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.
对280名曾接受过龋齿预防的学童的牙齿填充银汞合金、硅酮材料、“evicrol”后的状况进行了临床评估。牙科护理质量由中央口腔医学研究所制定的5个评分标准进行评估。在联合预防干预一到两年后，发现银汞合金填充牙中有11.0%至11.3%、硅酮材料填充牙中有15.8%至22.7%、“evicrol”填充牙中有4.3%至10.8%的填充状况不令人满意。对照组的相应数值分别为18.8%至26.3%、37.9%至39.1%、14.9%至23.9%。龋齿的联合预防有助于提高治疗质量，这是由于与填充材料边缘接触紊乱和继发龋齿的发生率降低了1.5至2倍。采用电测诊断技术评估填充物的边缘渗透性并诊断龋齿复发情况。该技术能够检测到填充状态的初始阶段和隐匿性继发龋齿。
