Comparative Study of the Efficacy of Low-Level Laser Therapy and Dexamethasone in Reducing the Severity of Post-Operative Inflammatory Response Following Surgical Extraction of Mandibular Third Molars.

Objectives: To assesses the efficacy of low-level laser therapy (LLLT) over dexamethasone in reducing postoperative edema and trismus following surgical removal of mandibular third molars.

Study Design: A single-center, parallel group, randomized, prospective, single-blind clinical trial on 50 patients between the age 18-40 years, requiring surgical extraction of mandibular third molars classified as mesioangular, class II and position B impactions, was selected for the study. The selected patients were randomly divided into two groups: , Soft Tissue Diode laser was applied intra-orally and extra-orally at the insertion of the masseter.
