One-way ANOVA Fisher’s least significant difference post hoc test for individual group comparison with other groups for 2 different time interval color differences ΔE00(I) and ΔE00(II). Std – standard; ΔE00(I) – color change between pre-cementation and post-cementation; ΔE00(II) – color change between post-cementation and post-thermocycling. Statistical Interpretation: test employed=Fisher’s least significant difference (LSD) post hoc test; level of the degree of significance was determined by value of ^* significant.
