Colorimetric Comparison of Two Kinds of VITA Shade Guides

Abstract:

Our aim was to analyze the color ranges of two kinds of Vita shade guides and compare these color ranges with that of Chinese teeth. To do this, the color range and ordering of the Vita Classical and Vita 3D-Master shade guides were measured and analyzed with a MINOLTA CM-2600d spectrophotometer under a D65 standard source. The CIE-1976-L* a* b* system was adopted. We found that compared with the Vita Classical shade guide, Vita 3D Master covers a greater range of a*, and b*, which includes more yellow -reddish and more saturated color tabs. The range of L* extends further towards darker values, while in higher range the two guides are the same. Comparing these color ranges with that of Chinese teeth, the Vita 3D-Master is preferred to the Vita Classical Guide. Because of the larger range of teeth-colors covered, and the logical arrangement, we recommend the clinical use of the Vita 3D-Master shade guide.
