Sixty amalgam-restored blocks were treated with 0.65 mm (±0.10 mm) resin-based opaquer. Low-translucency (LT) lithium disilicate CAD/CAM blocks from two different manufacturers (Ivoclar IPS e.max CAD and GC Initial LiSi) were sectioned, crystallized (e.max), and polished, then divided into three subgroups according to their thickness (1.0, 1.5, and 2.0 mm, n = 30). The ceramic slices were treated and bonded to the three substrate types (control, opaqued amalgam, and nonopaqued amalgam) using a resin-luting cement. The masking effect of the resulting ceramic-substrate assemblies was investigated using a spectrophotometer and polarized digital photocolorimetric (PDPC) analysis. CIE L*a*b* coordinates were measured, and color difference analysis (ΔE<sub>00</sub>) was performed using the CIE ΔE<sub>00</sub> formula. Acceptability and perceptibility thresholds were set at ΔE<sub>00</sub> ≤ 1.8 and ΔE<sub>00</sub> ≤ 0.8, respectively. The data were statistically analyzed using three-way and two-way ANOVA, followed by Tukey's test (α ≤ 0.05).</p><p><strong>Results: </strong>Spectrophotometric analysis showed that, for nonopaqued amalgam substrate, IPS e.max achieved ΔE<sub>00</sub> mean (SD) of 4.2(0.4), 2.8(0.3), and 2.1(0.2), for 1.0, 1.5, and 2.0 mm thicknesses, respectively. Initial LiSi achieved ΔE<sub>00</sub> mean (SD) of 3.8 (1.1), 2.8(0.9), and 2.7(0.4) for 1.0, 1.5, and 2.0 mm thicknesses, respectively. When the substrate was opaqued amalgam, IPS e.max and LiSi both resulted in a mean ΔE<sub>00</sub> of 2.3(0.7). As the thickness increased to 1.5 and 2.0 mm, IPS e.max achieved an acceptable (ΔE<sub>00</sub> = 1.3(0.4)) and an excellent (ΔE<sub>00</sub> = 0.8(0.3)) masking, respectively. Initial LiSi achieved a moderately unacceptable color difference (ΔE<sub>00</sub> = 2.0(0.8)) at 1.5 mm and an acceptable masking (ΔE<sub>00</sub> = 1.5(0.6)) at 2.0 mm.
