Caries susceptibility, enamel demineralisation, erosion, or microhardness · Permanent teeth or extracted human teeth with artificial lesions
The laboratory studies did not find increased susceptibility to caries or enamel demineralisation, but no firm conclusions can be drawn because of high risk of bias.

GRADE not reported
Patient satisfaction (measured by patient satisfaction or aesthetic scales) · Patients with post-orthodontic white spot lesions and permanent dentition
In the single RCT, all bleached patients were satisfied with the aesthetic outcome, though the trial was at high risk of bias (ungraded).

Caries susceptibility, enamel demineralisation, erosion, or microhardness · Permanent teeth / enamel specimens (in vitro)
Low-quality in vitro evidence suggests that bleaching of permanent teeth does not increase susceptibility to caries, demineralisation or erosion (ungraded); the clinical question could not be answered because only in vitro studies were available.

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.
