Technological advancement has led to the development of concentrated platelets, by means of centrifugation, popularly known as Platelet concentrates which seem to be a convenient approach to obtain autologous growth factors. Locally delivered platelet concentrates are supposed to increase the proliferation of connective tissue progenitors to stimulate fibroblast and osteoblast activity and enhance angiogenesis, all of which are fundamental to tissue healing and regeneration. Several techniques for platelet concentrates are available, each method leading to a different product with different biology and potential use. Different platelet concentrates are classified, depending on their leucocyte and fibrin content. Conventional platelet rich plasma (PRP), also known as first generation platelet concentrate is plasma with a platelet concentration above the normal physiologic levels found in blood. Platelet Rich Fibrin Matrix (PRFM) is an autologous biologic material created by two step centrifugation of whole blood without the use of exogenous thrombin. Platelets isolated, remain intact and retain their growth factor compliment. This allows a more effective, sustained release of growth factors to the wound site following PRFM application. PRFM possesses the ability to enhance tissue repair by isolation, concentration and preservation of autologous platelets in a dense scaffold like fibrin matrix. The viable platelets contain intrinsic growth factors which are probably released in a desired spatial and temporal manner that affect every aspect of soft tissue and osseous healing. Very limited studies have been conducted to assess the regenerative potential of this new modality i.e. PRFM. This study therefore aims at the evaluation of platelet rich fibrin matrix as a potential regenerative material in comparison with open flap debridement in human periodontal intraosseous defects.
