Does the thickness of universal-shade composites affect the ability to reflect the color of background dentin?

Original language description

The recently introduced resin composites with a universal shade are claimed to match any tooth color. In this study, it was examined how composite thickness affects the color adjustment of conventional and universal-shade composites to background dentin. Thirty sound human central incisors of various shade were used, and color differences between their intact labial surfaces, exposed dentin surfaces and composite restorations (thickness 1-3 mm) were evaluated. In addition, the translucency, light transmission characteristics, and spectral reflectance of the composites were measured. The results showed that universal-shade composites outperformed conventional composites of A2 shade in the adjustment of hue and chroma (p&lt;0.05) but not in lightness (p&gt;0.05). The color adjustment potential of all composites significantly decreased as their thickness increased (p&lt;0.05). The effect of thickness on Omnichroma and Omnichroma Flow was less marked, presumably because of their higher translucency (p&lt;0.05) and structural coloration which induces light reflectance in the yellow-to-red range.
