About this trial
This prospective, randomized interventional study aims to compare the postoperative effects of standard treatment (control), platelet-rich fibrin (PRF), and PRF combined with corticosteroid treatment in patients undergoing impacted mandibular third molar surgery. A total of 60 participants will be randomly assigned to one of three treatment groups according to the study protocol. Postoperative pain, facial swelling, and trismus will be evaluated on postoperative days 1, 2, 3, and 7. The findings of this study are expected to provide evidence regarding the effectiveness of PRF alone and PRF combined with corticosteroid treatment in reducing postoperative complications following impacted mandibular third molar surgery.

Treatments tested in this trial
Platelet-rich fibrin (PRF)
Biological/VaccineAutologous platelet-rich fibrin (PRF) prepared from the participant's venous blood by centrifugation at 3000 rpm for 10 minutes, and then placed into the extraction socket immediately after impacted mandibular third molar surgery.
Dexamethasone
DrugDexamethasone (8 mg/2 mL) administered as a single intramuscular injection immediately after impacted mandibular third molar surgery in addition to platelet-rich fibrin (PRF), according to the study protocol.
Amoxicillin/Clavulanic Acid
DrugAmoxicillin/clavulanic acid administered postoperatively according to the study protocol.
Paracetamol
DrugParacetamol 500 mg tablets administered postoperatively for pain control according to the study protocol.
Chlorhexidine
DrugChlorhexidine mouthwash administered postoperatively according to the study protocol.
Treatment groups
Trial outcomes
Primary outcomes
Postoperative Pain
Postoperative pain assessed using a 10-cm Visual Analog Scale (VAS), where 0 indicates no pain and 10 indicates the worst pain imaginable.
Postoperative Swelling
Postoperative facial swelling assessed using a flexible measuring tape by recording the linear distances from the tragus to the pogonion (chin point), the tragus to the corner of the mouth, and the lateral canthus of the eye to the angle of the mandible.
Trismus
Trismus assessed by measuring the maximum interincisal mouth opening (mm) using a digital caliper.
