Dexamethasone-PRF in Mandibular Third Molar Surgery: Effect on Pain, Edema, and Trismus (DEXPRF-3M)

Application of autologous platelet-rich fibrin (PRF) prepared from peripheral blood with or without the addition of 4 mg dexamethasone directly into the blood collection tube prior to centrifugation. PRF was applied into the extraction socket after impacted mandibular third molar surgery. The test group received PRF prepared from blood enriched with dexamethasone, while the control group received standard PRF without dexamethasone, to evaluate postoperative pain, edema, and trismus.
