Abstract
In Dagestan, mean value of daytime summer temperature in open areas was 27,4 °С (maximum – 30,0 °С), relative humidity – 77,3 % (up to 100,0 %), wind velocity – 4,3 (up to 7,0) m/s. Wind cooling index confirmed a decrease of loss of heat by organism due to convection up to 21,8 %. The heat exchange of organism by evaporation was hampered due to high humidity. It led to disturbances in mineral balance of organism: a decrease of levels of potassium, sodium and chlorine. The ratio calcium: phosphorus was disturbed due to a decrease of calcium in 53,3 % and an increase of phosphorus in 86,7 % of adults, respectively. The stomatological status was characterized by shift of saliva pH to acid, mineralization potential to demineralization, decrease of salivation and enamel resistance to acid; it led to elevated risk of caries of dental solid tissues.
