One-year follow-up of non-vital discolored teeth after bleaching with an association of techniques: a case report.Gen Dent. 2007 Nov; 55(7):676-82; quiz 683-4, 712.GD
Patient demand for esthetic procedures and the trend for non-invasive dental treatment have led to the development of different materials and whitening techniques that are capable of re-establishing a patient's smile without affecting dental structure. Numerous potential factors may cause the discoloration of pulpless teeth. A simple and time-saving method for bleaching discolored root-filled teeth combines intracoronal and extracoronal bleaching with 35% hydrogen peroxide and a procedure known as the walking bleach technique, a conservative treatment that restores esthetics to darkened and stained non-vital teeth. This article presents a case report that used this technique and examines the effects of this treatment after one year.
