Release of mercury and copper in water over time from in vivo annealed amalgams in an unpolished and polished state was measured. Mercury and copper loss from unpolished amalgams was on the average 1,00 micrograms/cm2.d and 0.06 micrograms/cm2.d, respectively. Polishing the amalgams reduced these values significantly to 0.19 micrograms/cm2.d for mercury (p = 0.004) and to 0.03 micrograms/cm2.d for copper (p = 0.009). It was concluded that polishing amalgam surfaces (under water cooling) reduces release of mercury and copper significantly.
测量了体内退火后的汞合金在未抛光和抛光状态下随时间在水中汞和铜的释放情况。未抛光汞合金的汞和铜损失平均分别为1.00微克/平方厘米·天和0.06微克/平方厘米·天。对汞合金进行抛光可将这些值显著降低，汞降至0.19微克/平方厘米·天（p = 0.004），铜降至0.03微克/平方厘米·天（p = 0.009）。得出的结论是，（在水冷条件下）对汞合金表面进行抛光可显著减少汞和铜的释放。
