Abstract

Background: Molar tooth extraction is a common dental procedure, yet it can pose significant challenges for older adults due to age-related physiological and pathological factors. In recent years, platelet-rich fibrin (PRF) has gained increasing attention as an adjunct to enhance post-extraction healing. Objectives: To compare the treatment outcomes of mandibular molar extractions performed with or without the application of platelet-rich fibrin in elderly patients at Giong Trom District Medical Center, Ben Tre in 2024-2025. Materials and methods: A controlled clinical intervention study was conducted on 40 elderly patients undergoing surgical extraction of mandibular first and second molars (excluding third molars). Patients were divided into two groups: one receiving PRF application in the extraction socket and the other serving as the control group. Results: Among the 40 evaluated teeth, tooth 36 and tooth 46 accounted for the highest proportions (27.5% each), followed by tooth 37 (25%), while tooth 47 had the lowest frequency (20%). Tworooted teeth represented 72.5% of the sample, and three-rooted teeth accounted for 27.5%. After the first postoperative day, vertical swelling was significantly reduced in the PRF group compared to the control group. Evaluation of soft tissue healing after 7 days, particularly among patients with chronic conditions, revealed a markedly better healing response in the PRF group. The proportion of cases demonstrating good healing was consistently higher in the intervention group compared to the control group. Conclusions: The application of platelet-rich fibrin significantly improves soft tissue healing following molar extractions in elderly patients compared to standard surgical methods without PRF.
