Permanent Representatives Microflora of the mouth - the most informative indicator of the state as an organism as a whole, and oral cavity. In the mouth a person contains the largest number of species of bacteria compared with other cavities. According to different authors, the number of bacterial species varies from 100 to 300. This is explained by the presence in the oral cavity as a "transient" microorganisms, and a constant bacterial flora. So-called "transit" microorganisms fall into the mouth with air, water, food and their stay is limited. Continuous oral microflora forms a complex and stable ecological system. Others who may share this opinion include BP. Under normal circumstances, when a person does not use antiseptics, antibiotics and other drugs, changes in the existing ecosystem occurs only in a qualitative representation of one or more species. Species of microorganisms remains at a particular individual is almost constant throughout life. The state of the microflora of the mouth affects the morphology of the oral cavity, the composition of saliva and the rate of its formation, the nature of food availability bad habits, heredity, and the decisive factor is the saliva. Besides saliva, micro-organisms found in dental plaque, sulcus and on the back of the tongue (especially in the posterior third). According to different authors, number of bacteria in saliva is an average of 750 million in 1 ml. The concentration of bacteria in dental plaque and gingival groove is almost 100 times higher, about 200 billion cells in 1 g sample. Half of the Permanent Representatives of the microflora mouth are optional and obligate anaerobic streptococci, which include in its membership Str.mitis, Str.mutans, Str.sanguis, as well as peptostreptokokkami.
