对9种市售银汞合金进行了体外抗菌性能测试。对唾液细菌进行杀菌试验，对变形链球菌OMZ 176进行生长抑制试验，对变形链球菌进行时间依赖性杀菌试验。所有银汞合金都表现出一定的抗菌性能。分散合金和Rvalloy在所有试验中都有很强的抗菌力；ANA 2000和Sybraloy对变形链球菌有杀灭作用，但在唾液试验和生长抑制试验中效果较差。铜汞合金Neo-Silbrin和Cupromuc在唾液试验中活性最高，但在生长曲线试验中抑制作用较小。在唾液杀菌试验中，斯博罗伊、伊迪罗伊和阿马尔卡普表现出中等活性，但在生长抑制研究中相对较弱。生长抑制研究中对培养液中汞、银和铜的分析表明，铜汞合金释放出汞，特别是从Rvalloy；Indioy释放出银，而Neo-Silbrin、Cupromuc、Sybraloy和ANA 2000释放出比其他品牌更多的铜。
Nine commercial dental amalgams were tested for antibacterial properties in vitro. A bactericidal test on salivary bacteria, a growth inhibition test on Streptococcus mutans OMZ 176, and a time-dependent bactericidal test on S. mutans were used. All amalgams displayed some antibacterial properties. Dispersalloy and Revalloy were strongly antibacterial in all tests; ANA 2000 and Sybraloy killed S. mutans but were less potent in the salivary test and in the growth inhibition experiments. The copper amalgams, Neo-Silbrin and Cupromuc, were the most active in the salivary test but less inhibitory in the growth curve experiments. Spheraloy, Indiloy, and Amalcap showed intermediate activity in the salivary bactericidal test but were relatively weak in the growth inhibition studies. Analysis of Hg, Ag, and Cu in media from the growth inhibition studies showed release of Hg from the copper amalgams and, particularly, from Revalloy; Indiloy gave off Ag, whereas Neo-Silbrin, Cupromuc, Sybraloy, and ANA 2000 released more Cu than the other brands.
