Abstract Ceramic, cement, time and the interaction of the three variables had a statistically significant effect on mean ∆E. The IPS e.max CAD ceramic material shows more color change with time than the IPS Empress CAD ceramic material. Dual-cured resin cements (Paracem & RelyX Unicem) show a higher color change than light-cured resin cement (Filtek Z350). Time had an effect on color stability; the more the time the more the color change occurs |
