| المستخلص : | Glass Ionomer Cement (GIC) is one of the important dental materials used in dental clinics, which is usually used in temporary restorative stages. This study aims to evaluate the effect of adding Al micro particles to GIC powder (Riva self-cure) on the mechanical and physical properties. The results showed that the addition of Al micro particles has improved the compressive strength and biaxial flexural strength where the highest values were at 3 wt. %, and then the compressive strength and biaxial flexural strength decreased with increasing the added ratios. The addition of Al particles improved the surface Vickers microhardness values where the highest value was at 5 wt. %. The addition of Al has decreased the wear resistance of GIC; however the wear resistance increased with increased adding ratios. The most acidic beverages (the lowest value of pH) were the most effective in increasing the absorption and solubility percentage of Al samples. Orange juice was more effective followed by cola and then coffee and tea were less effective. We recommend that patients reduce these acidic beverages because they have a harmful effect on dental fillings. |
