Abstract
The aim of the present study was to investigate the combinational effect of atmospheric pressure cold plasma and hydrogen Peroxide bleaching agents on external tooth bleaching. Teeth were randomly divided into three groups: 15% hydrogen peroxide+Air flow plasma (Air plasma), 15% hydrogen peroxide+ Nitrogen plasma (Nitrogen plasma) and 15% hydrogen peroxide only (control). The color change of the teeth was evaluated before treatment, 10 min and 20 min after treatment using a spectrophotometer. Surface roughness(Ra) was measured by profilometer at before and after 20 min treatment. There was significant differences in color change between the plasma treated groups and control (p<0.05), there being no significant difference between the two plasma groups (p>0.05). There were no significant differences in surface roughness among all group (p>0.05). Hence, we conclude that the atmospheric pressure cold plasma treatment may accelerates the teeth bleaching process no matter which kind of gases (Air plasma and Nitrogen plasma) is used.
