Abstract :Aim: This study aimed to evaluate the effect of different solutions and a cleaning tablet on the color stability and surface roughness of different types of artificial teeth. Materials and Methods: Conventional polymethylmethacrylate (PMMA), cross-linked isosite (CLI), and double cross-linked acrylic (DCA) teeth were allocated into 4 groups according to the immersion protocol to be applied as AS (artificial saliva immersion for 14 days), AS+C (artificial saliva immersion for 14 days and then applying Corega for 1 week, 8 hours a day), Co (immersion in coffee solution for 14 days), Co+C (immersion in coffee solution for 14 days and then applying Corega for 1 week, 8 hours a day). The specimens\\\' color (L*, a* and b* values) and surface roughness variables were measured at the baseline and after immersion protocols. The color changes (ΔE) of the specimens were calculated using the CIEDE2000 formula. Data were evaluated by the Kruskall Wallis H and the ANOVA test. The Wilcoxon Sign and Bonferroni tests were used for comparisons (α=0.05). Results: The lowest ΔE00 value was found in Group PMMA exposed to Corega suspension after immersion in artificial saliva [Group PMMA-AS+C: 2.33(1.72)]. According to the ΔE00 values, there was no statistically significant difference according to the materials of both the solution and the artificial teeth (p>0.05). None of the test groups showed significant difference in baseline surface roughness values (p>0.05). However the protocol Co+C increased the surface roughness of CLI teeth (p<0.05). Also, PMMA teeth showed higher surface roughness for protocols AS and AS+C. Conclusion: According to the results of this in-vitro study, coloring solutions affected surface roughness to varying degrees. Clinicians should consider cost-effective aspects for aesthetic expectations when choosing artificial teeth.
