Sixteen ceramic disk specimens (10mm) hight, and (8mm) thick were made from Felspatic Lucite (FPL) (K2O.Al2O3.4SiO2), and Flouropatite ceramic (Ca10P6O24F2). The specimen were then immersed in citric acid (C6H8O7), tartaric acid (C2H4O6), and benzoic acid (C7H6O2) at (37) Co for (50,100,150,200) hours. Microstructure of the specimens was detected using SEM before and after the immersion, it has been found that FP dental glass ceramic microstructure is more stable than FPL composite dental ceramic in the tested food acids, and citric acid has the largest damaging effect on both FP, and FPL.
Key Words:- Dental Ceramic, Food acids, Etching.
