Objective: to study the qualitative and quantitative composition of microflora in the root canals of teeth in the treatment of patients with chronic apical periodontitis. Material and methods. The efficiency of the treatment of chronic apical periodontitis was determined in two groups of patients: the main group 1 (18 persons) and comparison group 2 (11 persons), by examining culture-biochemical properties of the contents of the teeth root canal (RC), the concentration of total protein and leukocyte. For endodontic treatment in group 1 the «Radent» was used and in group 2 was used «Krezodent.» Results. In group 1 suppression of anaerobic microorganisms was found and the reduce of occurrence of streptococci, the growth of Candida, Enterobacterium and Corynebacterium did not detected. In group 2, rising Candida, pyogenic streptococci, staphylococci and anaerobic microorganisms was found. The concentration of total protein and white blood cells in teeth RC contents in groupl decreased significantly and in group 2 contents did not change. Conclusion. The pathological process in the periodontium under chronic apical periodontitis supported predominantly coccal and anaerobic microflora, with exacerbation prevail streptococci, Neisseria and enterobacteria. Inflammation of the periodont supports leukocyte cells that synthesize the protein molecules. «Radent» has a strong antibacterial and anti-inflammatory effect.
