Abstract

Aim: The aim of this study was to compare the effects of different surface finishing treatments applied to two different CAD/CAMmaterials on the color stability after thermal aging with coffee and cola.Materials and Methods: Polymerized resin nanoceramic (LAVA Ultimate, LU) and lithium disilicate glass-ceramic (IPS e.max CAD, EC)were examined in the study. The samples with A1 HT color at a size of 14 x 12 mm and a thickness of 0.5 ± 0.05 mm were preparedfrom these ceramic materials (N=144). Color measurement of each specimen was calculated with a spectrophotometer using colorparameters on a gray backing between baseline color, polishing/glazing and after 5000 cycles of coffee and cola thermocycling.ANOVA and the Fisher’s LSD test were used for testing statistical significance (p < 0.05).Results: LU exhibited higher color change values than EC after thermal aging. In the EC group, glazing provided statistically differentresults as compared to the manual and control groups (p < 0.05). The lowest color change for all stages was observed in IPS e.maxCAD ceramics that were treated by glazing.Conclusion: In terms of color stability, glazing can be recommended for EC, and manual polishing as an alternative to glazing for LU.
