The effect of cold drinks on the coloration of resin-containing restorative materials

Aim: Resin-containing restorative materials are widely used in the restoration of teeth. Our aim in this study is to examine the color change of beverages consumed cold on resin-containing restorative materials. Methodology: Samples were prepared using composite resins and resin-based CAD/CAM blocks. All prepared samples were kept in cold tea, cold coffee, coke, energy drink, and distilled water after polishing. The color values of the samples were measured with a spectrophotometer at the beginning, on the 1st, 7th and 30th days, and the color change values were calculated with the CIEDE2000 formula. Statistical analysis of color change values was performed using two-way analysis of variance (ANOVA) and Tukey multiple comparison tests (p<0.05). Results: While there was no statistically significant difference in the color changes of the resin-containing dental materials at the end of the 1st day (p>0.05), at the end of the 7th and 30th days, cold tea caused the statistically highest color change (p<0.05). There was no statistically significant difference between the color change values of cold coffee, coke and energy drink on the materials in all time periods (p>0.05). Composite resins showed more color change than resin-based CAD/CAM blocks (p<0.05). Conclusion: Cold tea causes the most discoloration on resin-based materials. While the resin-containing CAD/CAM blocks showed a color change under the AT value in all cold drinks, the composite resins showed a color change above the AT value in cold tea and coffee.   How to cite this article: Altıparmak ET, Aybala Oktay E, Karaoğlanoğlu S, Aydın N, Ersöz B, Özarslantürk S.
