Summary. This article investigates the effectiveness and comparative assessment of the effect of gel and rinse aid «Perio-Aid» microflora of periodontal pockets, periodontal tissue and prevention of recurrence of inflammatory processes in the periodontium in young people before orthodontic treatment. It was found that Perio-Aid has more pronounced anti-inflammatory and antimicrobial properties compared to other by means of local therapy. According to the data of clinical and microbiological studies, it has been established that the use of Perio-Aid is already in the tenth day leads to a decrease in the number of periodontal pathogenic microorganisms, eliminates the symptoms of inflammation, reduces the depth of periodontal pockets and has a positive effect on the course of the initial generalized periodontitis, which shortens the preparation time for orthodontic treatment. Key words: periodontium-pathogenic microorganisms, generalized periodontitis.

The aim of this study was to compare the bioactivity of RGO/ceramic oxide-Ag nanocomposites. Different ceramic oxides (MexOy) i.e.: Al2O3, TiO2, SiO2 and ZnO2 were in situ co-deposited with Ag nanoparticles on the surface of RGO resulting in the formation of a nanocomposite structure of stacked flakes. The results of our investigations indicate that it is possible to obtain the targeted biocidal properties of the RGO/Ag system by choosing the appropriate ceramic oxide as a modificator of Ag nanoparticles. The strongest antimicrobial properties against E. coli, S. aureus and Bacillus sp. strains were achieved for RGO/SiO2-Ag nanocomposite whereas for Sarcina sp. bacteria the most effective biocide was RGO/TiO2-Ag nanocomposite.

The research was carried out within the framework of the theme of state assignment № 0593–2019–0008 «To develop theoretical foundations for creating composite mixtures for bakery products using physical methods of exposure that ensure homogeneity, stability of mixtures and bioavailability of nutrients, to optimize diets population of Russia». The data on the species belonging of new strains of lactic acid bacteria and yeast isolated from samples of good quality gluten-free starter cultures are presented. A comparative assessment of the antagonistic and acid-forming activity of strains of lactic acid bacteria and the fermentative activity of yeast was carried out. The composition of microbial compositions from selected strains of LAB and yeast was developed. The influence of the starter culture on the new microbial composition on the physicochemical, organoleptic indicators of the bread quality and resistance to mold and ropy-disease was investigated.
