In order to obtain information from practising dentists in Finland about their experiences of and attitudes to dental restorative materials, a cross-sectional survey was conducted in spring 1990 using a postal questionnaire. The response rate was 73% (454 replies). Virtually all (99%) respondents had faced questions about the safety of dental materials in 1989 and 93% of all questions concerned amalgam. Most respondents assessed their theoretical knowledge and practical experience of amalgam, composite and glass ionomer as good, whereas gold and ceramics as filling materials were less familiar. However, the three latter materials were regarded as safe by most respondents. Composite was believed to pose the highest risk of side-effects. Although few dentists regarded amalgam as hazardous, it was estimated that the use of this material will decrease over the next five years in favour of glass ionomer, ceramic materials and composite. Changing dental fillings at the patient's request without odontological indications was opposed by about 80% of the dentists, even if patients were to bear the total cost themselves. Only 7% of the dentists claimed to be worried about the possible risks to themselves of handling amalgam at work, and 97% reported having amalgam fillings personally.
为了获取芬兰执业牙医对牙科修复材料的使用经验和态度方面的信息，1990年春季通过邮政问卷进行了一项横断面调查。回复率为73%（共收到454份回复）。几乎所有（99%）的受访者在1989年都遇到过关于牙科材料安全性的问题，其中93%的问题涉及汞合金。大多数受访者认为自己对汞合金、复合树脂和玻璃离子体的理论知识和实践经验良好，而对金和陶瓷作为填充材料则不太熟悉。然而，大多数受访者认为后三种材料是安全的。复合树脂被认为产生副作用的风险最高。尽管很少有牙医认为汞合金有危害，但据估计，在未来五年内，这种材料的使用将会减少，转而青睐玻璃离子体、陶瓷材料和复合树脂。即使患者自己承担全部费用，约80%的牙医反对在没有牙科学指征的情况下应患者要求更换补牙材料。只有7%的牙医声称担心在工作中处理汞合金可能给自己带来风险，97%的牙医报告称自己有汞合金补牙。
