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.

Introduction. Modern treatment of inflammatory diseases of parodon tissues implies consistency throughout the treatment. Initially, much depends on a high-quality procedure for the removal of dental deposits with further polishing of the tooth root surface. At the moment, doctors use a variety of methods to remove dental deposits in their daily practice. Most authors in their research describe only the advantages and disadvantages of removal of dental deposits, only slipping on the impact of these methods on the condition of hard tissues of the tooth, often these data are contradictory. The purpose of this study is to compare the effectiveness of various occupational oral hygiene methods. Materials and methods. We selected 30 patients suffering from moderate chronic generalized periodontitis between the ages of 20 and 50 to determine the test groups. We used the Cam Scan (REM) raster electron microscope to evaluate the treated surface of the tooth root cement and enamel. We assessed individual oral hygiene level and periodontal tissue condition using hygienic indices such as: OHI-S, API, PHP, hemorrhage index, PI. Results of a research. Objectively, among all patients cyanotic gums and gum edges dominated, mobility is absent, bleeding, loose gum consistency, the presence of paradoxontal pockets and serous-purulent exudate. Practically complete removal of dental deposits from the root cement and in the neck region of the tooth enamel appear during treatment with a UT-scaler, in the area of the tooth neck there are different areas by the degree of roughness. Conclusions. After analyzing the data obtained from our study, we were able to determine the quality of various methods of dental sediment removal and the effect on the microstructure of enamel and cement of tooth root. There is the least effect on the microstructure of the cement of the tooth root by the operation of the scaler, qualitative removal of dental deposits was achieved with minimal influence on the microstructure of the cement of the root and enamel of the tooth.

In this work, we conducted a comparative analysis of various methods of removing dental deposits and the effect on the microstructure of the tooth and the root cement: with the help of a Gracie curette, a magnetostrictive scaler, a piezoelectric device and a Vector device. The material for our study was 40 medically removed teeth. By analyzing the data obtained, we were able to determine both the quality and the effect of various removal methods on the microstructure of enamel and tooth root cement. The smallest influence on the microstructure of the tooth root cement was revealed when working with the Piezon-Master 600 and Vector devices, as well as high-quality removal of ZO was achieved. The effectiveness of therapeutic manipulations was recorded by scanning electron microscopy.
