RESUMO
INTRODUCTION: The search to optimize the healing and bone repair processes in oral and maxillofacial surgeries reflects the constant evolution in clinical practice, driven by the demand for increasingly satisfactory results and the need to minimize postoperative complications. OBJECTIVE: To evaluate the efficacy of Platelet and Leukocyte Rich Fibrin (L-PRF) in the healing and bone repair process in oral and maxillofacial surgeries. MATERIALS AND METHODS: The systematic review protocol for this study included the definition of the research question, the domain of the study, the databases searched, the search strategy, the inclusion and exclusion criteria, the types of studies to be included, the measures of effect, the methods for screening, data extraction and analysis, and the approach to data synthesis. Systematic literature searches were carried out on Cochrane databases, Web of Science, PubMed, ScienceDirect, Embase and Google Scholar. RESULTS: The strategic search in the databases identified 1,159 studies. After removing the duplicates with the Rayyan© software, 946 articles remained. Of these, 30 met the inclusion criteria. After careful evaluation based on the inclusion and exclusion criteria, 8 studies were considered highly relevant and included in the systematic review. CONCLUSION: Platelet and Leukocyte Rich Fibrin (L-PRF) has a positive effect on the healing process and bone repair in oral and maxillofacial surgeries.

OBJECTIVE: The aim of this study was to analyze the effectiveness of L-PRF as a healing agent in the postoperative period of third molar extraction surgeries, as well as to investigate secondary effects, such as the reduction of pain, edema and other discomforts after the surgical intervention. MATERIALS AND METHODS: The methodology adopted consisted of carrying out a systematic review of the literature, following the model outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The inclusion criteria were previously established according to a systematic review protocol approved by the Prospective Register of Systematic Reviews (PROSPERO) under number CRD42023484679. In order to carry out a comprehensive search, a search in five databases was carried out, PubMed, Web of Science, Scopus, Cochrane Library and Embase. RESULTS: The search resulted in the selection of randomized controlled trials that conformed to the established criteria. Two authors independently screened the records and extracted the data. The assessment of bias was conducted according to the guidelines recommended by the Cochrane Collaboration, using version 2 of the Cochrane tool for assessing the risk of bias in randomized trials (RoB 2). CONCLUSION: This study demonstrated that L-PRF stands out by providing direct benefits to healing, vascularization and tissue regeneration. CLINICAL RELEVANCE: L-PRF plays an important role in reducing postoperative pain, edema, the incidence of alveolar osteitis and infections after third molar removal surgery, compared to patients who did not undergo the use of L-PRF.
