Efeito da fibrina rica em plaquetas e leucócitos (L-PRF) no processo de cicatrização do alvéolo após extração dos terceiros molares inferiores: revisão narrativa da literatura

Abstract

Surgery to remove third molars is a procedure routinely performed in Dentistry, which is associated with inflammatory events and possible complications. This study aimed, through a narrative review of the literature, to verify the effect of fibrin rich in platelets and leukocytes (L-PRF) in the healing process of the socket after surgical extraction of lower third molars. This is a qualitative descriptive research directed at scientific productions published in the last five years, available in the SciELO, LILACS and PubMed/MedLine databases, which were selected for convenience and relevance in the areas that address the subject of this study. It was observed that the use of LPRF in dental surgical procedures is a technique that has innovated the performance of the dental surgeon. The difference in the use of L-PRF is to accelerate and improve the healing process, providing less morbidity, consequently, greater postoperative comfort in addition to the ease in obtaining the material and low processing cost. This platelet concentrate is an autologous healing biomaterial with great potential for bone and soft tissue regeneration, without inflammatory reactions, and can be used alone or in combination with bone grafts, promoting hemostasis, gradual release of growth factors for a period of seven to 28 days after implantation. Available evidence suggests significant benefits of L-PRF to improve healing and consequently reduce procedure complications; however, it has negligible effect on soft tissue healing after removal of impacted mandibular third molars.
