Microbiological landscape of the periodontal pocket in inflammatory diseases in the periodontal tissues

Relevance. The study of the microbiological composition of periodontal pockets in inflammatory diseases of periodontal tissues is of great importance directly for the effective treatment and understanding of the pathogenetic stages of these diseases. Objective: to study the microbiological landscape of periodontal pockets with inflammatory diseases of periodontal tissues. Materials and Methods. 62 patients aged 20 to 45 years were selected and divided into groups depending on the form of periodontitis: with localized aggressive periodontitis - group №1, group №2 - with chronic generalized periodontitis, group № 3 - with exacerbation of chronic generalized periodontitis. The material for the study was taken from the periodontal pockets and examined by cultural and microbiological methods. Results and Discussion. It was found that the proportion and number of microbial associations in the periodontal pockets of different depths differs. In localized aggressive periodontitis, mainly facultative Gr+ (A. actinomycetemcomitans) and Gr- (St. aureus, Str. mitis) anaerobes were found in the periodontal pockets no more than 4 mm. In generalized chronic periodontitis of moderate degree, the same microorganisms were present in the periodontal pockets as in the localized form, but Str. mitis was more common among facultative aerobes. With the exacerbation of generalized chronic periodontitis from facultative anaerobes, St. aureus was more common and the proportion and number of A. actinomycetemcomitans significantly increased. Conclusion. According to the results of the study, the microorganisms that inhabit the periodontal pockets in inflammatory diseases of periodontal tissues mainly belong to facultative Gr+ and Gr - anaerobes, obligate Gr+ and Gr-anaerobes and yeast fungi.
