The purpose of the present work was to study the setting of amalgams made from several different commercial alloys by recording the rate of initial mercury consumption, and then to compare the findings with those from other methods of defining the early setting process. The results show that the rate of initial mercury consumption is well correlated with clinicians' classification of the rate of setting of amalgams, but not correlated with mechanical tests like early compressive strength and guillotine setting time used till now in estimating the working time of amalgams. Based on these findings an appropriate method of determining the mercury:alloy proportion and working time of dental amalgams is suggested.
本研究的目的是通过记录初始汞消耗率来研究由几种不同商业合金制成的汞合金的凝固情况,然后将研究结果与其他定义早期凝固过程的方法所得结果进行比较。结果表明,初始汞消耗率与临床医生对汞合金凝固速率的分类密切相关,但与目前用于估计汞合金工作时间的早期抗压强度和断头台凝固时间等机械测试无关。基于这些发现,提出了一种确定牙科汞合金汞与合金比例及工作时间的合适方法。
