On 103 randomly chosen patients composite-, amalgam-, and cast gold fillings were checked and examined after various criteria. Also, the gingival changes were noted and vitality tests made. As was to be expected, composites, particularly class 2-fillings, showed more loss of substance than amalgams. The latter, however, had a worsening marginal adaptation with increasing age. Secondary caries was generally more frequent in subgingival fillings. The quality of the material was of smaller importance than the marginal leakage. Inflammatory processes of the gingiva were more frequent with composites than with inlays. Gradually increasing discolorations were the rule. Very few teeth lost their vitality after treatment, irrespective of the bases (normal, direct and indirect capping).
对103例随机选取的患者，根据不同标准对复合树脂充填物、汞合金充填物和铸造金充填物进行了检查。同时，记录牙龈变化并进行活力测试。正如预期的那样，复合树脂，尤其是Ⅱ类洞充填物，比汞合金充填物有更多的物质损耗。然而，汞合金充填物的边缘适应性会随着年龄增长而变差。龈下充填物中继发龋通常更常见。材料质量的重要性低于边缘渗漏。与嵌体相比，复合树脂充填物导致牙龈炎症的情况更常见。变色通常会逐渐加重。无论使用何种垫底材料（普通垫底、直接盖髓和间接盖髓），治疗后很少有牙齿失去活力。
