The study of the composition of the microflora of the periapical tissues during exacerbation of chronic periodontitis

The aim of the study was to determine the species composition of microorganisms in the periapical tissues, quantitative and qualitative change their composition during the application of antibiotic therapy in exacerbations of chronic periodontitis. The results of our study showed the prevalence in the studied material anaerobic asporogenic bacteria capable of vehetuvaty in the mouth and in the norm, despite their abstractionist they can become pathogens in microbial association. When antibiotic therapy revealed changes in the composition of the microflora, but the main pathogen remained prevalent in the sample of clinical material. We have found that the quantitative method of study allows to determine the dominant microorganism associations, but is time consuming.
