The practice of designating bleaching stages and sequences using a symbolic shorthand has evolved through the years.

Adherence is urged to facilitate clarity in communication. To accommodate new developments in the rapidly changing field of bleaching process technology, additions, variations, or exceptions will most certainly be required. In such an event, the symbolic representation should be made very clear early in the corresponding presentation.
