Chlorophyll, Carotene, and Anthocyanin Effect on Color Change of Resin-Based Dental Materials: An in-Vitro Study

Background: The purpose of the present study was to evaluate the effect of chlorophyll, carotene, and anthocyanin-containing juices on color stability of resin-based dental materials. Methods: 192 disc-shaped specimens were prepared from six resin-based materials (universal, anterior, and flowable resin composites; self-curing polymethyl methacrylate (pmma), bis-acrylic composite, and computer-aided design/computer-aided manufacturing(CAD/CAM)- fabricated pmma). Divided groups were immersed in distilled water, spinach, carrot, and black mulberry juices (n=8). Color measurements were taken with a spectrophotometer before the immersions(T0), after one week(T1), and after four weeks(T2). The color differences (ΔE00) were used for statistical analysis. ANOVA was used to determine the effects of material, solution, and time on color change. Results: The highest color change was recorded for the CAD/CAM-fabricated pmma (ΔE=2.67) (p
