<br/><br/> This study determined the reliability of ceramic surface protection against the effect of a manufacturer's proposed bleaching protocol on the surface roughness and color stability. A total of 40 ceramic discs were constructed (12mm color diameter X 2mm thickness) according to manufacturer's instructiions; 20 discs of each material: hydrothermal low fusing ceramic
