Bleaching gel with added remineralising agent (fluoride, calcium, or CPP-ACP) vs Bleaching alone (no remineralising agent)

Whitening (bleaching) efficacy · Demineralised / white-spot-lesion enamel (in vitro specimens)

Low-quality in vitro evidence indicates that adding fluoride or other remineralising agents does not impair the whitening/bleaching effect (ungraded).

Bleaching gel with added remineralising agent (fluoride, calcium, or CPP-ACP) vs Bleaching alone (no remineralising agent)

Enamel mineral loss / remineralisation · Demineralised / white-spot-lesion enamel (in vitro specimens)

Low-quality in vitro evidence indicates that adding fluoride, calcium or CPP-ACP to bleaching agents can reduce enamel mineral loss (ungraded).

Er:YAG laser preparation combined with acid-etching vs Acid-etching (phosphoric acid)

Sealant retention rate (completely retained) · Children with permanent molars requiring pit-and-fissure sealants

At 12 months, Er:YAG laser combined with acid-etching significantly improved sealant retention versus acid-etching alone (OR 0.39, 95% CI 0.19 to 0.80, favouring laser+acid; ungraded, single study).

Er:YAG laser preparation combined with acid-etching vs Acid-etching (phosphoric acid)

Development of >=1 new carious lesion (caries incidence) · Children (high caries risk) with permanent molars requiring pit-and-fissure sealants

Caries incidence was 10% with laser-plus-acid versus 22% with acid-etching at 18 months, a non-significant difference (ungraded, single study).
