The color stability of three structurally different resin-based composites was investigated to test the influence of exposure of water on it. Six comparable Vita shades of three different resin-based composite systems were selected and the samples were studied with a spectrophotometer equipped with an integrating sphere. The results show that one of the three materials involved in the study depicted an unacceptable color shift for all shades. It was concluded that for some products, aging of composites in water leads to opacity variation and color instability.

Abstract
The color stability of three structurally different resin-based composites was investigated to test the influence of exposure of water on it. Six comparable Vita shades of three different resin-based composite systems were selected and the samples were studied with a spectrophotometer equipped with an integrating sphere. The results show that one of the three materials involved in the study depicted an unacceptable color shift for all shades. It was concluded that for some products, aging of composites in water leads to opacity variation and color instability.
