This clinical study was carried out to investigate and evaluate the effect of using a titanium dioxide photocatalyst in conjunction with different concentrations of hydrogen peroxide bleaching gels on the color change tooth sensitivity and surface roughness of enamel . Results the current study revealed a statistically significant change in both {u2206}E and Y values after bleaching with the 32% concentration of hydrogen peroxide in most of the groups tested, while the lower concentration mostly lacked such effect in the adopted blaching time
