To analyse general dentists' choice of restorative materials in Finland, where the use of amalgam has significantly decreased and the use of composites increased during the past 10 years.
Postal survey in 1997 to a random sample of general dental practitioners mainly working with adult patients.
Percentage distribution of dentists' opinions.
The response rate was 82%. Tooth-coloured restorations were considered to be more time consuming, technically complicated and to have shorter life spans. Most dentists were not willing to return to the wide-scale use of amalgam restorations.
The rapid changes in the restorative material selection have not resulted in serious problems in restorative therapy.

1997年对主要诊治成年患者的普通牙科医生进行随机抽样的邮政调查。
牙医意见的百分比分布。
回复率为82%。牙齿颜色的修复体被认为更耗时、技术上更复杂且使用寿命更短。大多数牙医不愿意恢复大规模使用汞合金修复体。
修复材料选择的快速变化并未在修复治疗中导致严重问题。
