Abstract

Purpose: This in vitro study assessed the color of computer-aided design/computer-aided manufacturing (CAD/CAM) reinforced composite material (BRILLIANT Crios) under different shades of tooth substrates. Materials and methods: Around 21 rectangular BRILLIANT Crios slices (A3 HT, 12 × 10 × 1 mm) and 21 composite resin samples (IPS Natural Die Material; 12 × 10 × 2.5 mm) with three different shades (ND3, ND5, and ND7) were prepared. Baseline color measurements (L*, a*, b*) were obtained using a spectrophotometer. Each slice was then cemented to a composite resin sample with self-adhesive transparent dual-cure resin cement (SpeedCEM®Plus) and designated as group I (ND3), group II (ND5), and group III (ND7). Final color measurements were taken, and the color difference (ΔEab*) was calculated. Data were analyzed using analysis of variance (ANOVA) followed by post hoc Tukey's test for multiple comparisons. Results: Different shades of substrate significantly affected ΔEab (p < 0.001). Group III (ND7) (4.18 ± 0.15) exhibited the highest ΔE value, while group I (ND3) (2.95 ± 0.11) demonstrated the lowest ΔE value. Groups I (ND3) (−1.83 ± 0.13) and group III (ND7) (−2.11 ± 0.15) exhibited higher ΔL compared to group II (ND5). Group I (ND3) exhibited the highest Δa value (0.85 ± 0.07), while group II (ND5) displayed the lowest (0.77 ± 0.11). The post hoc test showed a significant difference between the groups compared for ΔE, ΔL, and Δa values. Concerning Δb, group III (3.45 ± 0.17) had a higher value while group I (2.15 ± 0.17) had the lowest, while group II (2.97 ± 0.16) revealed an insignificant difference with other groups. Conclusion: Color change (ΔE) of group I (ND3) and group II (ND5) was clinically acceptable while that of group III (ND7) was unacceptable. The resulting optical color of CAD/CAM BRILLIANT Crios was greatly influenced by the color of the underlying tooth substrate. The darker the shade of the tooth substrate, the less ability of the BRILLIANT Crios to mask the darker shade. For patients with deeply discolored teeth and requiring esthetic restoration, it's recommended to use high-opacity ceramic material rather than indirect composite material.
