HIGHLIGHTS Alginate/Chitosan is the second most abundant polysaccharide on earth. PRF (platelet-rich fibrin) potential to play adjunct roles in regenerative medicine. 3D printing grafts can increase wound healing capacity. Prospective of combining with different biomaterials promotes tissue regeneration.

Study design and methods: A Medline search with keywords ‘platelet rich plasma dental’ further filtered using Boolean operators (AND, Or, NOt) and combination of specific keywords as follows: ‘platelet rich fibrin’, ‘platelet rich plasma regenerative’, ‘platelet rich plasma periodontal’, ‘platelet rich plasma extraction’ with a custom range of 10 years was performed, which yielded 88 results ou...

Platelet-Rich Fibrin (PRF) was first described by Choukroun et al., (2001). It has been referred to as a second-generation platelet concentrate, which has been shown to have several advantages over traditionally prepared platelet-rich plasma. PRF has a physiologic architecture that is very favourable to the healing process, obtained due to the slow polymerization process. The development of pla...

Bone formation during fracture repair inevitably initiates within or around extravascular deposits of a fibrin-rich matrix. In addition to a central role in hemostasis, fibrin is thought to enhance bone repair by supporting inflammatory and mesenchymal progenitor egress into the zone of injury. However, given that a failure of efficient fibrin clearance can impede normal wound repair, the preci...

The purpose of this study was to evaluate a new technique of harvesting and preparing autologous platelet gel and autologous fibrin glue (body glue) and to evaluate their effectiveness in stopping capillary bleeding in the surgical flaps of patients undergoing cosmetic surgery. A convenience sample of 20 patients ranging from 25 to 76 years of age undergoing cosmetic surgery involving the creat...

The formation of thrombi in vivo includes the activation of both platelets and the coagulation cascade. Conventional thrombolytic therapy is primarily directed toward the dissolution of fibrin. To evaluate the possibility that platelet activity impairs the lysis of thrombi, we studied the effects of aspirin and platelet-deaggregating prostaglandin E1 on thrombolysis with urokinase. Combined pla...

objectives : platelet preparations are commonly used to enhance bone and soft tissue regeneration. considering the existing controversies on the efficacy of platelet products for tissue regeneration, more in vitro studies are required. the aim of the present study was to compare the in vitro effects of plasma rich in growth factors (prgf) and platelet-rich fibrin (prf) on proliferation and viab...
