Tooth bleaching (carbamide or hydrogen peroxide; home and/or in-office) vs No bleaching (untreated control)
Colour change / camouflage of white spot lesions (reduction of colour disparity between carious and sound enamel) · Permanent teeth with post-orthodontic white spot lesions (orthodontic patients and in vitro enamel specimens)
Bleaching may diminish colour disparities and camouflage post-orthodontic white spot lesions, but the certainty of the evidence is very low; the findings could neither support nor refute bleaching.
