The study on color space of the VINTAGE & UNIBOND standard color / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To research the color space of the standard color board, guide the clinic work of color match, and establish an foundation for deeper researching.</p><p><b>METHODS</b>Through taking analysis of reflecting spectrum and spectral tristimulus, each parameter of the color on standard board was found out. The color difference between border upon colors on board was worked out through matching the color parameters. The number of color space between each border upon color on standard color board, divided by deltaE = 1.5, was found.</p><p><b>RESULTS</b>The number of color space between each border upon color was 3-6. The color space was bigger in group B, but smaller in group D. The color space was bigger in high lightness area, but smaller in low lightness area.</p><p><b>CONCLUSION</b>Some color space has been found between standard color borders of VINTAGE and UNIBOND. Color of natural teeth is unable to be completely included into standard color border, especially in clinical care.</p>
