Resins are synthetic materials that help restore dental pieces, whether due to fractures or cavities, but over time they change color due to our eating habits. In this research, two types of resins were used: Tetric N Ceram (Ivoclar) and Filtek Z350 (3M), which were immersed in coffee and Coca-Cola for a period of 15 days. The results showed that the resins immersed in coffee underwent a greater color change compared to those immersed in Coca-Cola. It was found that both resins underwent almost the same amount of color change, with minimal differences between the two.

In vitro study on the color stability of two dental resins (Omnichroma Y Z350XT) against three pigmenting beverages (coffee, coca cola and chicha morada) most consumed by the population of Lima. Lima Peru. 2021

The aim of this study was to compare the color stability of two dental resins exposed to three commonly consumed staining beverages in the population of Lima. Two resins were used for aesthetic zone restorations (Omnichroma and Z350XT), and three staining beverages (coffee, Coca-Cola, and purple corn drink). The resins were formed into discs with a diameter of 10 mm and a thickness of 2 mm, using a mold where increments of 2 mm of resin were added until the required disc dimensions were achieved. Once the resin discs were made, the initial color was checked using the Vita classical color guide, and this information was recorded on the data collection sheet. In total, 30 discs of each resin type were made, with 10 discs for each beverage studied, for a total of 60 discs. The beverages were then prepared in separate jars, with 40 ml of each substance poured into a different jar. The resin discs were submerged in the beverages for 15 days, with the beverage being replaced after 7 days with the same substance. After 15 days, the discs were removed, rinsed, and dried, and the color was measured again, with the data recorded on the data sheet.
