Cold atmospheric plasma for bleaching endodontically treated tooth: a new clinical approach

The most commonly used bleaching agents contain different concentrations of hydrogen peroxide and carbamide peroxide. In the present case, the bleaching procedure was performed using an induced field of cold atmospheric plasma, obtained from dielectric barrier discharge. The therapeutic effect of the device used in the clinical procedure is based on floating elec- trode dielectric barrier discharge, in which the glass electrode functions as the primary electrode, while the therapeutic area, which in this case is the tooth, represents the secondary elec- trode. A periodontal (PA) probe is a glass tube filled with a no- ble gas, which generates an electrical discharge in the gap between the tip of the electrode surface and the therapeutic area, thus producing reactive oxygen species. Bleaching with only the cold atmospheric plasma bleaching technique, with- out any conventional bleaching agents, was performed suc- cessfully for an endodontically treated tooth. The cold atmo- spheric plasma bleaching technique, which could be a novel approach for the bleaching of non- vital teeth, provides good clinical results and is safe for clinical use.
