The influence of mixing speed on the setting rate of high-copper amalgams. 1987

W W Brackett, and M L Swartz, and B K Moore, and H E Clark

This study was undertaken to assess the effect of mixing speed on the setting rate of high-copper dental amalgam. The surface hardness during setting of two representative brands of dental amalgam was related to working and carving times determined by clinicians. From this information, a means of evaluating setting rate of amalgam based on surface hardness was developed.
