Platelets play an essential role in hemostasis and tissue regeneration. Supra physiological doses of platelets were adopted in the 1990’s called platelet-rich plasma. Due to drawbacks associated with platelet-rich plasma, a second generation called platelet-rich fibrin was developed. This is a case series of arthrocentesis, extractions, enucleation of cyst, buccal mucosa harvest, and oral antral communication in which platelet-rich fibrin was used to augment the healing process. Some authors found that platelet-rich fibrin accelerates the healing of soft and bone tissue and reduces postoperative pain after extractions. Platelet-rich fibrin is also reported to cause less infection with its use. Lastly, platelet-rich fibrin was injected into the TMJ and a reduction in pain and increase in mouth opening was observed. Platelet-rich fibrin has been demonstrated to exert an anti-inflammatory environment. It has been shown to permit a rapid angiogenesis and is resistant connective tissue that is easy to work with. In conclusion, platelet-rich fibrin can stimulate the recruitment and proliferation of endothelial cells, gingival fibroblast, chondrocytes, and osteoblasts.
