Platelet-Rich Plasma in the Prevention and Treatment of Medication-Related Osteonecrosis of the Jaw: A Systematic Review and Meta-Analysis.

Abstract

Medication-related osteonecrosis of the jaw (MRONJ) is a significant complication associated with bisphosphonates, impacting jaw osteoclasts, and causing altered bone remodelling. Prevention involves stabilizing systemic pathology, considering antiresorptive therapies, and exploring platelet-rich fibrin (PRF) for wound healing and tissue regeneration. The study aims to assess the efficacy of PRF in MRONJ treatment and highlight research gaps for more robust investigations. Following PRISMA and MOOSE guidelines, this systematic review and meta-analysis included English publications from 2013 to 2023, employing a systematic search in databases such as MEDLINE, Scopus, and Web of Science. Quality assessment used the Cochrane Collaboration's tool and the NOS, with the main meta-analysis concentrating on PRF-treated MRONJ cases, assessing resolution rates, and prioritizing healing outcomes and infection absence as primary endpoints. The study, encompassing 11 articles and 480 participants with MRONJ, demonstrated that in stage 1 procedures, PRF significantly outperformed conventional medical treatments (OR: 2.93, 95% CI: 1.54-5.59, P=0.001), particularly at the mandible site (OR: 1.65, 95% CI: 0.86-3.17, P=0.13). PRF also exhibited significantly superior healing outcomes compared with conventional medical treatments (OR: 4.45, 95% CI: 1.58-12.53, P=0.005), supporting its consideration as a valuable alternative in specific MRONJ management scenarios. This study highlights PRF's effectiveness in early MRONJ interventions and specific anatomic sites, despite acknowledged limitations, emphasizing the need for further research, and supporting its consideration in MRONJ surgical management.
