Table 2 One-way ANOVA test results for comparison of color, contrast ratio and translucency between studied ceramics (Nacera Pearl Multi-Shade/Ceramill Zolid FX multilayer) after surface alteration (finishing/polishing) with 2 different commercial kits and immersion in media (saliva/chlorhexidine).

SD – standard deviation; p – probability value; Gp – group; Basis of Grouping – first alphabet represents type of ceramic (N=Nacera Pearl Multi-Shade, C=Ceramill Zolid FX Multilayer), Second alphabet represents surface treatment/adjustment (G=glazed, D=with Diasynt Plus, Diacera, S=with SUN) for finishing/polishing, third alphabet represents the medium used (S=saliva and Ch=chlorhexidine). [Example Gp NDCh represents Nacera ceramic adjusted with Diasynt Plus and immersed in chlorhexidine]. Statistical Interpretation: Test employed – One way ANOVA; level of the degree of significance was determined on the value of p ^* significant. Clinical acceptance (perceptible) threshold (CAT/CPT) (indicated by ): (1) Color difference (ΔE), []: ΔE = ≤1.00 – clinically not appreciable; ΔE = 1.0–3.3 – perceivable only by skilled operators therefore clinically acceptable; ΔE = ≥3.3 – appreciable by anyone (layman) therefore clinically unacceptable (2) Translucency perception threshold (TPT) []: CR (Y
