Abstract
Relevance of the study. Among the pathologies of the periodontal system, inflammatory diseases of the periodontal tissue are widespread. According to the World Health Organization, gingivitis and periodontitis occur in 64-98% of the population aged 35 to 44 years. In addition, dysbacteriosis can be observed, which is a change in the microflora of the oral cavity, with an increase in pathogenic and conditionally pathogenic microorganisms. It has been found that during orthodontic treatment, the composition of the microflora of the oral cavity changes, and an increase in the number of Streptococcus mutans, Candida albicans, Lactobacillus spp., Enterobacteriaceae leads to dental caries and inflammatory diseases of the periodontal tissue. Several factors contribute to the course of periodontal diseases, which reduce the reactivity of the body and lead to a decrease in secondary immunity. Modern views have proven that the main role in the etiopathogenesis of periodontal diseases is played by a decrease in the immune system and the resistance of the periodontal tissue to bacteria.
