Intraosseous vs Submucosal Injection of Dexamethasone

Thirty-eight patients were randomly divided into 2 groups; the intraosseous injection group of dexamethasone (4 mg) and the submucosal injection group. All surgeries were performed by one surgeon. Postoperative pain was evaluated by visual analog scale score immediately after surgery and on postoperative days 1, 3, and 7. Swelling (determined using two linear measurements) were assessed just before the surgery and on postoperative days 1, 3, and 7 by using a digital vernier caliper. Early healing of periodontal soft tissue wound was assessed by using Early Wound Healing Score (EHS) which composed of 3 parameters: clinical signs of re-epithelization (CSR), clinical signs of hemostasis (CSH), and clinical signs of inflammation (CSI) and were assessed on postoperative days 1, 7, and 14. Mouth opening (determined by measurement of the maximum inter-incisal distance) were assessed just before the surgery and on postoperative days 1, 3, and 7 by using a digital vernier caliper.
