Objective: The objective of this study is to examine the translucency of four different glass-ceramic materials; IPS e.max Press, CeraMotion, Rosetta SP and Celtra press using different finishing protocols; glazing solely or by both polishing and glazing. Materials and methods: 80 ceramic samples were prepared and divided into four groups (n=20) according to the material used. Each group was subdivided into two subgroups (n=10) according to the thickness of the restoration; 1 mm or 2 mm, which were further divided into two divisions according to the used finishing protocol; subdivision 1 samples were subjected to glazing only, while subdivision 2 were subjected to both polishing and glazing (n=5). Translucency parameters were measured using VITA Easyshade. Result: The present findings showed no statistically significant difference in translucency parameters among different ceramic materials. However, different material thicknesses and finishing protocols demonstrated a statistically significant influence on the translucency parameters (p-value < 0.001). Conclusion: Material thickness and finishing protocols have a direct impact on the translucency parameters of the ceramic restorations.
