项目摘要

When fluoride with high solubility in water was added into resinous materials, the materials could release large amount of fluoride. However, all of fluoride source was consumed in early stage and the materials finish to release fluoride ion soon. Therefore, the coating of the fluoride with hydrophobic film may prohibit somewhat the contact of fluoride with water diffusing into the resinous material, resulting in slow-releasing of fluoride.In this study, we investigated the effect of the coating of the fluoride with hydrophobic film on fluoride-releasing behavior of the resinous materials. The sodium fluoride was treated with a silane coupling agent, γ-MPTS, because of its hydrophobic property. XPS analysis revealed that the surface of fluoride was coated with siloxane films, which were formed by condensation reactions between silanol groups, by the treatment of a silane coupling agent. The amount of fluoride released from the resin containing silane-treated sodium fluoride was lower than that containing untreated fluoride at the initial stage. Although the resin containing silane-treated fluoride continued to release it. Moreover, the resin containing silane-treated fluoride presented the inhibitory effects of secondary caries as that containing untreated fluoride. These results indicated that the continuous release of fluoride from the resinous materials was acquired by adding of silane-coated fluoride additives.

氟化物在水wat中的溶解性添加物质，可以在早期消耗大量的氟化物。在这项研究中，扩散到骑行的慢偏见中。我们研究了氟化物与疏水膜对氟化物释放的含氧材料的涂层的影响。氟化物的表面是用硅氧烷膜在硅烷酚基团之间的凝结膜形成的，通过硅烷偶联剂的处理，硅烷偶联剂的含量较低。 Althooth含有硅烷处理的氟化物的树脂继续释放，含有硅烷 - 含硅烷的含量。
