The aim of this study was to record any differences in the selection o f materials in private dental practices in Sweden during 1993-95, afte r a ban on amalgam had been proposed by politicians, compared with tho se obtained in a similar survey in 1978-79. A total of 177 clinicians participated in the present survey, which recorded the total number of restorations they placed and the number of composite, amalgam, and gl ass ionomers inserted in the treatment of primary caries and for repla cement of restorations. Furthermore, the number of intact amalgam rest orations replaced by composite and the number and types of inlays and laminates cemented were accounted for. Marked changes in the selection of direct restorative materials were noted in the present study compa red with the survey in 1978-79. Resin-based composite materials are ta king over as the routine posterior restorative material, also in stres s-bearing areas. Glass ionomer restorative materials are used preferen tially in the treatment of primary caries. The use of amalgam restorat ions has decreased in relative and absolute numbers. Mars are infreque ntly used but, when used, usually include three or more surfaces, and ceramic materials predominate.
