Abstract

The present study aimed to compare the color stability of zirconia cemented veneers, using self-etch adhesive cement after curing with various systems and aging process. Materials and methods: A total of 27 veneers zirconia samples were cemented using resin cement on 27 labially prepared extracted anterior teeth to reach a flat surface, and classified into three groups according to the light curing units (LCU); Group I (Cured with Polywave Ivoclar Bluephase style LCU), Group II (Cured with Polywave Woodpecker iLED LCU), Group III (Cured with Monowave 3M Elipar LCU). Results: Monowave LCU exhibited significantly higher color changes than the polywave LCU ([P < 0.05] [ΔE 2.94 ± 0.44]). Interaction between polywave polymerizing units and resin cement was not significant (P > 0.05). Conclusion: This study concluded that different light curing systems have a significant effect on the final color of resin cement used in cementation of zirconia veneers. Polywave LCUs provide better color stability of zirconia veneers.
