Prenatal vitamin D level ≤50 nmol/L vs Adequate prenatal vitamin D (sufficient maternal 25(OH)D)

Dental caries · Children aged 2 to 8 years

The review reported a lower odds ratio at maternal prenatal vitamin D ≤50 nmol/L than at ≤35 nmol/L, without a numeric value in the available sources.

Preterm birth (<37 weeks gestation) vs Full-term birth (37 weeks or more gestation)

Early childhood caries (ECC) · Children aged 6 years or younger (preschool children)

In children aged 3 years or younger, preterm birth was not associated with early childhood caries (OR 0.90, 95% CI 0.59 to 1.37); certainty not graded.

Laser enamel preparation (with or without acid-etching) vs Acid-etching (phosphoric acid)

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

No adverse events were reported in any included study (ungraded, narrative).

Preformed metal crown (fitted using the Hall Technique) vs Preformed metal crown (fitted using a conventional technique)

Outcome not reported · Children with decayed primary molar teeth

The review found no eligible studies for this question.

1 finding from 1 review
  • None of the included studies compared the effectiveness or safety of the Hall Technique versus the conventional technique of fitting a crown. No RCT evidence found.

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).

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

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).

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

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).
