With increasing life expectancy and the more frequent use of medications associated with osteonecrosis, the incidence of MRONJ continues to rise. To date, there are no uniform treatment standards with scientifically proven effectiveness for this condition. To evaluate the impact of platelet-rich fibrin (PRF) on the outcomes of MRONJ treatment and to identify factors that may influence the effectiveness of PRF therapy, we conducted a comparative prospective study including 22 patients divided into two groups: patients treated with PRF and patients treated without PRF. PRF was prepared according to the PRF Duo Quattro Process protocol for PRF (Nice, France). The study was registered at ClinicalTrials.gov (NCT07464678). The following parameters were assessed: age, smoking status, gender, lesion location, body mass index (BMI), C-reactive protein (CRP) concentration, pain intensity, presence or absence of fistulas, soft tissue healing and radiological findings. Patients were evaluated preoperatively and postoperatively at 14 days, 6 weeks, and 6 months. The study demonstrated a reduction in pain after surgery among patients treated with PRF. In addition, the use of PRF resulted in improved healing outcomes in patients with elevated CRP. Higher BMI was associated with poorer therapeutic response to PRF. Improvements in soft tissue healing and disease stage were observed in the PRF group; however, these differences did not reach statistical significance. All findings should be interpreted with caution due to the limited sample size. There is still no standardized treatment for MRONJ. The use of platelet-rich fibrin as an inexpensive and safe adjunctive therapy may provide clinical benefits for patients, particularly through a significant reduction in pain. Further large-scale, multicenter studies are required to confirm these findings.<\/jats:p>","DOI":"10.3390\/ijms27083654","type":"journal-article","created":{"date-parts":[[2026,4,20]],"date-time":"2026-04-20T09:37:42Z","timestamp":1776677862000},"page":"3654","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Platelet-Rich Fibrin in Surgical Wound Healing of Medication-Related Osteonecrosis of the Jaw: A Pilot Clinical Study"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0588-8331","authenticated-orcid":false,"given":"Aleksy","family":"Nowak","sequence":"first","affiliation":[{"name":"Department of Maxillofacial Surgery, Poznan University of Medical Sciences, 49 Przybyszewskiego St., 60-355 Poznan, Poland"},{"name":"Department of Dental Surgery, Periodontology and Oral Mucosa Diseases, Poznan University of Medical Sciences, 70, Bukowska St., 60-812 Poznan, Poland"},{"name":"Doctoral School, Poznan University of Medical Sciences, 61-701 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Rudzka","sequence":"additional","affiliation":[{"name":"Orthodontic Clinic at University Center of Dentistry and Specialist Medicine, Poznan University of Medical Sciences, 60-812 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Piotr","family":"Skrzypczak","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Poznan University of Medical Sciences, Szamarzewskiego 62 St., 60-569 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Krzysztof","family":"Osmola","sequence":"additional","affiliation":[{"name":"Department of Maxillofacial Surgery, Poznan University of Medical Sciences, 49 Przybyszewskiego St., 60-355 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marzena Liliana","family":"Wyganowska","sequence":"additional","affiliation":[{"name":"Department of Dental Surgery, Periodontology and Oral Mucosa Diseases, Poznan University of Medical Sciences, 70, Bukowska St., 60-812 Poznan, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ahdi, H.S., Wichelmann, T.A., Pandravada, S., and Ehrenpreis, E.D.
