Delayed Light Activation Improves Color Stability of Dual-Cured Resin Cements.

Purpose: To evaluate the color change caused by post-irradiation conversion (ΔE and ΔE ) and artificial aging (ΔE ) of resin cements light activated through ceramics of different opacities immediately and 6 minutes after manipulating the material.

Materials And Methods: Resin cement disks (Allcem and LuxaCore) were light activated through ceramics (without ceramic, e.max HT, LT, and MO) immediately and 6 minutes after the manipulation (n = 10).
