Objective: The purpose of this study is to determine the effects of polishing techniques on color stability and surface roughness of lithium disilicate glass ceramic (LDC) and zirconia-reinforced lithium silicate ceramic (ZLS).
Materials and Methods: Two hundred forty disks of LDC and ZLS were prepared. Glazing with the ceramics’ own glazing procedure, a series of sof-lex polishing discs and abrasive stones were used as the different polishing groups. Color differences (∆E*) was evaluated by spectrophotometer, initial and after 48 hours of immersion in various solutions (n=10). Surface roughness (Ra) was evaluated by profilometer (n=10). Data were analyzed by Two-Way ANOVA, and Mann-Whitney U test.
Results: No significant difference in ΔE* values was observed between the sof-lex groups and abrasive stone groups (p>0.05) on LDC. ΔE* values were significantly different with glazed, and abrasive stone groups than sof-lex groups (p<0.05) on ZLS. Within the staining solutions for LDC specimens decreasing ΔE* values were observed in coffee to coke, and then tea and water. However, within the staining solutions for ZLS specimens the highest ΔE* values were observed in coffee, and then equal ΔE* values in coke and tea and the lowest ΔE* values were observed in water. Within the CAD-CAM ceramic materials ΔE* values of ZLS specimens were higher than LDC specimens (p<0.05). Both of ZLS and LDC specimens, the lowest Ra values were observed in glazing groups, which were not statistically different from each other (p>0.05). The highest Ra value in ZLS was observed in group sof-lex. No significant difference was observed among group abrasive stone and sof-lex in LDC specimens (p>0.05).
Conclusion: The amount of staining in the polished ZLS samples was more than the LDC samples. The coffee was determined as the most colorant solution. Abrasive stone may be used instead of sof-lex for polishing of LDC specimens.
