Experimental evaluation of the effectiveness of non-pigmented laser photoablation in the treatment of periodontal diseases

INTRODUCTION. High-quality treatment of periodontitis and prevention of further progression of periodontal diseases can be achieved with complex and systematic adherence to algorithms for performing manipulations at all stages of therapy using physical factors. This is possible with the use of laser radiation with the effects of non-pigmented laser photoablation. AIM. Improving the effectiveness of periodontal disease treatment using pigment-free laser photoablation. MATERIALS AND METHODS. An experimental comparative study of 70 animals with model periodontitis under the influence of laser radiation with non-pigmented photoablation, photodynamic laser therapy and standard drug therapy was conducted in 3 groups. Morphological studies were performed for group I (main) and group II (comparison) were withdrawn from the experiment on the 7 th , 14 th and 21 st days of treatment. Animals of group III (control) were withdrawn from the experiment on the 21 st day. RESULTS. Morphological analysis showed that the use of non-pigmented laser photoablation helps to reduce inflammation in periodontal tissues, accelerate regeneration due to stimulation of fibroblast production and stimulation of neoangiogenesis. On the 21 st day of the experiment, in the group using non-pigmented laser photoablation, based on morphological analysis, acceleration of the processes of formation of the periodontal ligament with even bundles of collagen and elastic fibers perpendicular to the tooth root was confirmed. CONCLUSIONS. Our experimental studies confirm the effectiveness of non-pigmented laser photoablation in the treatment of periodontitis.
