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).

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).

Durmus 2017 (Er:YAG laser+acid vs acid-etching): caries incidence 10% (n=8) in the laser-plus-acid group vs 22% (n=18) in the acid-etching group at 18 months; difference not statistically significant (P > 0.05).

Dental anxiety (subjective and objective scores) · Children (ages 6-12) receiving pit-and-fissure sealants

Er:YAG laser preparation added to acid-etching did not increase children's dental anxiety versus acid-etching alone (P > 0.05; ungraded, single study).
