Abstract Postoperative oedema is common following removal of impacted lower third molars. Several types of drug therapy (corticosteroids, non-steroidal anti-inflammatory drugs, enzymes) have been tried. The aim of this study was to compare the effectiveness of low-power laser (LPL) and dexamethasone after surgical removal of impacted lower third molars under local anaesthesia (2\% lidocaine/epinephrine). MATERIAL AND METHODS: There were 120 healthy patients divided into four groups of 30 each. Group 1 received LPL irradiation immediately after operation (energy output 4 J/cm2 with constant power density of 50 mW, wavelength 637 nm); group 2 also received i.m. injection of 4 mg dexamethasone (Dexason) into the internal pterygoid muscle; group 3 received LPL irradiation supplemented by systemic dexamethasone (Dexason), 4 mg i.m. in the deltoid region, followed by 4 mg of dexamethasone intraorally 6h postoperatively; and the fourth (control) group received only the usual postoperative recommendations (cold packs, soft diet, etc.). RESULTS: LPL irradiation with local use of dexamethasone (group 2) resulted in a statistically significant reduction of postoperative oedema in comparison to the other groups. No adverse effects of the procedure or medication were observed. CONCLUSION: LPL irradiation after lower third molar surgery can be recommended to minimize swelling. The effect is enhanced by simultaneous local intramuscular use of dexamethasone. This article was published in Int J Oral Maxillofac Surg and referenced in Family Medicine & Medical Science Research
