The In Vitro Effect of Isotonic Sports Drinks on Color Variation and Thickness of A Material Used for Sport Mouthguards.

This in vitro study aimed to evaluate the effect of isotonic sports drinks (Gatorade) on color variation and thickness of ethylene-vinyl acetate (EVA). White thermoformed EVA blocks (n = 60) were prepared and randomly allocated into five groups (n = 12): reverse osmosis water (G1-control, transparent/colorless), isotonic passion fruit flavor (G2-yellow drink), isotonic citrus flavor (G3-orange drink), isotonic strawberry with passion fruit flavor (G4-red drink), and isotonic grape flavor (G5-purple drink). The specimens were submerged in their respective liquids/drinks for each group and incubated at 37°C for 28 consecutive days.
