The purpose of this study was to know demineralization effect of self-healing adhesive system utilizing ultrasonic device and optical coherence tomography (OCT). The propagation time of longitudinal ultrasonic waves was measured by a pulser receiver with a transducer. The sonic velocity decreased over time for specimens stored in demineralising solution; however, coated specimens had a significantly higher sonic velocity than those without coating. From the OCT observations, obvious changes in B-scan mode were observed, and decreases in signal intensities were detected for the specimens with acidic attack. From the results of this study, the coating material containing PRG fillers therefore appeared to reduce the demineralisation of enamel. The condition of demineralization of the tooth structure could be measured non-destructively by using an ultrasonic device and OCT.

本研究的目的是了解利用超声波装置和光学相干断层扫描（OCT）的自愈粘合系统的脱矿效果。纵向超声波的传播时间由带有换能器的脉冲接收器测量。对于储存在脱盐溶液中的样本，声速随着时间的推移而降低；然而，有涂层的样品比没有涂层的样品具有明显更高的声速。从OCT观察中，观察到B扫描模式发生明显变化，并且检测到受酸侵蚀的标本信号强度下降。从这项研究的结果来看，含有 PRG 填料的涂层材料似乎可以减少牙釉质的脱矿质。可以使用超声波装置和OCT来非破坏性地测量牙齿结构的脱矿情况。
