Color selecting 3times a day and 5 times in week was done by dentist. After 480 repeated cycle of this procedure According to CIELab system, primary color of ten of the samples were measured by Konica Minolta spectrophotometer as the control group. Color indices were measured by using Vident spectrophotometer in the CIELAB system and statistical analysis was performed by Two-way ANOVA.
Results: The rate of color change indices presented that the color changing (ΔE) of by Deconex+53 was 1.23∓0.55 and for Desomed was 3.69∓1.3, respectively. So the ΔE of Desomed was 2 times more than Deconex +53. The results of this study showed that the discoloration of Desomed is statically significant higher than Deconex (p<0.001).
