The coloration of teeth is an
event that depends on many factors according to their localization and
etiology. In cases of internal staining, dentin may be affected alone, staining
may occur that only concern the enamel or involve both tissues. External discoloration
occurs when prophylactic cleaning is not done adequately. The process of
removing the discolorations caused by the application of agents that can be
chemically or physically effective on the colored teeth is called
"whitening". Oral care products that are put on the market today are
designed for the prevention of tooth decay and gum diseases as well as
whitening teeth. Frequently used whitening materials in oral care products;
abrasives, anti-redeposition agents, calcium phosphates, colorants, enzyme /
proteases, peroxides, polyaspartates, surfactants and borates. Peroxides are
highly effective agents in office bleaching, but they can cause side effects
such as damage to the enamel and dentin organic matrix and tooth sensitivity.
The availability of abrasives in whitening oral care products is limited by the
potential tooth wear, especially in the use of toothpastes with high RDA
values. The in vivo effect of other bleaching materials is often uncertain due
to the lack of placebo-controlled clinical studies. The purpose of this review
is to classify commonly used bleaching agents according to their mechanism of
action and to summarize and discuss their effects from both a clinical and
chemical perspective.
