本体外研究对覆盖S-PRG树脂块表面的唾液涂层中吸收的离子进行了元素分析，并评估了血链球菌和变形链球菌对这些唾液涂层S-PRG树脂块的粘附性。采用电感耦合等离子体原子发射光谱仪和氟电极法对暴露于唾液的树脂块的唾液膜中吸收的离子进行元素分析。测定放射性标记的测试细菌对树脂块的定量粘附。作为结果，涂有唾液的S-PRG树脂显示出比涂有唾液的未填充树脂显著更大量的吸收B、Al、Si、Sr和F。特别是S-PRG树脂的唾液涂层降低了S.这种树脂的变异。然而，在S.在sanguinis中，唾液涂覆的S-PRG树脂和唾液涂覆的未填充树脂之间的粘附性没有显著差异。
This in vitro study performed elemental analysis of the ions absorbed into the salivary coat covering the surfaces of S-PRG resin blocks and assessed the adherence of Streptococcus sanguinis and Streptococcus mutans to these saliva-coated S-PRG resin blocks. Elemental analysis of ions absorbed into the salivary coat of resin blocks exposed to the saliva was performed using an inductive coupled plasma atomic emission spectrometer and the fluoride electrode method. Quantitative adherence of radio-labeled test bacteria to the resin blocks was determined. As the results, the saliva-coated S-PRG resin showed significantly greater amounts of absorbed B, Al, Si, Sr, and F than the saliva-coated unfilled resin. It was of particular significance that the salivary coating of the S-PRG resin reduced the adherence of S. mutans to this resin. However, in the case of S. sanguinis, no significant difference in adherence could be recognized between saliva-coated S-PRG resin and saliva-coated unfilled resin.
