title: [The dynamics of changes in rheological properties of oral fluid in patients with different levels of oral hygiene, using removable dentures].
abstract: The issue of changing the physical and physico-chemical characteristics of oral fluid and their dependence on the level of oral hygiene in patients with removable dentures, requires further study. Therefore, in 86 individuals with 138 removable dentures, and 34 patients who are dentally and somatically healthy, we have had studied the parameters of viscosity, velocity of salivation, pH and concentration of mucin. According to the results of the factor analysis, it was determined that 78.6% of the studied parameters were indicators of hygienic condition of oral cavity. On the basis of significant difference and the strength and direction of correlation between the studied parameters and values of the integral index of oral hygiene, it was found, that in patients without somatic pathology with proper oral hygiene, we observed the growth of the rate of salivation and pH(c1), and in case of improper hygienic condition - reducing rate of salivation and increasing concentration of mucin. In case of the presence of somatic pathology, with an improvement of oral hygiene, the growth of pH(c1) and reducing of concentration of mucin was observed. The deterioration of oral hygiene level led to the increase of the rate of viscosity and the reduction of the salivation rate.
