Synthetic hydroxyapatite and human dental enamel (polished and non-polished) were subjected to various fluoride applications, i.e., using solutions of sodium fluoride (NaF), acidulated phosphate fluoride (APF), and stannous fluoride (SnF2). Treatment with APF has a strong influence on the morphology of the apatite. All fluorides, in particular SnF2, make the enamel surfaces more hydrophobic. NaF and APF applications slightly alter the electrokinetic potentials of the surfaces, but SnF2 renders them much more negatively charged. The adsorption of the proteins lysozyme and alpha-lactalbumin on these surfaces can be explained in terms of electrostatic and hydrophobic interactions between the proteins and the sorbent surfaces.
合成羟基磷灰石和人类牙釉质（抛光和未抛光）接受了各种氟化物处理，即使用氟化钠（NaF）、酸性磷酸氟（APF）和氟化亚锡（SnF₂）溶液。用APF处理对磷灰石的形态有很大影响。所有氟化物，特别是SnF₂，使牙釉质表面更疏水。应用NaF和APF会轻微改变表面的电动电位，但SnF₂会使其带更多负电荷。蛋白质溶菌酶和α-乳白蛋白在这些表面上的吸附可以根据蛋白质与吸附剂表面之间的静电和疏水相互作用来解释。
