Extended dental bleaching procedure: A case report

Abstract

Dental bleaching offers a conservative, simplified, and low cost approach to change the color of discoloured teeth. Current bleaching techniques include a dentist-prescribed in-office technique, an at-home applied technique, or a combination of both. The pigments oxidation is responsible for tooth bleaching and can be carried out with two different products; carbamide peroxide and hydrogen peroxide. Usually the protocols for at-home bleaching include custom trays use and bleaching agents in lower concentrations. Carbamide peroxide is currently found in low concentrations for at-home technique and high concentrations for in-office technique are available. On the other hand, hydrogen peroxide was typically indicated in high concentrations for in-office bleaching but nowadays is available in low concentrations for at-home protocols. This paper describes clinical case performed with bleaching system technique by the use of hydrogen peroxide bleaching agent available in the market. The extended in office vital bleaching was effective with 35% hydrogen peroxide with satisfactory results no post treatment complications.
