Almost every patient who seeks help from medical institutions is faced with diseases of the dentoalveolar system. It is for this reason that this problem draws the attention of dentists of various specializations.

Microbial biodiversity makes a significant contribution to the development of inflammatory diseases of periodontal tissues from the side of the modern model of periodontitis development. The fine quantitative and qualitative line between the normal oropharyngeal flora and periodontal pathogens largely determines the further pattern of the pathological process development.

The emergence of MALDI-ToF mass spectrometry in modern microbiology has significantly increased the importance and necessity of isolating microorganisms on nutrient media, due to the rather low cost of studying one sample.

In this regard, the purpose of our study was to conduct microbiological diagnostics and analysis of the microbial diversity of periodontal pockets in patients with chronic periodontitis to determine the dominant groups of various periodontopathogens.
