Color Stability of New Composite Restorative Materials Under Accelerated Aging

The color stability of seven microfilled and conventional composites under conditions of accelerated aging was evaluated by reflection spectrophotometry. During early aging the composites generally became darker, more chromatic, and more opaque. The in vitro color stability of the microfilled composites was better and less influenced by erosion than the conventional composites.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66615/2/10.1177_00220345800590120801.pd
