Consecuencias del blanqueamiento dental en el complejo dentino pulpar.

Abstract

Tooth whitening is an aesthetic procedure based on the application of chemical agents that remove organic pigments from the teeth through an oxidation reaction. Despite its advantages and effectiveness, a major adverse effect is tooth sensitivity. The objective was to describe the consequences of tooth whitening on the pulpal dentine complex. A systematic review was carried out that included 20 articles published between 2018 and 2023, including 13 clinical trials. Materials such as 35% or 38% hydrogen peroxide and 16% or 10% carbamide peroxide are used for teeth whitening of vital teeth. Whitening can be done in the patient's office or at home. Tooth sensitivity after whitening may be a consequence of the mechanism of action of whitening agents during the oxidation process. The main measure to prevent tooth sensitivity after whitening is the use of desensitizing agents such as 5% potassium nitrate and sodium fluoride. Adding these desensitizing substances to whitening protocols may decrease the incidence of post whitening tooth sensitivity.
