Sensibilidad post-operatoria como efecto adverso del blanqueamiento en diente vitales

Abstract

Introduction: Teeth whitening is one of the most requested dental procedures. It is based on a chemical process of oxidation-reduction seeking for the clearance of pigmentation generated on the enamel. There are several techniques used, depending on the concentration of peroxides, the chemical or light activation, such procedures generate tooth sensitivity. The objective of this systematic review is to refer the adverse reactions of the tooth whitening in terms of sensitivity. Materials and methods. The articles used in this systematic review are randomized, electronically searched between 2004 and 2013 in different databases. Results from 3282 articles found, 30 articles were selected for inclusion in the review, as they met the established criteria. After selecting the final articles for the review, a methodological evaluation of these became, through which it was found the level of evidence and grade of recommendation according to the Caspe guide. Conclusion. Taking into account the good 'evidence' found it was concluded that: tooth sensitivity is the most common side effect in tooth whitening. The home whitening generated less sensitivity due to its low concentration of peroxide compared to the in-office whitening.
