Notes:
Literature data was analysed to find the factors which might influence the results of the determination of the dimensional change of dental amalgams during setting, by methods analogous to the test described in ADA Specification no. 1. Included in the paper is a discussion of the different aspects of adaptation of an amalgam restoration to the wall of a cavity. The conclusion was that the ADA dimensional change test is unsatisfactory because its outcome is highly dependent on experimental variables. The experimental problems involved in this test appeared to be unsolvable. A new method to obtain the dimensional change during setting in a clinically relevant way was proposed. This method consists in the determination of the dimensions of preferably cylindrical specimens after setting of the amalgam in a mould.The results are described of the direct determination of the dimensional change by measurement of the diameter of set cylindrical specimens prepared by clinically simulated packing techniques. The dimensional change also was computed from independent measurements of the adaptation. The correlation between the two series of results was determined and compared with the theoretical prediction.A good correlation between both sets of data was established.
