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

Abstract

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 (p0.05), at the end of the 7th and 30th days, cold tea caused the statistically highest color change (p0.05). Composite resins showed more color change than resin-based CAD/CAM blocks (p
