Atmospheric Pressure Cold Plasma (APCP) showed good effects in tooth whitening. However, the longevity of tooth whitening using different Hydrogen Peroxide (HP) concentrations with APCP has not been reported. Therefore, the aim of this study was to determine the longevity of tooth whitening effect and surface roughness using APCP by high or low concentrations of HP. Specimens were treated with different HP agent and APCP for 20 minutes. After treatment, we were evaluated the color of the specimens. The specimens were then put into distilled water for different time periods. The specimenswere re-evaluated.The result ofthis study,the longevity oftoothwhitening effect ofAPCPwith lowconcentration of HP was not different from that of APCP with high concentration of HP. In addition, the two HP concentrations did not cause any changes to the enamel surface over time.
