Abstract

The effect of prior acid etch on the rate of Sn3F3PO4 formation subsequent to in vitro SnF2 interaction with human dental mineral has been investigated using light microscopy, surface replicas, and internal reflection spectroscopy. Results showed that Sn3F3PO4 forms more rapidly on etched surfaces as compared with nonetched controls. The observed accelerated rate was attributed to increased reaction surface provided by prior acid etch plus a rougher surface conducive to crystal nidus formation.

摘要

利用光学显微镜、表面复型技术和内反射光谱法，研究了在体外氟化亚锡与人牙矿物质相互作用后，预先酸蚀对随后三氟磷酸锡（Sn3F3PO4）形成速率的影响。结果表明，与未酸蚀的对照相比，在酸蚀表面上Sn3F3PO4的形成更快。观察到的加速速率归因于预先酸蚀提供的反应表面增加以及更粗糙的表面有利于晶核形成。
