EVALUATION OF THE EFFECTIVENESS OF LOW-LEVEL LASER THERAPY IN CONTROLLING PAIN, SWELLING, AND TRISMUS FOLLOWING SURGICAL REMOVAL OF IMPACTED MANDIBULAR THIRD MOLARS AT BINH DUONG GENERAL HOSPITAL
Main Article Content
Abstract
Introduction: Low-Level Laser Therapy (LLLT) has been reported to be effective in reducing postoperative symptoms. This study aimed to evaluate the effectiveness of intraoral and extraoral LLLT in controlling pain, facial swelling, and limited mouth opening following the surgical removal of impacted mandibular third molars. Methods: A controlled clinical study was conducted on 51 patients at Binh Duong General Hospital between February and July 2023. Participants were randomly assigned into three groups: intraoral LLLT, extraoral LLLT, and a control group. Pain intensity, facial swelling, and maximal mouth opening were assessed on postoperative days 1, 2, 3, and 7. Results: On postoperative days 1 and 2, the intraoral LLLT group experienced significantly less pain compared to the other two groups. Both LLLT groups showed a reduction in facial swelling, with intraoral LLLT being the most effective in reducing horizontal swelling. Extraoral LLLT was associated with a greater improvement in maximal mouth opening. Conclusion: Low-level laser therapy applied postoperatively is effective in reducing pain and swelling, as well as improving mouth opening on days 1 and 2 following the surgical removal of impacted mandibular third molars.
