INTERMICROBIAL INTERACTIONS OF THE ORAL BIOTOPE

The article indicates that the oral cavity is one of the complex and stable biotopes, very favorable for the growth and maintenance of the vital activity of microorganisms. However, the biocenoses of all human biotopes are inextricably linked and a change in one of them causes changes in the others. These changes can also lead to negative consequences for the macroorganism. It is known that such common human diseases as tooth decay and inflammatory periodontal diseases are caused by representatives of oral microbiocenosis. These pathologies have their own characteristics and are the result of intermicrobial and organismic relationships. The questions of intermicrobial relations were dealt with by the American ecologist Eugene Odum, who classified biotic relationships by the nature of their influence on interacting species, as well as the Italian mathematician Vito Volterra, considered the founder of the modern mathematical theory of populations. Ukrainian Medical Stomatological Academy employees pay great attention to the study of oral microbiocenosis in normal conditions and in various pathologies. We carried out the calculations of microflora studied in one of these researches according to the V. Volterra formulas and using the modified classification of Yu. Odum. They showed the possibility of determining the type of relationship between associates of the oral biotope. This position may be useful when planning hygienic and therapeutic procedures performed in the oral cavity.
