Introduction: The advantages of glass ceramics are combined with those of resin in hybrid ceramics. There are, however, few studies concerned concerning the characteristics of surface roughness in hybrid materials.

 Objectives: The roughness of dental restorations milled from hybrid CAD/CAM blocks will be studied to determine the effect of different surface finishing techniques.

Methods:Twenty-four (24) polymer infiltrated ceramic network  (Enamic) samples were made, each measuring  (3 millimeters in length, 8 millimeters in breadth, and 3 millimeters in height). Enamic samples consist of three subgroups. (8) samples categorised by surface treatment. A universal testing instrument was used to evaluate the surface roughness. To test for a statistically significant difference between the three groups, a one-way analysis of variance (ANOVA) was used. When differences between groups are found to be statistically significant using analysis of variance (ANOVA), the data are put through the Least Significant Difference (LSD) test for further examination. T-test to determine where the deviations are coming from.

Results: On -way (ANOVA) test was used to analyses the results, the differences between the groups were statistically significant.

Conclusions: In this study, all surface treatments provided adequate surface roughness values compared with them, but (FE) and (DE) show smoother surface than (GE) .
