The adherence of Streptococcus sanguis ATCC 10556, S. sanguis ATCC 10557, S. mutans Ingbritt, and S. mutans OMZ 176 to the surfaces of composite resins, amalgam alloys, and a Au-Ag-Pd alloy was measured. Adhesion was correlated with values for hydrophobicity and zeta-potential of the bacteria and the restorative materials. The hydrophobicity of the restoratives showed a positive correlation between the numbers of adherent S. sanguis cells, suggesting that hydrophobic interactions are important for the adherence of this bacterial species. In contrast, the numbers of adherent S. mutans cells showed a positive correlation with the zeta-potential of the restoratives, suggesting that electrostatic interactions are important in adherence of this bacterium.
测定了血链球菌ATCC 10556、血链球菌ATCC 10557、变形链球菌Ingbritt和变形链球菌OMZ 176对复合树脂、汞合金和金-银-钯合金表面的黏附情况。黏附与细菌及修复材料的疏水性和ζ电位值相关。修复材料的疏水性与黏附的血链球菌细胞数量呈正相关，这表明疏水相互作用对于该细菌物种的黏附很重要。相比之下，黏附的变形链球菌细胞数量与修复材料的ζ电位呈正相关，这表明静电相互作用在该细菌的黏附中很重要。
