摘要

该研究涉及早期龋病发展过程中最外层牙釉质表面最早的化学变化。牙釉质样品在酸化羟乙基纤维素溶液(pH = 5.1)中体外脱矿1 ~ 288 h后，在0.04微米深度用卢瑟福后向散射光谱测定Ca/P摩尔比。测量到的Ca/P比值在初始值附近振荡。这种行为被解释为脱矿/再矿化联合过程。

[The development of initial enamel caries--a phenomenon of interfacial reactions].

The investigation deals with earliest chemical changes in outermost enamel surfaces during initial caries development. After in vitro demineralization of enamel samples in acidulated hydroxyethylcellulose solution (pH = 5.1) for periods between 1 and 288 h the Ca/P molar ratios were determined in depths of 0.04 micron using the Rutherford Backscattering spectroscopy. The measured Ca/P ratios oscillate around the initial value. This behaviour is interpreted as a combined de/remineralization process.
