Tooth whitening by a direct-current cold atmospheric-pressure air plasma micro jet assisted with a gel containing NO H2O2

摘要

Aesthetics of teeth, including tooth color, is of great importance to people. Conventional clinical tooth-whitening treatments are mainly based on hydrogen peroxide (H2O2), while some studies demonstrate that the bleaching process can be accelerated when enhanced by heat or light (laser, cold light). The dependence on H2O2 may lead to sensitivity or different degree of injury on soft tissue. As the forth material state, non-thermal plasmas have recently attracted much interest in biomedicine. Studies confirm that nonthermal plasma is effective in accelerating the tooth whitening process.
