COMPARATIVE ANALYSIS OF INDIVIDUAL REPRESENTATIVES OF THE MICROBIOTA OF THE PERIIMPLANT ZONE IN NORMAL AND INFLAMMATORY CONDITIONS

Background:The incidence of periimplantitis has increased significantly in recent years, which has led to an increase
in the number of implant rejection cases and a deterioration in patients’ lives.
The purpose of the study. To conduct a comparative analysis of individual representatives of the microbiota of the
peri-implant sulcus in normal and inflammatory conditions.
Materials and methods: Samples of the contents of the peri-implant sulcus from 20 patients with healthy peri-implant
tissues and 20 patients with peri-implantation. The quantitative and qualitative composition of the microbiota in the
samples was determined by the classical bacteriological method.
Results:It was found that Streptococcus spp., Staphylococcus spp., Candida spp. and Escherichia coli predominate in
the samples obtained from patients of the main group. Moreover, the number of Candida spp. In the main group, the
number of Candida spp is 20.8 times higher. in the comparison group. In addition, representatives of Sarcina spp.,
which had not previously been associated with the development of peri-implantitis, were found.
Conclusion:The microbiota plays a crucial role in the development of peri-implantitis. Further research aimed at
understanding the role of various microorganisms and their mechanisms of action will make it possible to develop
effective strategies for the prevention and treatment of this complex disease. Maintaining good oral hygiene and
regular routine checkups remain key factors in preventing the development of peri-implantitis.
