The aim of this study was to identify factors influencing the selection of restorative materials.
In 1992, a random sample of Finnish dentists working in the public and private health care sectors were asked to provide information on restorative treatments during a given period. The study material consisted of 9886 restorations placed by 855 dentists.
The results indicate that private practitioners sought the opinions of their adult patients regarding the selection of restorative material more frequently (26% of restorative treatments) than their colleagues working in the public sector (11%; P < 0.001). The frequency of resin composite restorations increased and that of amalgam and glass ionomer restorations decreased when the patients' opinions were sought. Forty percent of restorations provided by public dentists and 69% of those completed by private practitioners were replacement restorations (P > 0.001). Secondary caries was the main reason for the replacement of amalgam restorations, whereas fractures of the teeth and restorations were the main reasons for the replacement of resin composite restorations.
The results indicate that patients' opinions have a strong influence on the selection of restorative materials. A large proportion of the restorative treatment studied comprised replacement restorations.
本研究旨在确定影响修复材料选择的因素。
1992年，从芬兰公共和私营医疗保健部门工作的牙医中随机抽取样本，要求他们提供特定时期内修复治疗的相关信息。研究材料包括855名牙医所进行的9886次修复治疗。
结果表明，与在公共部门工作的同事（11%；P<0.001）相比，私人执业牙医在选择修复材料时更频繁地征求成年患者的意见（26%的修复治疗）。当征求患者意见时，树脂复合材料修复的频率增加，汞合金和玻璃离子体修复的频率降低。公立牙医提供的修复治疗中有40%是替换修复，私人执业牙医完成的修复治疗中有69%是替换修复（P>0.001）。继发龋是替换汞合金修复的主要原因，而牙齿和修复体折断是替换树脂复合材料修复的主要原因。
结果表明患者的意见对修复材料的选择有很大影响。所研究的修复治疗中有很大一部分是替换修复。
