Non-invasive Treatment of Pulp-Calcified Teeth with External Bleaching
Objectives: To describe the aesthetic treatment with external bleaching using carbamide peroxide of teeth with an alteration in color appearance due to pulp canal obliteration after dental trauma.
Methods: Five patients demanding esthetic treatment of an anterior discolored tooth with history of trauma at least 10 years before were treated. All teeth exhibited a yellowish appearance and obliteration of the root canal without other alterations nor apical lesions. Patients manifested no response to thermal pulp testing. In all cases, color was selected before treatment with the color guide VITA toothguide 3D MASTER (VITA). Also digital photographs were taken (Canon EOS 60D) to assess fluorescence (INECSA SUPRA 230W DS 530-4 / 6/8) and with a croos polarization filter (Polar_eye Canon MT-24EX). External whitening was performed with a customized tray of 0.5mm thickness with windows cut out of the tray adjacent to the tooth to be treated. All patients used 16% carbamide peroxide (Prevdent nHApTM repair Whithening) during night with a minimum of 6 hours. Changes in color were clinically assessed every two weeks.
Results: All teeth treated showed an improvement in their aesthetic appearance with a decrease in saturation and an increase in opacity that was perceived as successful for the patients without requiring other treatments.
Conclusions: At-home external whitening with 16% carbamide peroxide is an efficient and minimally invasive solution to reduce saturation in teeth with pulp canal obliteration due to trauma.
