In order to determine the susceptibility of nanohybrid composite resins to discoloration by turmeric, we immersed specimens in 0.015%, 0.15%, 1.5%, and 15% turmeric solutions for 24 and 48 hours and then measured the color changes using a Vita Easyshade instrument. Differences in color intensities were then identified using Kruskal-Wallis and Spearman's tests. Immersion of nanohybrid composite resins in turmeric solutions decreased brightness (L∗) and increased chroma a∗ and chroma b∗ values, leading to significant total color changes (ΔE). Moreover, higher turmeric concentrations were correlated with increases in the reddish-yellow staining of nanohybrid composite resins.
