There are more and more advertisements for whitening teeth, and some patients who come to the clinic complain that their teeth don’t seem to whiten even though they use the products advertised.
In fact, teeth are not white, can not be observed only by the naked eye.
According to Jennyshen, m.d., of Los Angeles state university dentistry, dentists use the internationally used VITA colorimetric plate as the tooth colorimetric standard to diagnose patients with tooth colorimetric staining.
The order of professional tooth whitening colorimetry from light to deep: 1¡úB1, 2¡úA1, 3¡úB2, 4¡úD2, 5¡úA2, 6¡úC1, 7¡úC2, 8¡úD3, 9¡úA3, 10¡úD4, 11¡úB3, 12¡úA3.5, 13¡úB4, 14¡úC3, 15¡úA4, 16¡úC4.
The letters represent the patient’s propensity for tooth coloration: A for reddish-brown;
B for red and yellow;
C is for gray;
D is for red and gray.
The degree of discoloration is represented by a number, and the higher the number, the more skewed the color.
For example, if the patient’s tooth color is C3, it means that the patient’s teeth are moderate tetracycline teeth, and if it is A3.5, it means that the patient’s teeth are clearly yellow.
In professional tooth whitening treatment, comparison of tooth color according to VITA before and after surgery can provide an objective and true evaluation of the whitening effect.

For example, the patient’s teeth were D4 before the use of whitening scheme, and changed to B2 after the treatment, indicating that the whitening effect obtained by the patient is 8 color levels.
