[The clinico-immunological characteristics of the course of recurrent aphthous stomatitis].

Clinical and laboratory examinations of 86 patients with relapsing aphthous stomatitis making use of a complex of clinical, immunological, cytochemical, and microbiological methods, helped specify the clinico-anamnestic features in the course of this disease. An immunobacterial concept of the pathogenesis of relapsing aphthous stomatitis has been formulated; according to this concept, the disease is initiated by disorders of T and B immunity system and nonspecific defense factors, leading to increase of the content and virulence of oral microflora, and thus stimulating the bacterial sensitization of the organism of patients with relapsing aphthous stomatitis.
