Both commercial materials showed a significant difference regarding translucency at 7F (p = 0.01), and ZLS presented a difference in color higher than one (ΔE 1) at 5F and 7F. Regardless of the number of firings, LD presented a higher BFS compared to ZLS (p = 0.001), and a significant increase in BFS comparing 2F and 7F (p = 0.024). The use of multiple firings can significantly alter the color, translucency, and mechanical strength of CAD/CAM ceramics. The use of multiple firings can significantly alter the color, tr
