利用扫描电镜（SEM）和傅里叶变换红外光谱（FTIR）对玻璃离聚体修复体与牙本质之间的中间层进行了形态学观察。扫描电镜显示，牙本质与玻璃离聚体之间有较强的结合，并形成中间层。通过离聚体/牙本质界面区连续刮屑的FTIR光谱表明，中间层主要由矿物氟化碳酸磷灰石组成。在牙齿和修复体之间的界面上存在这种少量可溶的矿物质，可以提供对继发性龋齿的高抵抗力，因此可能具有重要的临床意义。
The intermediate layer between a glass ionomer restoration and dentin was examined morphologically by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). SEM showed strong bonding between the dentin and glass ionomer and formation of an intermediate layer between them. FTIR spectra of successive scrapings through the ionomer/dentin interface zone showed that the intermediate layer is composed primarily of mineral fluoridated carbonatoapatite. The presence of this sparingly soluble mineral at the interface between the tooth and the restoration may provide high resistance to secondary caries and may, thus, be of great clinical importance.
