Influence of simulated gastric acid on surface roughness and substance loss of different dental veneering porcelains and different surface finishing protocols: An in vitro study

Key Points

• The aim is to examine how simulated gastric acid affects the surface roughness and substance loss of different dental veneering porcelains.
• Conducted in vitro experiments using simulated gastric acid on veneering porcelains.
• Evaluated surface roughness after acid exposure.
• Compared the effects of glazing versus polishing on surface smoothness.
• Simulated gastric acid increased surface roughness.
• Minor substance loss occurred in all tested veneering porcelains.
• Glazing offered better protection than polishing, resulting in smoother surfaces.
