Features of biophysical properties and composition of oral fluid in children with connective tissue dysplasia living in the conditions of high latitudes
Abstract
The article dwells on a comprehensive clinical and laboratory study of children with connective tissue dysplasia (CTD), living in the North. The findings suggest that the presence of certain changes in the composition and properties of the oral fluid, which leads to disruption of the structural homogeneity of hard tissue of teeth and reduce their caries. In the surveyed age groups of children biophysical properties of the oral fluid are characterized by a decrease in secretion rate, increased saliva viscosity, the prevalence of type II and III microcrystallisation, decrease of remineralizing potential of oral fluid. In the composition of saliva there were marked decrease in the total protein concentration in children with severe CTD, alkaline phosphatase activity, regardless of severity, concentrations of magnesium and calcium cations, which are essential in saturation by mineral components of tooth enamel hydroxyapatite.
The revealed features of the composition and properties of oral fluid can be considered as specific regional biological risk factors for the formation of pathological processes of organs and tissues of the oral cavity in children with CTD, living in the North.
