Case #280 : Tooth whitening

History of the present complaint: Aesthetically disturbing severely discoloured tooth UR1.
Radiographic examination: 11 Apicectomy, 11 & 21 apical root resorption.
Differential diagnosis of tooth discolouration: Intra/extracoronal amalgam- & intracoronal GP- induced discolouration.
Clinical intervention: External in-office bleaching technique as a supplement to the walking bleaching technique was repeated under the first 2 visits
Scientific evidence: The evidence from the literature suggest that the management of discoloured endodontically treated teeth by means of combined intracoronal bleaching technique bleaching is a valid treatment modality in terms of safety, efficacy, time efficiency and aesthetic outcome (Goldstein et al 1989, Amato et al. 2006). The result from the 16-year prospective study by Amato et al. (2006) also demonstrated the chromatic stability of nonvital discoloured teeth, when subjected to the combined intracoronal bleaching technique. The clinical outcome has vastly improved the poor appearance of the upper right central incisor. Further follow-up of chromatic stability and shade recording is required.
