Abstract:
The purpose of this research project is to understand how certain liquids can alter dental ceramics durability. 5 x 2 x 20 mm dental ceramics specimens (Vita Metall-Keramik) will be fabricated and polished using 240 SiC paper. 40 specimens will be prepared and divided into 4 groups. Each group will be placed in its specific liquid: spring water, diet Pepsi™, Pepsi™; or 50/50% by volume distilled water and ethanol at 37 degree C, simulating the mouth. Later, the specimens will be cyclic loaded and fractured in a 3-point bending set-up, utilizing an Instron testing device with a 50 Kg load cell. At this point in the research, the ceramics are being fabricated. By the beginning of April the specimens will be completed and testing can begin.
