| Abstract: | The state of teeth filled with silver amalgam, silidont, 'evicrol' was clinically assessed in 280 schoolchildren which had been earlier subjects to dental caries prevention. The quality of dental care was assessed by 5 scores developed by the Central Stomatological Institute. One to two years after a combined preventive intervention, the state of filling was found unsatisfactory in 11.0 to 11.3% of amalgam-filled teeth, in 15.8-22.7% of silidont- and 4.3-10.8% of 'evicrol'-filled teeth. The respective values were 18.8-26.3% ; 37.9-39.1%; 14.9-23.9% in control groups. The combined prevention of caries was conductive to improved treatment quality which was accounted for by a 1.5 to 2-fold reduction in the rate of disorders in marginal contact with filling material and secondary caries. The electrometric diagnostic technique was used to evaluate the marginal permeability of filling and to diagnose the caries relapses. The technique allowed detection of the initial stages in the state of filling and concealed secondary caries. |
