[The study of color stability of ceramic stains subjected to glazing temperature].
Ceramic stains are used to modify the final colors of ceramic dental restorations. They are not color stable when subjected to glazing temperature. In order to understand the color change characteristics, the study tested the color stability of the five Vita VMK68 stains. The international color standard CIE1976LAB color system and CS-5 Spectrocolorimeter are used. The results indicate: significant color changes are noted for five stains; the color change characteristics among them are different; yellow-brown stain shows the most color unstability after firing.
