METHODS AND METHODOLOGIES

Scentific article

The paper attempts to analyze methods for assessing the risk of caries based on the quantitative assessment of cariogenic microorganisms through the prism of microbiological studies carried out on the basis of UMSA (Poltava). The greatest role in the initiation of caries was determined in microorganisms that are active against the formation of acids and the polysaccharides produced by them, which have adhesive properties – streptococci, lactobacilli and actinomycetes. Some researchers include Candida mushrooms in this series. Therefore, in the arsenal of a modern dentist, in addition to methods for studying saliva, buffer capacity, secretion rate and pH of saliva in the dental office, methods have also appeared that allow us to estimate the number of cariogenic microorganisms – Streptococcus mutans and Lactobacillus. In addition, under such tests, individual programs for the prevention of caries have been compiled.The UMSA employees conducted a study of the microbiocenosis of the oral cavity in young people with different intensities of caries. We studied the percentage and quantitative microflora of the oral biotope in individuals with different KPI indices. His results showed that with an increase in the intensity of caries, a change in the balance in the composition of the microflora of the oral cavity occurs. Actinomycetes and fungi of the genus Candida have the largest dynamics of increase in the number, and lactobacilli and streptococci multiply rather slowly with an increase in CPU. This indicates a large functional activity of actinomycetes and fungi. It follows that tests reflecting the number of representatives of microbiocenosis are not objective enough. More objective should be tests that reflect the indicators of the function of representatives of the microbiota.
