Aim and objective: This study aimed to evaluate the color stability, translucency, and wettability of a lithium disilicate dental ceramic. Materials and methods: Forty specimens (6 × 1 mm) of lithium disilicate dental ceramic were fabricated. Initial color and translucency readings were measured using a spectrophotometer. Then, the specimens were randomly separated into four groups (n = 10), according to the different types of surface treatment (control: control group; HF + S: hydrofluoric acid gel and silane; Al + HF + S: Al2O3, hydrofluoric acid gel, and silane; Al + S: Al2O3 and silane) and new color and translucency readings were done. The wettability was analyzed using the sessile drop method in all specimens, and the results were statistically analyzed using one-way ANOVA and the Tukey test (p < 0.05). Results: The results showed higher color and translucency changes to the groups treated (HF + S, Al + HF + S, and Al + S), different (p < 0.05) from the control group, and without significance between them. All groups demonstrated different wettability (p < 0.05), lower for the control group. Conclusion: It is possible to conclude that the surface treatment can influence the color, translucency, and wettability of lithium disilicate dental ceramics.
