RESULTS
Table 3 shows the mean surface roughness observed with different finishing and polishing systems. Results of statistical analysis are shown in Table 4. Mean Ra values ranged from 0.09 to 0.3 μm for Esthet-X and from 0.18 to 0.3 μm for Solitaire II with different polishing systems. For both the materials, the smoothest surface was obtained with mylar strip and the roughest with Super Snap. The lowest Ra values obtained for Esthet-X and Solitaire II were 0.09 μm and 0.18 μm, respectively.
