| Abstract | ||||
| Objective: Dental composites are considered one of the best direct restorative materials. The goal of this study was to evaluate how different staining solutions affected the color of monochromatic composite versus conventional composite. Materials and Methods: Thirty specimens, divided into two groups of fifteen each, were randomly assigned based on the type of composite. Group (O) was a supra-nano-hybrid monochromatic composite (omnichroma; Tockuyama), while group (C) was a conventional composite (Estelite α; Tockuyama). A spectrophotometer was used to record each specimen's color 24 hours after specimen preparation. The beverage solution that was used for storage was then utilized to subdivide the specimens into three subgroups, each consisting of five specimens. After that, the composite specimens were submerged in Pepsi, orange juice, and artificial saliva for a period of 14 days. A spectrophotometer was then used to measure the color change. Results: Statistical analysis showed statistical significance in color parameters (∆L, ∆a, ∆b) recorded the specimens in different beverage solutions in each group where p-value were <0.001*. The color change (∆E) mean values of the monochromatic composite group represented a statistically significant difference between the three beverage solutions used for storage where the p-value was <0.001*. However, there was no statistically significant difference recorded between the conventional and monochromatic composite groups. Conclusion: All the beverage solutions caused color change in both conventional and monochromatic composites. However, the orange juice solution caused significant discoloration in the composite specimens, which was unacceptable in comparison to other beverages. | ||||
