Group with no desensitizing treatment. Prior to bleaching therapy, a water-soluble placebo gel, with non-active agent will be applied to dental vestibular surfaces. After bleaching therapy, the LASER tip will be positioned in two points (apical and cervical), without light emission (placebo).
Group treated with placebo gel before bleaching and with LLLT after in-office bleaching.
Group treated with desensitizing gel before bleaching and after in-office bleaching, the LASER tip will be positioned in two points (apical and cervical), without light emission (placebo).
