    The degree of pigmentation of teeth with composite resin and acrylic resin was determined in in vitro tests influenced by carbonated beverages. The total sample consisted of 32 teeth, divided into two groups of 16 elements, made of composite resins and acrylic resins. The study was longitudinal and experimental, comparing the degree of pigmentation due to exposure to carbonated beverages at 30 and 60 minutes. Statistical analysis was performed using Pearson's statistical test. The variations showed an initial average color value of composite resin and Coca-Cola of 92.3375, for Fanta® 92.4000; acrylic resin with Fanta® 79.9875, Coca-Cola® 81.6000. After 30 minutes of exposure, composite resin with Coca-Cola® had a value of 87.8125, Fanta® 91.5125; acrylic resin with Fanta® 85.5750, acrylic resin with Coca-Cola® 91.0125. After 60 minutes, composite resin with Coca-Cola® had a mean value of 80.4750, with Fanta® 81.8500, acrylic resin with Fanta® 81.4875, acrylic resin with Coca-Cola® 82.6000. Conclusion: Carbonated beverages influence the degree of pigmentation of teeth with composite and acrylic resins.
