External bleaching for teeth with dystrophic calcification of the pulp: clinical case report

Abstract

This paper presents an alternative for the treatment of teeth with dystrophic calcification of the pulp. Calcification is generally accompanied by chromatic alterations of the tooth. Traditionally, these alterations were treated with invasive restorative treatments like dental facets and crowns. External bleaching is an alternative that makes a conservative esthetic and biological solution possible, especially in cases in which it is difficult to gain access to the root canals system. This clinical case presents a patient with color alteration in the top left central incisor decurring from total dystrophic calcification of coronary and root pulp caused by a trauma. The treatment encompassed thirty days of home supervised bleaching by the use of a tray with carbamide peroxide gel at 16% plus two in-office bleaching sessions with hydrogen peroxide at 35% to solve the intense color saturation in the cervical portion of the tooth.
