Summary:
One of the most conservative treatment methods to correct or improve the colorof teeth is bleaching. This study describes the preclinical experience with laser-activatedbleaching agent for treatment discolored teeth. The study is comparing three laser systems,halogen-light unit and chemical action agents to check the time and quality of bleaching process.The purpose of the study is to evaluate the effect of various laser techniques for bleaching teethin office vital whitening. The method of chemical oxidation results in a 2–3 shade change in onetreatment. The halogen-light units, Alexandrite laser (750 nm), and Er:YAG received the sameeffect and shorter time of bleaching process. The local overheating of chemical bleaching agentwas visible after Er:YAG laser activation. Slight surface modification after bleaching processwas detected in SEM. It was found that selective laser radiation can decrease the time ofbleaching without the surface modification.
