To assess color and translucency change (∆E and ∆TP) of 3D-printed (Varseosmile crown plus, VS) and milled resin-ceramic hybrid material (Cerasmart, CS) compared to enamel (E) when immersed in distilled water (DW) and coffee (C). Sixty VS, CS, and E specimens were immersed in DW and C for 30 days. Statistics analysis using t-test and one-way ANOVA at p≤0.05. ∆E of VS, CS, and E significantly increased when immersed in coffee (p<0.001, p<0.001 and p=0.01, respectively). E has more ∆E than VS and CS (p<0.001). The translucency of VS and CS was reduced after water and coffee immersion. The translucency of E was increased after immersion in water and coffee. ∆TP of VS, CS, and E were not different between immersion in water and coffee at p=0.08, p=0.43 and p=0.72, respectively. Therefore, DW and C have distinct effects on the ∆E and ∆TP among VS, CS and E.
评估 3D 打印（Varseosmile 牙冠加，VS）和铣削树脂陶瓷混合材料（Cerasmart，CS）与牙釉质（E）在浸入蒸馏水（DW）和咖啡（C）时的颜色和半透明度变化（∆E 和 ∆TP）。将 60 个 VS、CS 和 E 标本分别浸入 DW 和 C 中 30 天。使用 t 检验和单因素方差分析进行统计学分析，p≤0.05。当浸入咖啡时，VS、CS 和 E 的 ∆E 显著增加（p<0.001、p<0.001 和 p=0.01，分别）。E 的 ∆E 大于 VS 和 CS（p<0.001）。浸入水和咖啡后，VS 和 CS 的半透明度降低。E 的半透明度在浸入水和咖啡后增加。VS、CS 和 E 在 DW 和 C 中的 ∆TP 之间没有差异，p=0.08、p=0.43 和 p=0.72，分别。因此，DW 和 C 对 VS、CS 和 E 的 ∆E 和 ∆TP 有明显影响。
