The Effect of Dietary Simulating Solvents on the Color Properties of 3D Printed Restorative Materials

Purpose: The purpose of this study was to investigate the effect of dietary simulating solvents on color properties of 3D printed restorative materials. Materials and Methods: A total of one hundred ninety-two specimens in 1 mm thickness from three different 3D printed restorative materials (Saremco CrownTec, VarseoSmile Crown Plus ve Duraprint Experimental Resin) and one CAD-CAM hybrid ceramic restorative material (Cerasmart 270) were prepared. Test specimens were randomly divided into four groups (n=12) in each color. In the control group, specimens were immersed distilled water; and in the test group specimens were immersed in ethanol, citric acid and heptane, respectively. The quantitative color difference (ΔE) values between the test and control specimens were calculated before and after immersion. Data were analyzed using the statistical software and subjected to ANOVA with two variables (restorative materials and type of dietary simulating solvents) and a post hoc Tukey test were used for multiple comparisons (α=0.05). Results: The results of colorimetric analysis revealed that the dietary simulating solvents effects the color stability of 3D printed restorative materials. There were statistically significant differences in values of color difference (ΔE) of restorative materials (P<.001). The results of two-way ANOVA shoved that restorative materials (p<.05) and type of dietary simulating solvents (p<.05) were significantly affect the color stability (ΔE) values. Interaction terms were also significant (p<.05). Conclusions: Based on the results of the study, the colors of 3D printed restorative materials were affected by dietary simulating solvents. The patients should be warned by the dentists about the discoloration of the restorations which was made of 3D printed restorative materials
