Agregados plaquetários e a sua utilização na odontologia

Tissue repair is an attribute of the organism for healing an injury, recovering the affected tissue. Fibrin plays an important role in the tissue regeneration process. It is defined as a fibrous protein that acts in blood coagulation, promoting platelet aggregation in hemostasis. Some platelet aggregates have been used in odontology to improve the tissue regeneration process: Platelet-Rich Plasma (PRP) and Platelet-Rich Fibrin (PRF). This work aims to analyze, through literature review, the properties of platelet aggregates, especially on PRF and its use in odontology. The first generation of autologous platelet aggregates was named Platelet-Rich Plasm. Although it was widely used in the first years of its development, some studies have pointed out limitations related to its use due to the protocols used. So, a PRF has been proposed, a second-generation aggregate that has been increasingly used in odontology, mostly in periodontics, surgery, and implantology. According to this review, it can be concluded that PRF may be a material to be chosen when faster and satisfactory results are sought for healing in implant dentistry periodontics and dental surgeries in general. Besides this, it is an easily accessible autologous material of low cost. However, because it is a relatively new technique, further studies are necessary to support its applications.
