Abstract
Glass ionomer cements (GICs) are clinically appealing dental materials with unique characteristics that make them suitable as restorative and luting materials. However, the application of GIC under mechanical loading has been limited by its poor mechanical performance. The aim of this study was to investigate the effect of date seed (DS) microparticles as a reinforcement material for conventional glass ionomer cement. Date seed powder was incorporated into the powder component of GIC at 1, 3, and 5 wt%. Glass powder without date seed powder was used as a control sample. Glass ionomer cement reinforced with DS was analyzed using various mechanical properties such as compressive strength (CS), Vickers microhardness (VH), and impact strength (IS). The surface inspection was investigated using a scanning electron microscope (SEM). The nature of DS and GIC-DS powder was determined using Fourier transform infrared (FTIR). The results showed that the incorporation of 5 wt% of DS reinforcement into GIC significantly improved the microhardness, impact strength, and compressive strength compared to the control sample of GIC. On the other hand, the results revealed that the weight percentage of DS plays a noteworthy role in deciding the properties of glass ionomer cement. The FTIR results revealed that a physiochemical interaction occurred between the GIC and the DS. The results indicated that the use of date seed powder as reinforcement can enhance the mechanical properties of glass ionomer cement in artificial saliva.
