Abstract Objectives Oral mucosal lesions are prevalent and often cause pain, thus impacting patients' quality of life. Platelet-rich fibrin (PRF) has emerged as a promising autologous biomaterial for wound healing, yet comprehensive evidence regarding its efficacy in treating oral mucosal lesions is limited. This study aims to update the current evidence on the effectiveness of PRF in treating various types of oral mucosal lesions. Materials and methods We conducted a literature search in PubMed, Scopus, Embase, and Web of Science databases until April 2024. The search included studies that investigated the use of PRF in treating oral mucosal lesions. Twelve studies met the inclusion criteria, comprising three case reports, three randomized controlled trials, two animal studies, three split-mouth trials, and one retrospective study. We performed data extraction according to a predefined form. Results PRF was applied in two forms—membranes and injectable gels—to treat a range of oral mucosal lesions, including ulcerative, red and white, pigmented, and potentially malignant or malignant lesions. Compared to control groups or conventional treatments, PRF generally demonstrated superior outcomes regarding faster healing, lesion size reduction, symptom relief, and lower recurrence rates. Histological and molecular analyses from some studies also indicated PRF's regenerative and anti-inflammatory effects. Conclusion PRF shows promise as an effective and safe alternative to current treatments for oral mucosal lesions due to its autologous nature, ease of preparation, and wound-healing capabilities. However, further research is needed to standardize PRF preparation protocols and confirm its long-term efficacy across different lesion types. |
