A huge number of studies have demonstrated that platelet-rich preparations applied to surgical sites, injuries, or wounds are effective way to promote soft tissue healing and bone growth. The potential use of platelet rich preparations like Platelet - rich plasma and Platelet - rich fibrin are new boon to dentistry termed under the general acronyms PRP (Platelet-Rich Plasma) or PRF (Platelet-Rich Fibrin), is an important current transversal field of research across many fundamental and clinical disciplines.The third important is PRGF. Plasma Rich in Growth Factor (or PRGF) is a type of plasma enriched of proteins and circulating growth factors able to aid the bone and soft tissue regeneration. PRGF includes plasma proteins and coagulative factors and is then more valuable compared to PRP. There are many scientific literature which cover one or other concise aspect of platelet rich preparation. This review aims at covering all basic definitions, key element, history, preparation, differences between PRF and PRP and applications in a simplified manner.
