Exercise No. 374
Subject Code: 781
The 15 questions for this exercise are based on the article, In vitro evaluation of calcium and phosphorus concentrations in enamel submitted to an in-office bleaching gel treatment containing calcium, on pages 52-56. This exercise was developed by Kim Capehart, DDS, MBA, PhD(c), and Jean J. Carlson, DDS, FAGD, in association with the General Dentistry Self-Instruction committee.
Reading the article and successfully completing this exercise will enable you to:
- understand the chemistry of hydrogen peroxide–based (HP) in-office bleaching systems with (WCa) and without (W) calcium gluconate;
- identify the advantages and disadvantages of adding calcium and phosphorus to bleaching systems; and
- recognize the effects of in-office bleaching systems on enamel.
