Pre-emptive Single Dose of Intramasseteric Administration of Dexamethasone Versus Methylprednisolone in Surgical Extraction of Impacted Mandibular Third Molars: Prospective Split-Mouth, Randomised Triple Blinded Clinical Study.

Aim: The study aims to contribute in reducing postoperative sequelae and to determine the optimal corticosteroid for reducing postoperative inflammation, pain, swelling, wound healing and quality of life in patients undergoing surgical extraction of impacted mandibular third molars. Materials and Methods: The study included 191 patients who presented to the Department of Oral and Maxillofacial Surgery at Thai Moogambigai Dental College and Hospital in Chennai with bilateral impacted mandibular third molars that needed surgical removal. The effects of pre-emptive single dose of dexamethasone and methylprednisolone on pain, oedema, trismus, wound healing, and quality of life after surgical extraction of impacted lower third molars were investigated. Result: There was no statistical difference between the two steroids, with both achieving identical levels of wound healing and quality of life. On the third postoperative day, there was a statistically significant difference, with methylprednisolone providing clinically superior results in mouth opening and reduction of swelling. However, by the fifth day, both corticosteroids had exhibited identical improvement. Conclusion: Compared to 8 mg of dexamethasone, 40 mg of methylprednisolone administered as a single preemptive dosage in the intrammaseteric region was associated with enhanced quality of life, a reduction in pain and edema, and almost normal mouth opening.
