The purpose of this study was to evaluate the effectiveness of orthodontic treatment with the introduction of a diode laser device, modified according to the intensity of laser. Research methods. The study included 43 patients aged 22-42 years old (29,4±5,83 years) with the displacement of first premolars and their hypersensitivity. Group 1 (n=23) consisted of patients who used standard anti-inflammatory therapy with ibuprofen 200 mg 2 times per day. Group 2 consisted of 20 patients who used laser therapy with the own modified diode laser device (“Laser device for the usage in dentistry for orthodontic treatment”) with the wave of 810 nm. Clinical examination of patients was performed according to the standard protocol. Pain sensation was analyzed by visual analog scale (VAS). The PMA index (papillary-marginal-alveolar) proposed by Masser and the PFRI index for quantifying the rate of dental plaque formation. Research results. It was found that the assessment of pain sensitivity for VAS was 7,9±3,9 and 8,3±4,1 points in the observation groups. At the end of the course – 2,2±0,9 (reduction VAS in 2,59 times) versus 1,9±0,7 points (reduction in 3,37 times). Also, the influence on the temperature sensitivity was more effective in diode laser therapy. After analysis of absolute effectiveness, 73,9% (17,0 people) showed the reduction of pain temperature sensitivity after laser therapy versus 40,0% (8,0 people) of absolute effectiveness after anti-inflammatory therapy with the reliable relative efficacy and odds ratio. It was proved the reliable decrease of the PMA index in both groups (from 26,3±6,8 to 8,2±1,91 in group 1, p<0,05) and from 24,8±5,9 to 14,2±3,51 (p<0,05) in group 2). At the same time, the level of the PMA index reduction in the group of laser therapy was significantly higher (p1<0,05). The hygienic state according to the PFRI index decreased in both groups (p<0,05), with the reliable additional reduction (9,1±3,4 versus 18,9±4,9, that is 9,8 points) in the group where laser therapy was used. We have evaluated the reliable probability of side effects in patients who were prescribed standard drug therapy with ibuprofen against group 2, which used the “Laser device for usage in dentistry for orthodontic treatment”. So, the discomfort in the epigastrium was indicated in 4 patients from group 1, where ibuprofen (AR – 10,0%) was prescribed and none of the patient in group 2, where the therapy with diode laser therapy was performed. The number of patients with elevated alanine aminotransferase levels were also identified for the appointment of ibuprofen (10,0%, 2,0 persons), although there was no side effect in group 2. That is, in assessing the common tolerability of ibuprofen and diode laser therapy, it was 71,0% versus 100,0%.
