本研究探讨了基质对添加羟基磷灰石的常规玻璃离子水门汀(GIC)中元素行为的影响。用多孔球形羟基磷灰石替代8~16wt%的GIC粉末制备AIC样品。有一半的样品去除了富含基质的层。使用氟化物电极和电感耦合等离子体发射光谱仪对具有和没有富含基质层的AIC和GIC样品进行了多元素分析。用三磷酸腺苷发光法测定了样品对变形链球菌的抗菌活性。AICS的矿物离子释放性能和抗菌活性均优于GIC。有基质富集层的GIC和AIC样品的元素释放量显著高于无基质富集层的GIC和AIC样品。含有AICS的变形链球菌悬浮液的发光强度明显低于含GIC的悬浮液。
The present study investigated the role of matrix on the behavior of elements in HAp-added conventional glass ionomer cement (GIC), referred to as “apatite-ionomer cement (AIC)." The AIC samples were produced by replacing 8-16 wt% of GIC powder with porous spherical-shaped HAp. One-half of the samples had the matrix-rich layer removed. The AIC and GIC samples with and without a matrix-rich layer underwent multi-element analysis using a fluoride electrode and ICP-AES. The antibacterial activity of the samples against S. mutans was also evaluated using ATP-luminescence methods. The mineral ion release properties and antibacterial activity of AICs were superior to those of GIC. The concentrations of elements released from GIC and AIC samples with a matrix-rich layer were significantly greater than those from GIC and AIC samples without the matrix-rich layer. The luminescence intensities of S. mutans suspensions containing immersed AICs were significantly lower than those of suspensions containing GIC.
