  1. *Multiple comparisons between surface treatment groups for each veneer material are shown as letters, and values having the same letters are not significantly different for the Tukey HSD test (p > 0.05)
  2. ** Pairwise comparisons of the same surface treatment applied ILC and LDC veneer materials, according to the independent sample t-Test
