Comparative study between physiological healing vs. the use of platelet-rich fibrin at the time of bone and gingival tissue healing in lower third molar surgeries. Bibliographic Review

Introduction: The extraction of retained third molars can present surgical complications, causing various alterations to the patient, such as pain after the intervention, inflammation during the next 24 to 72 hours, jaw pain, among others. Objective: To compare the effectiveness of physiological healing vs. the use of platelet-rich fibrin at the time of bone and gingival tissue healing in lower third molar surgeries by means of a bibliographic review and thereby identify the properties and factors that promote healing. cicatrization. Materials and methods: Qualitative and descriptive bibliographic review, based on the PRISMA (2020) method, inclusion and exclusion criteria were used, in addition to search strings created using MeSH terms and Boolean operators to search the databases, PubMed, ScienceDirect, and Scielo. Results: A total of 12 scientific articles with valid information for the investigation were obtained. It was determined that platelet-rich fibrin is better than physiological healing for bone and gingival tissue healing in lower third mandibular surgeries. Conclusion: It is concluded that the application of Platelet Rich Fibrin (PRF) promotes the healing process of the tissues and reduces discomfort such as pain, inflammation and bleeding after mandibular third molar surgery, although advanced Platelet Rich Fibrin variants (A-PRF) and leukocyte- and platelet-rich fibrin (L-PRF) are more efficient than simple PRF
