Quality of orthopedic rehabilitation of patients with post-traumatic defects of the upper jaw by characteristics of biocenosis of the oral cavity

Abstract

The aim of the research was to study the dynamics of the microbiota's features of oral mucosal membrane during orthopedic rehabilitation of patients with removable dentures which has an obturating part with two-layer bases. Materials and methods: To achieve this goal, our bacteriological examination of oral cavity mucosa was performed for 25 patients with partial adentia of the upper jaw and defect of hard palate and alveolar process. Results and conclusions: Of the conducted studies indicate significant shifts in the qualitative and quantitative composition of microbiocenosis in the oral cavity in patients with partial adenia of the upper jaw and a defect of hard palate and alveolar process due to representatives of moraksel, enterobacteria (representatives of the kinds Klebsiella and E. coll). The comparing of frequency of extraction and the density of microbial colonization showed us the persistence in biotope of representatives near 13 kinds of bacteria and yeast-like fungi of the kind Candida in averages from lg (2,5 ± 0,19) to lg (5,4 ± 0,17) CFU/g. For patients who have been made a two-layered basis, materials of which are based on carboxymethylcellulose and polyvinialacetate in the period of adaptation to removable dentures, showed us that the detection of 5 component associations at 30 days was reduced by 2 times (x2 = 5,991; v = 2; p <0,05) . The frequency of removal and density of microbial colonization of the experimental group did not differ statistically. Among patients in the control group, the microbial colonization density increased for Enterococcus spp, for Klebsiella spp and for Candida spp. Yeast-like fungi. A significant decrease in the microbial density of the resident microflora was 1.4 times for Neisseria spp, 1.6 times for Lactobacillus spp (p <0,05).
