Glass ionomer cements (GIC) also known as polyalkenoate cements have been used as dental luting material for decades. However, there are certain limitations with respect to its biomechanical properties. Therefore, the aim of current investigation was to synthesize and characterize silver nanoparticles (SNP) using a green approach and incorporating the synthesized SNP in commercially available GIC formulation. Methodology. SNP were synthesized using a green approach of chemical reduction and analysed by spectroscopy and Transmission Electron microscopy. SNP reinforced GIC in 10, 30 and 50% formulations were assessed for microhardness, compressive strength, color stability and Nano-computerized tomography was used for pore analysis. Results. Results from UV–vis spectroscopy, Dynamic Light Scattering, Zeta potential, Transmission Electron Microscopy and Fourier Transform Infrared Spectroscopy revealed that the particles were spherical and polydisperse in nature with an average diameter of 122 nm. The synthesized particles had a positive surface charge of 74 mV. Their incorporation into the Glass ionomer cement (GIC) revealed non-significant results on microhardness and compressive strength. Significant color change was observed and Nano-CT revealed pores within the set cements. Conclusion. Nevertheless, the biosynthesized silver nanoparticles have much broader clinical application and can be used to reinforce properties of existing dental biomaterials. They can be conveniently synthesized by the biogenic route adapted in the current investigation. However, their addition to the luting cement still warrants further in-depth investigation.

玻璃离聚物粘固剂 (GIC) 也称为聚链烯酸酯粘固剂，几十年来一直用作牙科粘接材料。然而，其生物力学特性存在一定的局限性。因此，当前调查的目的是使用绿色方法合成和表征银纳米粒子 (SNP)，并将合成的 SNP 纳入市售 GIC 配方。方法论。SNP 使用绿色化学还原方法合成，并通过光谱学和透射电子显微镜进行分析。评估了 10%、30% 和 50% 配方中 SNP 增强的 GIC 的显微硬度、抗压强度、颜色稳定性，并使用纳米计算机断层扫描进行孔隙分析。结果. UV-vis 光谱、动态光散射、Zeta 电位、透射电子显微镜和傅立叶变换红外光谱的结果表明，这些颗粒在性质上是球形和多分散的，平均直径为 122 nm。合成的颗粒具有 74 mV 的正表面电荷。将它们加入玻璃离子水门汀 (GIC) 后，显微硬度和抗压强度的结果并不显着。观察到显着的颜色变化，纳米 CT 显示凝固的水泥内有孔隙。结论. 然而，生物合成的银纳米粒子具有更广泛的临床应用，可用于增强现有牙科生物材料的特性。它们可以通过目前研究中采用的生物途径方便地合成。然而，它们添加到粘合水泥中仍然值得进一步深入调查。
