CHANGE OF MIXED SALIVA ANTIOXIDANT SYSTEM OF CHILDREN AT THE STAGES OF ORTHODONTIC TREATMENT USING THE BASE MATERIALS

Abstract

By means of clinical and laboratory methods the antioxidant system of unstimulated oral fluid is investigated in children aged 4,5 to 8 after the application of removable orthodontic appliances on the indices of diene conjugates, triene conjugates, Schiff bases, as well as the parameters of antioxidant activity. It was revealed that the base units of a photo curable composite «Versyo» due to the minimal growth of values of oxidant and antioxidant activity of mixed saliva without the development of «oxidative stress» provide the lowest possible adaptation periods in comparison with the appliances of the base plastics of hot and cold type of polymerization.
