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.

IntroductionToothpaste has long been a part of our daily lives. In 500 BC, Indochina provided a recipe for a tooth-cleaning paste (1). Both France and the United States invented flexible lead or tin tubes in 1846, and toothpaste was first sold in bendable tubes in the US and Germany in 1896. In 1873, Colgate began manufacturing toothpaste in jars in the United States. The first fluoride toothpaste was introduced in the United States in 1955 (1).Toothpaste has always been offered to consumers as changing and developing oral hygiene products. The most common and simplest method for providing oral dental care is mechanical cleaning of the teeth using toothbrushes and interface brushes. Toothpaste is used to increase the mechanical cleaning efficiency of toothbrushes and to obtain additional effects such as whitening. Because of this state, it can be ensured that the teeth are protected from plaque and tooth decay (2).The oral hygiene products market aims to continuously improve the content of existing products and to develop new products to satisfy the expectations of consumers. Although toothpaste contains all basic active ingredients that protect from plaque and decay, various substances have recently been added to them (3).The most common issue that makes patients disturbed is the discoloration of the teeth. Therefore, the ingredients added to toothpaste are formed according to consumer demands.Due to these demands for tooth-whitening products and many new-toothpaste formations have been created to remove or prevent extrinsic stains (4).Manufacturers claim that toothpaste and powders containing charcoal, which have recently become popular, have teethwhitening properties to prevent the recurrence of discoloration (5).
