Summary: The purpose of the study is to evaluate the effect of various laser techniques for
bleaching teeth in office vital whitening. Hydrogen peroxide and carbamide peroxide were used
to receive chemical action of bleaching process. Extracted upper central incisors were exposed
to laser radiation. Four different laser systems were applied to accelerate the speed of process.
Nikon Labophot (Japan) microscopewas used for color change determination.Scanning electron
microscope Jeol (Japan) checked the quality of surface structure. The Nd:YAG laser SHG; CTE:
YAG laser had no bleaching effect. Nd:YAG laser, waveguide 1,06 µm radiation destroyed the
surface of tooth. Alexandrite laser application was considered an elective process to decrease
the time of bleaching without the surface modification.
