Color Stability of Bioactive Restorative Material vs Nanohybrid Resin Composite: An In Vitro Study.

Aim: This study aimed to assess the color stability of bioactive restorative materials vs nanohybrid resin composites after 3 months of immersion in three frequently consumed beverages.
Materials and Methods: Thirty disk-shaped specimens of Giomer dental restorative material (Shofu, Japan) and nanohybrid resin composite (Tokuyama, Japan) were performed using a Teflon mold. Super-Snap system (Shofu, Japan) was utilized to finish and polish the specimens to be preserved for 24 hours in distilled water at 37°C. The samples had been divided into three subgroups (Coffee, tea, Pepsi) ( n = 5). The initially displayed color measurements of the samples were performed using a spectrophotometer (VITA Easyshade® V). After 7 days, 30 days, and 90 days, color measurements were repeated, and the E of each sample was estimated. E of each sample was calculated.
Results: The Giomer group showed statistically significant higher E values than the nanohybrid resin composite where the p -value was ≤0.0001. Tea subgroup showed the highest statistically significant E values in both groups where the p -value was ≤ 0.0001. The highest statistically significant color change was recorded at 3 months.
Conclusion: The color of bioactive restorative material is less stable if compared with nanohybrid resin composite.
Clinical Significance: As tea and coffee are popular beverages, particularly in Middle Eastern nations, dentists must advise patients about the color change of resin restorations. Patients are advised to brush their teeth immediately after consuming these beverages. How to cite this article: Saber EH, Abielhassan MH, Abed YA, et al .
