suggests that combining PRP or PRF with PBM produces synergistic effects that surpass those achieved by …
