Dentists throughout the world continue to use amalgam, a material that their predecessors used, despite the fact that a wide variety of contemporary materials is available. Objectives: The aim of this study was to determine reasons for dentists' choice of materials, in particular amalgam and resin composite. Method: A questionnaire was developed to elicit this information. The names and addresses of 1000 UK-based dentists were selected at random. The questionnaire was mailed to these dentists with an explanatory letter and reply-paid envelope. Results: Six hundred and fifty one replies were received. Ninety nine per cent of respondents considered that clinical indications influenced their choice of restorative materials, while, for 94% of respondents, patients' aesthetic demands influenced their choice. The patient's wish for a certain material and the patient's financial situation influenced the choice of material for 69% and 76% of respondents. Thirty-five per cent of respondents used composite “sometimes”, 15% “often”, and 1% “always” in extensive load-bearing cavities in molar teeth. For composite restorations in posterior teeth, 74% “often” used the total etch technique and 53% never used rubber dam. Seventy per cent of respondents agreed with the statement “discontinuation of amalgam restricts a dentist's ability to adequately treat patients”. Eighty-one per cent considered that the growth in the use of composites increased the total cost of oral health care. Conclusion: It is concluded that 49% of the respondents from Great Britain seldom place large composite restorations in molar teeth and that their choice of material is influenced greatly by clinical indications, and patient's aesthetic demands.
