The aim of this study is to compare the effect on post-surgical oedema after mandibular orthognathic surgery, between two different laser power densities and oral medication with non-steroidal anti-inflammatory.Materials and methodsIn a randomized clinical trial, on 60 patients who were subject to mandibular orthognathic surgery were divided into three groups. All groups received sodium naproxen 250 mg every 8 hours for 6 days. Two groups were irradiated with two different laser application protocols and the other was a control group. In G1 group the irradiation parameters three times per week for two weeks were: 940 nm, in continuous mode, 2.5 W, 120 s, 85.71 J/cm2, 0.89 W/cm2, over the right and left side with a distance from the skin surface of 1 mm with the whitening handpiece (spot size of 2.8 cm2). In G2, the irradiation parameters three times a week for two weeks were: 940 nm, in continuous mode, 4.1 W, 120 s, 68.33 J/cm2, 0.58 W/cm2 over the right and left side with a distance from the skin surface...
