Abstract

Aims: Assess the effect of the surface finish protocol of pressed zirconia reinforced lithium silicate ceramics on the surface roughness and color stability under different pH oral media.

Methodology: A total of 30 samples were used in the present study. The samples were divided into two main groups according to the surface finishing protocol (n = 15); glazed and polished group. Then, subdivided into three subgroups according to the media tested: coffee, carbonated orange juice and artificial saliva as the control group. The surface roughness was measured using optical profilometer quantitatively and with scanning electron microscope qualitatively. Also, Color parameter was measured using spectrophotometer. Afterwards, the discs were immersed in the aging solutions for 12 days simulating 1 year in-vivo. Then, the surface roughness and color change were remeasured after aging.

Result: For surface roughness results, regardless of surface finish protocol the difference between immersion solutions was statistically non-significant where (Coffee ≥ Fanta ≥ AS). Also, irrespective of immersion solutions the difference between surface finish protocol was statistically non-significant where (Glazed ≥ Polished). Regarding the color stability results, regardless of surface finish protocol the difference between immersion solutions was statistically non-significant where (Coffee > Fanta > A.S), furthermore, irrespective of immersion solutions the difference between surface finish was statistically significant where (Glazed > Polished).

Conclusion: Surface finish protocol (glazed and polished), as well as immersion media, showed no effect on the surface roughness of zirconia reinforced lithium silicate restorations. Also, Color stability was significantly affected by the surface finish protocol, while the pH immersion media showed no effect on the color stability.
