Abstract
Purpose. To determine optimal power and exposure characteristics of laser procedures with 1265 nm laser light for treating periodontal diseases in experiment. Materials and methods. 30 Wistar rats were taken into the study. After modeling periodontitis in these animals with the ligature technique, they had laser treatment with 1265 nm quasi-continuous laser light using various power and exposure parameters. The effectiveness of the discussed therapy was assessed on day 7 after the trial beginning. The following objective parameters were analyzed: state of tissues in the oral cavity; morphological picture in periodontal tissues, presence of reactive inflammation and necrotic fragments in the alveolar bone. Results. The obtained findings has demonstrated that the best results were seen in the groups of animals where irradiation parameters were 1.6 W – 300 s and 1.8 W – 180 s. Similarly, morphological picture was also the best in these groups. Conclusion. The most effective and optimal therapeutic regimes are: average power 1.6 W for 300 s (480 J) and 1.8 W for 180 s (324 J).
