| 摘 要： | 目的：探讨变形链球菌和远缘链球菌耐氟突变后，其粘附能力的改变。方法用同位素标记方法测定变形链球菌，远缘链球菌亲代及耐氟菌株粘附至唾液包被羟基磷灰石（ＳＨＡ）表面的粘附量及粘附百分率，并比较两者的粘附能力。结果变形链球菌、远缘链球菌亲人菌株与耐菌株间粘附百分率无明显差异（Ｐ〉０．０５）；远缘链球菌与变形链球菌相比，其粘附百分率偏低，差异有显著性（Ｐ〈０．０１）结论变形链球菌与远缘链球菌耐氟菌株粘附至

| Abstract: | Objective To investigate the binding ability of S.mutans and S.sobrinus after their fluoride resistant mutation.Methods The binding amount and binding percentage of S.mutans, S.sobrinus and their F resistant strains to saliva coated hydroxyapatite(SHA)were measured and compared by 3H labeled binding assay.Results The binding percentages of F resistant and their parent strains had few difference( P >0.05),whereas the binding percentage of S.sobrinus was significantly lower than S.mutans( P <0.01). Conclusions The data showed that the binding ability to SHA between F resistant and F sensitive S.mutans had no significant difference which indicated that the emerge of F resistant strains could not reduce the cariogenicity of S.mutans and S.sobrinus. |
