Usage:
1. Use the top row of teeth on the form guide (1M1, 2M1, 3M1, 4M1, 5M1) to determine the luminance level and simply decide whether the teeth on the form guide match or not
2. following the same principle, the samples were spread out like a fan to determine the color saturation (hue)
3. check to see if the natural teeth are more yellow (L) or red (R) than the Toothguide sample. With these three steps, you can determine the color of natural teeth faster and more reliably!
