Comparison to Color Stability Between Amine with Benzoyl Peroxide Includes Resin Cement and Amine-reduced, Amine-free, Lacking of Benzoyl Peroxide Resin Cements After Thermocycle

Comparison to Color Stability Between Amine with Benzoyl Peroxide Includes Resin Cement and... Objective:This study aims to compare the color change (ΔE) of 5 resin cements (Panavia SA, Panavia V5, RelyX U200, Variolink NLC clear and +1) after thermocycling. Changes in color of specimens were determined after 10,000 cycles of thermocycling by spectrophotometer in the CIELAB.Materials and Methods:Ceramic disks, simulating laminate veneers, with thicknesses of 0.5, 0.7, and 1.0 mm (A1, IPS e.max) were fabricated. Color differences (ΔE) between the control and test groups were calculated. Data were statistically analyzed by 2-way analysis of variance (ANOVA). Also, Tukey’s multiple comparison tests were applied to know the difference between the groups (α = 0.05).Results:The factors of cement type and thickness of ceramic showed significant influence on ΔE values (P < .05). After thermocycling, all resin cements, except benzoyl peroxide including resin cement (Pan SA), were showed clinically acceptable to color change limits (ΔE < 3.3).

Abstract

Objective:This study aims to compare the color change (ΔE) of 5 resin cements (Panavia SA, Panavia V5, RelyX U200, Variolink NLC clear and +1) after thermocycling. Changes in color of specimens were determined after 10,000 cycles of thermocycling by spectrophotometer in the CIELAB.Materials and Methods:Ceramic disks, simulating laminate veneers, with thicknesses of 0.5, 0.7, and 1.0 mm (A1, IPS e.max) were fabricated. Color differences (ΔE) between the control and test groups were calculated. Data were statistically analyzed by 2-way analysis of variance (ANOVA). Also, Tukey’s multiple comparison tests were applied to know the difference between the groups (α = 0.05).Results:The factors of cement type and thickness of ceramic showed significant influence on ΔE values (P < .05). After thermocycling, all resin cements, except benzoyl peroxide including resin cement (Pan SA), were showed clinically acceptable to color change limits (ΔE < 3.3). On evaluating the effects of ceramic thickness on color change after thermocyle aging, control group (no ceramic thickness) showed color change (P < .05) visually.Conclusion:Amine-reduced, amine-free and lacking benzoyl peroxide resin cement showed minimal color change and better color stability.
