A New Modality for the Investigation of the Remineralization Efficacy of a Self-curing Adhesive System

本研究的目的是了解利用超声设备和光学相干断层扫描（OCT）的自愈合粘合系统的脱矿效果。利用脉冲接收器和换能器测量了纵向超声波的传播时间。随着时间的推移，储存在软化溶液中的标本的声速下降，但是，涂层标本有一个显着较高的声速比那些没有涂层。从OCT观察，观察到明显的变化，在B扫描模式，并检测到信号强度下降的标本与酸攻击。从该研究的结果来看，含有PRG填料的涂层材料因此似乎减少了牙釉质的脱矿。牙齿结构的脱矿情况可以通过使用超声装置和OCT非破坏性地测量。

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.
