The frequency of Streptococcus mutans in plaque material from margins of conventional amalgam and non-gamma-2 amalgam fillings was examined in six subjects. One and 2 months after restorative treatment the mean values of the percentage S. mutans of the total number of microorganisms were somewhat lower in samples from non-gamma-2 amalgams than in those from conventional amalgams. The difference in values, however, was not statistically significant.
在六名受试者中检测了传统汞合金和非γ-2汞合金充填体边缘菌斑材料中变形链球菌的频率。修复治疗后1个月和2个月，非γ-2汞合金样本中变形链球菌占微生物总数的百分比平均值略低于传统汞合金样本。然而，这些数值的差异无统计学意义。
