Abstract
Introduction: The introduction of digital techniques in dentistry has led to advancements in various areas, including the evaluation and restoration of dental ceramics. One important aspect in this field is the study of color stability of dental ceramics, as it directly affects the esthetics and longevity of restorations. Purpose: Using a spectrophotometer, the study examines the effect of simulated gastric acid and thermocycling on color stability in various dental ceramics. Materials and Methods: In this study, 4 types of Monolithic CAD-CAM discs were milled, and immersed in artificial gastric acid solution monitored every 24 hours. Thermocycling was applied to all the groups and analyzed using a spectrophotometer. Results: VITA Enamic showed statistically significant color change. Conclusion: The present study demonstrated that the hybrid ceramics and leucite-reinforced ceramics suffered the most significant color changes after exposure to simulated gastric acid solution and thermocycling and showed that gastric acid with thermocycling changed the color of all types of dental ceramics.
