The aim of our research was evaluation of dynamic of spread of some microbe kinds expansion, which more often inhabit the oral cavity of a healthy person and with dental pathology: caries and gingivitis.
The results of researches revealed that at different dental pathologies the different kinds of microbes predominate: Str. mutans and Staph. epidermicus are typical for caries; Staph. epidermicus, Candida albicans and Enterococus — for chronic catarrhal gingivitis. When dental pathology is absent, Str. viridans and Lactobacillus are more often found.
