This study aim to assess the efficacy of a MLS^® Mphi therapeutic laser as an adjunct management of postoperative pain, swelling, and trismus related the surgical extraction of impacted third molars using visual analogue scale (VAS) and satisfaction outcome measure. A cohort of 42 impacted wisdom patients, each underwent surgical extraction of 4 extractions under local anesthetic, were selected for a double-blind, randomized, controlled clinical trial. The two groups of patients were divided into control and study group, each of 21 patients, match my age and sex. Immediately after the extraction procedure, the experimental group received one off 1.27 J/cm2 of energy density intraorally using Mphi laser while the control, group received sham radiation. The degree of postoperative pain, swelling, trismus, and dry socket was registered for both groups at day one, day 7 (one week) and day 28 (4 weeks). Only those normal patients with 4 impacted wisdom teeth required flap approach, and had complete clinical data were included in this study. Using visual analogue scale (VAS = 0 to 10), the study group revealed to have less: pain, swelling, bleeding and speech impairment and had better overall satisfaction at one day and one week than the control counterpart (*P<0.05). No significant difference in pain at 1 months. The study group showed a less dry socket than the control group without statistical significance. All participants in the both groups required analgesics, however, the study group required less pain killer than the control group between day one to day seven. At one week, the study group had less moderate trismus and more mild trismus compare to the control group (P<0.05). The application of ASA Mphi laser in the postoperative management of pain in surgical wisdom teeth extraction statistically produced early stage of satisfaction as well as reduced postoperative pain, swelling, bleeding, speech impairment, analgesics use and trismus.
