Restored teeth were extracted from test animals at four time intervals (1 hour, 1 day, 1 week, and 3 months) following amalgam insertion. Extracted teeth were frozen in liquid nitrogen, cryo-fractured so as to expose the pulps and then freeze-dried. Pulps were analyzed for mercury content by energy dispersive spectrometry (EDS) and atomic absorption spectrophotometry (AAS). Mercury levels appeared below the detection limits of EDS but could be detected by AAS which showed the highest readings seven days after amalgam insertion.
在银汞合金充填后的四个时间点（1小时、1天、1周和3个月）从实验动物口中拔除修复牙。将拔除的牙齿在液氮中冷冻，进行冷冻断裂以暴露牙髓，然后冻干。通过能量色散光谱法（EDS）和原子吸收光谱法（AAS）分析牙髓中的汞含量。汞含量在EDS的检测限以下，但可以通过AAS检测到，AAS显示在银汞合金充填后七天读数最高。
