This work attempts to determine the best index for measuring the whiteness of human teeth. For this the classifications obtained from various whiteness indices have been compared, using Spearman's correlation coefficient, with the responses of 20 observers judging a group of 20 samples of porcelain teeth. The index which gives the best results is that proposed by the CIE, WIC, although the Z% and the CIELAB color difference ΔE are also adequate for measuring the whiteness of human teeth. © 1993 John Wiley & Sons, Inc.
