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.

Comparison of mean surface roughness between finishing/polishing systems
For Esthet-X, specimens treated with PoGo were found to be significantly smoother than specimens treated with Super Snap. In Solitaire II group, no significant difference in Ra values was observed between PoGo and Super Snap.
On comparing Solitaire II and Esthet-X, the latter provided a significantly smoother surface when PoGo polishing system was used. Super Snap polishing system produced the same surface roughness for both the materials.
