Técnica de clareamento dentário combinada (mediata e imediata) em dente não vital traumatizado: relato de caso

Abstract

Tooth whitening is presented as a simple, economical, and effective way to enhance and restore the aesthetics of the patient's smile. Today, there are different techniques for performing whitening, which can be internal, external, or combined. The objective of this case report is to demonstrate the effectiveness of tooth whitening through the combined technique (mediate and immediate) in a non-vital tooth discolored as a result of trauma. The patient, male, 47 years old, came to the dental office with the main complaint of discomfort and dissatisfaction with the color of his teeth. The patient reported falls in childhood and onset of darkening 10 years ago; he reported pain in the tooth referred for 5 years and endodontic treatment in the same period. On intraoral examination, a darkening of the cited tooth was noted. A treatment plan was carried out, informing the patient about the planning and risks. The technique chosen was the combined mediate technique (“walking bleaching”, internal bleaching using sodium perborate with glycerin) and the immediate one (in-office, internal and external bleaching using 35% hydrogen peroxide). The combination of techniques proved to be effective and was able to successfully restore the patient's esthetics.
