    Aim: The objective of this in vitro study was to evaluate the effect of the simulated gastric acid on surface roughness, morphology and micro hardness of CAD/CAM ceramics and comparable with the immersion in the artificial saliva. Materials and methods: A total of 160 sample were prepared (80 were observed for micro hardness with Vickers micro hardness testing machine and the other 80 were observed for roughness with profile meter testing machine and surface morphology changes with field emission scanning electron microscope). Each 80 samples were divided into two categories, with 40 each. Category I (made of IPS e.max CAD) and Category II (made of CEREC blocs C PC). The specimens (3 mm thickness, n=10) were cut, sintered, polished, glazed and cleaned before immersed in artificial saliva and simulated gastric acid solution. Vickers micro hardn.. Read More»
