p1:The significance of surface roughness differences between hybrid ceramic groups at the same beverage groups and same duration times (*: p1 < 0.05)
p2:The significance of the surface roughness differences between different duration times in the same beverage group for each ceramic group (**: p2 < 0.05). Lowercase letters used for multiple comparisons (a,b,c)
p3:The significance of surface roughness differences between different beverage groups at the same time intervals for each ceramic group (***: p3 < 0.05). Capital letters used for multiple comparisons (A,B,C,D)
The mean difference (p) was set significant at the 0.05 level
Similar superscript letters indicate statistically indifference between groups (p < 0.05)
Dissimilar superscript letters indicate statistically significant differences between groups (p < 0.05)
