hay david,
     i dont know where to start but wat i know is that you can't measure 
whiteness from anything. Or the only method you can measure whiteness is 
shade card, which you can get from a dentist or from any dental lab. but 
that really will not help in measuring the effectiveness of the toothpaste 
in removing stains.
thanking you
