In this study, we recorded the type of restoration and the materials used in 24,429 restorations in permanent teeth by 243 Norwegian clinicians in general practice. Demographic information included patient's gender and age, and clinician's gender, years since graduation, and practice setting (private or salaried). The overall recorded use of restorative materials in permanent teeth shows that 32% are amalgams, just over 40% composites, and about 25% glass ionomer type materials. Three percent are "other" materials. A marked shift away from amalgam restorations is noted both in the clinician's estimated use during the last 2 decades and by comparing the present use of materials with that in failed restorations. Tooth-colored materials are more commonly used in adolescents, especially glass ionomer materials, and in female patients. In patients < or = 18 years, amalgam is used in 25% of all restorations. The use of amalgam is similar in private practice and in public health service practice, but private practitioners use more composites and salaried dentists more glass ionomers. The clinician's gender does not have any effect on the selection of restorative materials. The change from amalgam to tooth-colored material is particularly noticeable for Class I and Class V restorations. Amalgam is the predominant material in 2- and 3-surface Class II restorations.
在本研究中，我们记录了挪威243名全科临床医生在恒牙中进行的24429次修复的修复类型和所用材料。人口统计学信息包括患者的性别和年龄，以及临床医生的性别、毕业年限和执业环境（私人执业或受薪执业）。恒牙修复材料的总体记录使用情况表明，32%为汞合金，略高于40%为复合树脂，约25%为玻璃离子类材料。3%为“其他”材料。无论是临床医生对过去20年使用情况的估计，还是将目前材料的使用情况与失败修复中的使用情况进行比较，都可以注意到明显远离汞合金修复的趋势。牙齿颜色的材料在青少年中更常用，尤其是玻璃离子材料，在女性患者中也是如此。在18岁及以下的患者中，25%的修复使用汞合金。汞合金在私人执业和公共卫生服务执业中的使用情况相似，但私人执业者使用更多的复合树脂，受薪牙医使用更多的玻璃离子材料。临床医生的性别对修复材料的选择没有任何影响。从汞合金到牙齿颜色材料的转变在I类和V类修复中尤为明显。汞合金是双面和三面II类修复中的主要材料。
