Deflazacort is a glucocorticoid used as an anti-inflammatory drug. We used deflazacort 30 mg tablet. Patient took a pill once preoperatively (1 hour ago) in third molar surgery.

Placebo is an inert substance or treatment which is designed to have no therapeutic value. Patients took sugar pill for plasebo once one hour before operation.

After the taken a deflazacort pill once preoperatively (one hour ago), local anesthesia was obtained using 2 ml articaine hydrochloride 40 mg/ml with epinephrine 0.01 mg/ml . The horizontal incision was made with no. 15 scalpel blade and a full thickness mucoperiosteal flap was raised. In all surgical procedures, bone removal and/or tooth sectioning were performed under sterile saline irrigation. Following the extraction, granulation tissues were removed, and bleeding was controlled. Finally, the mucoperiosteal flap was repositioned by 3.0 silk sutures.

Patients were requested to mark their pain intensity on a pain assessment form using a visual analoge scale (VAS) ranging between 0 (no pain) to 10 (most severe pain).

Postoperative edema was evaluated by the distance between predetermined facial anatomic landmarks (from the mandibular angle to lateral corner of the eye, base of the nose, labial commissura, and soft tissue pogonion) which was measured with using thread and millimeter ruler.

Postoperative trismus was evaluated by the maximum distance between the incisive borders of the upper and lower right incisive teeth which was measured with a caliper.
