Clareamento interno, terapia conservadora para casos de dentes não vitais escurecidos

Abstract

There is a perception that the number of darkened anterior teeth cases has been rising. In today’s odontology, professionals aim to be invasive as little as possible. Searching to corroborate with dentist surgeons' decision-making, this paper does a literature revision about intracoronary whitening, an effective and conservative therapy, acceptable either as a definitive treatment or the first step to treatments with indirect restorations. The therapy has variations in the technique, among those the walking bleach technique, the most divulged and tested one, with excellent results and color stability. Another variation is the inside-outside technique, a very safe alternative, but that requires more time, does not work on extremely severe cases, and needs a very collaborative patient. Another technique variation is the thermocatalytic, which has been falling in disuse due to its elevated risks of generating external radicular resorption and prolonged clinical time. Patients usually have little knowledge about intracoronary whitening as a therapy to treat non-vital darkened teeth, but the ones that have been treated with it have had their lives impacted by the significative increase in their aesthetic auto perception and psychosocial factors.
