90 combined gold-amalgam specimens of three dental gold alloys and two amalgams were placed subcutaneously, intraperitoneally and in the cheek pouches of 15 golden hamsters. The appearance of the amalgam surfaces after one week was evaluated using scanning electron microscopy and light microscopy. The results showed that among the implants there was an obvious difference between the conventional amalgam and the non-y2 amalgam specimens as regards accumulation of plaque, which was much more pronounced on the conventional amalgams. The cheek pouch specimens with conventional amalgams differed markedly from the corresponding implant specimens, showing very little plaque accumulation. Some possible explanations for these observations are discussed.
将90个由三种牙科金合金和两种汞合金组成的金汞合金标本皮下、腹腔内以及置于15只金黄仓鼠的颊囊中。一周后，使用扫描电子显微镜和光学显微镜评估汞合金表面的外观。结果显示，在植入物中，传统汞合金和非γ2汞合金标本在菌斑积聚方面存在明显差异，传统汞合金上的菌斑积聚更为明显。带有传统汞合金的颊囊标本与相应的植入标本明显不同，显示出极少的菌斑积聚。讨论了对这些观察结果的一些可能解释。
