Evaluation of Corticosteroid Administration Following Impacted Third Molar Surgery Using 3-Dimensional Facial Analysis
Sponsor: Irfan Üstündağ
Summary
The purpose of this prospective, randomized, controlled, single-blind clinical trial is to compare the efficacy of local submucosal administration of dexamethasone versus methylprednisolone on postoperative morbidity following impacted lower third molar surgery. The study evaluates postoperative pain using the Visual Analog Scale (VAS) and quantifies three-dimensional facial edema using a mobile smartphone-based scanning workflow (Qlone aligned in CloudCompare). Patients requiring unilateral extraction of fully bone-impacted mandibular third molars are randomly allocated into three parallel groups: Control (no injection), Methylprednisolone (40 mg), and Dexamethasone (8 mg).

Surgical Extraction of Impacted Mandibular Third Molar
All patients in the study undergo a standardized surgical removal of a fully bone-impacted lower third molar performed by a single experienced surgeon. Under general anesthesia, a triangular flap is elevated, followed by conservative osteotomy and tooth division using rotary instruments under continuous sterile saline irrigation. After tooth delivery, the socket is thoroughly debrided, irrigated, and closed primarily using 3-0 silk sutures.
methylprednisolone sodium succinate
Immediately following the completion of the tooth extraction and before structural flap closure, a single local dose of 40 mg methylprednisolone sodium succinate is administered. The lyophilized powder is reconstituted with its commercial solvent to a final volume of 2 mL and injected slowly into the adjacent submucosal mucobuccal fold.
Dexamethasone Sodium Phosphate Injection
Immediately following the completion of the tooth extraction and before structural flap closure, a single local dose of 8 mg/2 mL dexamethasone sodium phosphate is administered. The ready-to-use commercial solution is injected slowly directly into the adjacent submucosal mucobuccal fold.
