This preliminary report is based on a survey of the reasons for inserting 790 glass-ionomer cement, 2,609 resin composite, and 898 amalgam restorations in adults in general practice. Glass-ionomer materials were used about equally for the treatment of primary caries and for replacement of failed restorations, unlike resin composite and amalgam, which were most often used to replace failed restorations. Almost half of the 412 replaced glass-ionomer cement restorations were removed because of the clinical diagnosis of secondary (recurrent) caries, which was by far the most common reason for replacement of all three materials.
这份初步报告基于一项针对在普通医疗中为成年人植入790颗玻璃离子水门汀、2609颗树脂复合材料和898颗汞合金修复体的原因的调查。与树脂复合材料和汞合金不同，玻璃离子材料在治疗原发性龋齿和替换失败修复体方面的使用频率大致相同，树脂复合材料和汞合金最常用于替换失败的修复体。在412颗被替换的玻璃离子水门汀修复体中，近一半是由于临床诊断为继发（复发性）龋齿而被移除的，这是所有三种材料被替换的最常见原因。
