Orthodontic structures due to the complexity of the device, changes in the properties of saliva contribute to the creation of favorable conditions for the growth of microbial biofilm and the development of inflammatory periodontal diseases. In the course of the work, the initial hygiene index of the studied groups was established. The microbial landscape of the surfaces of the teeth of the oral cavity was represented by polymicrobial flora (bacteria and microscopic fungi). After professional oral hygiene, a decrease in the number of inoculated species was observed in 83% of cases and in 60%, the diversity of microflora decreased by more than 4 times. However, already two months after the procedure, the quantitative composition of microflora increased more than twice, and by the 6th month of the study in the group with orthodontic structures, the microbiological indicators exceeded the initial ones.
