Examinations of 18 patients with recurrent aphthous stomatitis, 8 with ulcerative necrotic gingivitis, 10 with lichen planus, 10 with herpetic stomatitis, and of 24 patients without evident clinical symptoms of buccal mucosa involvement but complaining of various stomatogenic sensations, e.g. burning, tightness, pain and pricking in the buccal mucosa, perverted taste, etc., showed that chronic diseases of the buccal mucosa involve expressed shifts in the microbiocenosis, namely, dysbacteriosis of different severity.
