Figure Lengend Snippet: The colour change of resin composites following immersion in dye solutions. The solid red line represents the visually perceptible threshold (ΔE 00 = 0.8), while the dashed red line indicates the clinically acceptable threshold for colour change (ΔE 00 = 1.8). Bar graphs below the blue lines represent groups that showed no statistically significant differences in colour change.

Figure Lengend Snippet: Visual representation of colour changes in resin composites in Br (Brilliant Blue) over time. Each row corresponds to a different resin composite, and columns represent three time points: baseline (T0), after dye immersion (T1), and after treatment with whitening mouthwash (T2). The resin composites included are Charisma Smart (CHR), Estelite ∑ Quick (EST), One Bulk Fill Restorative (OBF), RubyFlow (RBF), Spectra STHV (SPC), and Ultimate Universal Restorative (ULT). This visualization highlights the impact of staining and subsequent whitening treatment on resin composite colour stability.

Figure Lengend Snippet: Changes in the dental whiteness index (WI D ) of the resin composites OBF, RBF, SPC, CHR, EST, and ULT across the three evaluation periods: baseline (T0), after staining (T1), and after whitening (T2). Each panel represents a single composite, and coloured lines indicate the different staining solutions (Brilliant Blue, Ponceau 4R, Carmoisine, Sunset Yellow, Tartrazin, and Control). Higher WI D values indicate greater perceived whiteness, whereas lower values reflect increased discolouration.
