This study was investigated the effects of spherical silica fillers on the mechanical properties and anti-carious activity of glass-ionomer cements (GIC). The original GIC and a preparation containing 20wt% spherical silica filler were also examined with regard to their fracture surface and fluoride release. The fillers increased the compressive strength remarkably : up to 17% in the case of silanized spherical fillers (SF). The SF increased the flexural strength by up to 17%. The addition of SF improved the workability and mechanical properties of GIC. When compared with the control (original GIC). The addition of SF significantly improved immediate marginal gap in the tooth cavities and setting shrinkage in Teflon mold up to 63% and 66% respectively. However, fluoride release was significantly reduced. And then, this research showed that addition of 5wt% SF increased the shear bond strength to human enamel and dentin.

本研究研究了球形二氧化硅填料对玻璃离子水门汀 (GIC) 机械性能和防龋活性的影响。还检查了原始 GIC 和含有 20wt% 球形二氧化硅填料的制剂的断裂表面和氟化物释放。这些填料显着提高了抗压强度：硅烷化球形填料 (SF) 的抗压强度高达 17%。 SF 将弯曲强度提高了 17%。 SF的添加改善了GIC的加工性和机械性能。与对照（原始 GIC）相比。 SF的添加显着改善了特氟龙模具中齿腔的直接边缘间隙和凝固收缩率，分别高达63%和66%。然而，氟化物的释放量显着减少。然后，这项研究表明，添加 5wt% SF 增加了对人牙釉质和牙本质的剪切粘合强度。
