Aspectos do clareamento sobre a polpa

Abstract

Tooth whitening is one of the main procedures requested by those who want a more aesthetic smile, given that darkened teeth do not have a youthful appearance, and that this procedure is conservative and effective when compared to other aesthetic procedures that require wear and tear. are very invasive, despite having some deleterious effects that can range from mild sensitivity to pulp necrosis. The whitening techniques are: in-office, homemade and mixed and their main difference is linked to the time and concentration of the gels used. The aim of this study was to review dental bleaching techniques in vital teeth, focusing on which technique causes less damage to pulp tissue. Scientific articles on the subject were searched for this literary review. Studies prove that the type of gel used and its concentration, pH and exposure time are directly linked to the increase in the amount of peroxide inside the pulp chamber. Techniques that use lower concentration gels, have a more alkaline pH and shorter exposure time showed a better result when considering tooth sensitivity and other adverse effects on the pulp. Another observation analyzed was the insertion of desensitizing agents and nanoparticles in the gels, which concomitantly coincided with the reduction of adverse effects. And the use of light coincidentally increased the temperature of the pulp chamber when associated with bleaching gels. In this way, the homemade technique brings the best result in color stability and with the least deleterious effect and the use of low concentration gels as well.
