Laser/light-activated bleaching vs Conventional (non-laser) bleaching with hydrogen or carbamide peroxide
Enamel microhardness / caries susceptibility · Permanent teeth / enamel specimens (in vitro)
Low-quality in vitro evidence found no support for adding lasers to in-office bleaching; laser-activated bleaching did not appear to affect enamel microhardness or caries risk versus conventional bleaching (ungraded).
