ABSTRACT

The virtue of the "perfect smile" is an easily achievable task with a better understanding of materials and diseases as well as advances in technology. Discoloured teeth can often be completely or partially corrected by whitening as it is conservative, non-invasive, and inexpensive, it is the treatment protocol of choice for the masses. Hydrogen and carbamide peroxides have been used successfully for many years; the teeth whitening technique has changed several times over the past century, and nearly 10 years before the new millennium, the technique was finally recognized by international regulatory agencies. It is important that dentists handle peroxides with a basic knowledge as it has been shown that the results will give satisfactory results. This technique depends on correctly diagnosing the stains, handling the substrates (enamel and dentin), and sensitivity. Dentists are exposed to a wide variety of teeth whitening techniques, products, and brands, and mild peroxide activation devices have been developed over the past two decades. The art is also currently subject to change depending on the effectiveness of the various light sources inactivating peroxide and their relationship to satisfactory end results. To achieve instant whitening without risk or relapse, innovative technologies and promising products have been developed. This article is intended to keep up to date with these new trends providing insight into the current clinical challenges of vital teeth whitening. The purpose of this literature review is to explain the determining factors influencing the successful end-results of the techniques and to provide an overview in order to make an evidence-based treatment decision.
