USE OF INTEGRAL INDICES IN THE ASSESSMENT OF BUCСAL CYTOLOGY IN HEALTH AND IN THE ORAL CAVITY PATHOLOGY

: Cytological analysis of buccal epithelium (BE) - the buccal cytogram allows to select about 20 parameters reflecting cytogenetic, inflammatory, proliferative and other disorders in epithelial cells used for biomonitoring and laboratory diagnostics. In order to simplify and increase the information content of this study, we conducted a comparative analysis of various integral indices when interpreting the buccal cytogram. 40 practically healthy volunteers, 35 patients with chronic periodontitis, 22 patients with chronic gingivitis and 20 patients with partial loss of teeth were examined. The obtained data revealed an increase in the degree of disorders of proliferation and apoptosis, their ratio as the inflammation increased from gingival tissue lesions to inflammation periodontal tissue. In assessing the condition of the mucous membranes in chronic gingivitis, the apoptosis index turned out to be more informative.In chronic periodontitis the index of cytogenetic disorders is indicative. In this category of patients, the accumulation index of cytogenetic disorders did not have any advantages over the others, and the reparative index was less informative.
