Abstract
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.
