摘要：
Methods of using a dental composition having a photobleachable dye and an acidic component with a pKa of less than 4.5 are disclosed. The photobleachable dye is selected from the group consisting of aminoanthraquinone dyes, azo dyes, and combinations thereof. The aged color of the dental composition is substantially the same as the color of the dental composition immediately after hardening.
