Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

The effect of coffee thermocycling and color correction serum on the colorimetric properties and hardness of CAD‐CAM restorative materials

Journal of Prosthodontics, EarlyView.
Abstract Purpose To compare the stainability, translucency, opalescence, whiteness, gloss, and hardness of 4 computer‐aided design and computer‐aided manufacturing (CAD‐CAM) restorative materials after simulated coffee drinking and color correction. Materials and Methods Four CAD‐CAM blocks were investigated (n = 40): resin nanoceramic (Cerasmart, CS),

The cognitive role of concept variability

Mind &Language, EarlyView.
I present and defend concept variability, the view that concepts can admit of indefinitely many variations and changes in their representational contents without thereby losing their identity. I argue that the variability of concepts is central to their role in enabling cognition, and thus that a concept's content variability is, despite philosophical ...
