Laser enamel preparation alone (Er,Cr:YSGG or CO2 laser) vs Acid-etching (phosphoric acid)

Development of >=1 new carious lesion (caries incidence) · Caries-free children to young adults with premolars/molars requiring pit-and-fissure sealants

In the single study reporting it, caries incidence was 0% in both the laser-alone and acid-etching groups (ungraded, single study).

Acceptability · Caries-free children to young adults with premolars/molars requiring pit-and-fissure sealants

Both laser and acid-etching preparation were well accepted by patients (VAS, P = 1.000; ungraded, single study).

Laser enamel preparation alone (Er,Cr:YSGG or CO2 laser) vs Acid-etching (phosphoric acid)

Clinical (chair-side) time · Caries-free children to young adults with premolars/molars requiring pit-and-fissure sealants

Laser conditioning was reported to take less chair-side time than acid-etching in the studies that measured it, but times were not pooled (ungraded, narrative).

Sealant retention rate (completely retained) · Caries-free children to young adults with premolars/molars requiring pit-and-fissure sealants

At 18 months, laser preparation alone did not differ significantly from acid-etching for sealant retention (OR 0.82, 95% CI 0.23 to 2.85; ungraded, single study, high risk of bias).
