Abstract
A newer treatment, autologous platelet-rich plasma (PRP), represents a greater similarity to the natural healing process as a composite of multiple growth factors, is safe due to its autologous nature, and is produced as needed from patient blood. PPR is an concentration of platelets and growth factors, including transforming growth factor-beta (TGF-b), vascular endothelial growth factor (VEGF), and platelet derived growth factor (PDGF). The enhancement of tissue healing by the placement of supraphysiologic concentration of autologous platelets at the site of tissue injury or surgery is supported by basic science and clinical studies. Due to the increased concentration and release of these factors, PPR can potentially enhance the recruitment and proliferation of stem cells and endothelial cells. Ozone can promote platelet aggregation and release of grow factors with both mitogenic and chemotactic properties. In addition to use in the treatment of chronic skin and soft tissue ulcerations, application of this method include periodontal and oral surgery, maxillofacial surgery, orthopedic and trauma surgery, cosmetic and plastic surgery, spinal surgery, heart bypass surgery, and burns. A better understanding of platelet function and appropriate clinical use is essential in achieving the desired outcomes of platelet-rich concentrate in clinical applications.
