An evaluation of color stability of reinforced composite resin compared with dental porcelain in commonly consumed beverages.
The effect of tea, cola, orange juice, and distilled water on the color stability of a porcelain (VITA VMK 95) and a reinforced composite rein (GC Gradia) was evaluated. Standardized specimens for each material was prepared. Specimens from each group were immersed in staining solutions at 50 degree Celsius for 30 days. Tea caused the most significant color change. DeltaE of all of the materials was changed after the immersion in all of the staining solutions during the experimental process.
