The purpose of this study was to evaluate the tooth bleaching effect by the use of nonthermal atmospheric pressure plasma supplied by humid air(humid air plasma) along with 5 %, 15 %, and 35 % of hydrogen peroxide(HP). A total number of 90 stained teeth were divided into 9 groups(n=10) and treated in different bleaching conditions: only HP, HP with air plasma, and HP with humid air plasma. Color changes(ΔE ) were measured after three consecutive bleaching using spectrophotometer and National Bureau of Standards systems. One-way ANOVA combined with post-hoc test using Tukey’s method was performed for the statistical analysis. The results showed that final ΔE values increased significantly in all groups(p<0.05), indicating the effective tooth bleaching. The most significant color changes were noted on samples treated with 15 % HP humid air plasma, 35 % HP air plasma and 35 % HP humid air plasma(p<0.05), but there were no significant differences amongst them(p>0.05). This study suggested that tooth treated by HP with humid air plasma is more effective for tooth bleaching compared to only HP and HP with air plasma. Lastly, it is concluded that using 15 % HP in conjunction with humid air plasma is more safe compared to simply using 35 % HP.
