Clinical Trial: 450 nm Blue Diode Laser Versus Blue LED for In-Office Tooth Bleaching

U.S., Oct. 14 -- ClinicalTrials.gov registry received information related to the study (NCT07870317) titled '450 nm Blue Diode Laser Versus Blue LED for In-Office Tooth Bleaching' on Oct. 06.

Brief Summary: Tooth discoloration is commonly managed using in-office dental bleaching. This randomized clinical trial compared the efficacy and safety of activating the same 35% hydrogen peroxide bleaching gel with either a 450 nm blue diode laser or a conventional blue light-emitting diode lamp. Forty participants aged 18 to 25 years were randomly assigned in a 1:1 ratio to one of the two interventions. The primary outcome was postoperative tooth hypersensitivity immediately after treatment. Secondary outcomes included immediate tooth-color change,...
