title: Testing of color stability of composites.
abstract: The color stability of five commercial composites was evaluated according to a proposed modification of ADA Specification No. 27. After exposure of 24 hours to a sunlamp, light-cured composites showed greater changes in color than conventional and microfilled, amine-cured composites. Factors of evaluator and viewing condition affected discrimination of color differences.
