Tannerella forsythia as one of severity degree predictors for chronic generalized periodontitis

BACKGROUND: Chronic generalized periodontitis takes the second place by the occurrence rate worldwide among the diseases of the maxillofacial area. High significance of preventing and early diagnostics for chronic generalized periodontitis is defined by the early tooth loss, by the decrease in chewing efficiency and by the development of chronic infection foci. It is known that the main etiology factor of chronic periodontitis is the microbial one, including the representative of the oral cavity microbiota - Tannerella forsythia, which is a Gram-negative, anaerobic bacterium.
