Abstract
Color matching and stability are the essential considerations in restorative dentistry, as they contribute to the longevity and esthetic appeal of the restorations. Composites with nanoparticles and more filler content are anticipated to be more color-stable. The aim of the study was to assess and contrast the color stability of esthetic restoration materials following exposure to various antioxidant beverages. A Class V cavity was prepared on the buccal surface of 40 maxillary premolars. The specimens were divided into two groups: microhybrid (MH) and nanohybrid (NH) composite. The baseline color of each tooth sample was measured and then, the samples were categorized into four subgroups based on the immersion solution (pomegranate juice, beetroot juice, black plum juice, and distilled water) and evaluated on day 1, day 7, day 14, and day 21 using a spectrophotometer-based on CIE L*a*b* color scale. For spectrophotometer analysis, CIE XYZ data were obtained and converted to CIELAB. The samples mean difference in ΔE values before and after being immersed in various beverages. The data were statistically analyzed using an independent t-test and one-way analysis of variance. MH and NH composite materials showed color change after being exposed to the test beverages. MH composite causes more color change than NH composite at all-time intervals. Black plum showed the greatest discoloration in both composites.
