1.23% APF gel vs Fluoride varnish

Arrest or reversal of noncavitated occlusal carious lesions · Children and adults with noncavitated carious lesions on occlusal surfaces (primary and permanent teeth)

1.23% APF gel may not differ from 5% NaF varnish for arrest or reversal of occlusal carious lesions (RR 1.08, 95% CI 0.83 to 1.4; low certainty).

Placebo rinse vs Pre-treatment (baseline, same group)

Streptococcus mutans count · Medically healthy individuals (adults and children, 6-60 years)

0.2% NaF mouthrinse + supervised toothbrushing vs Fluoride varnish

Arrest or reversal of noncavitated occlusal carious lesions · Children and adults with noncavitated carious lesions on occlusal surfaces (primary and permanent teeth)

0.2% NaF mouthrinse + supervised toothbrushing may not differ from 5% NaF varnish for arrest or reversal of occlusal carious lesions (RR 0.99, 95% CI 0.84 to 1.15; low certainty).

1 finding from 1 review

Fluoride varnish vs no treatment

Arrest or reversal of noncavitated and cavitated root carious lesions · Adults (including institutionalized/older adults) with noncavitated and cavitated carious lesions on root surfaces (permanent teeth)

5% NaF varnish may not differ from no treatment for arrest or reversal of root carious lesions (RR 2.96, 95% CI 0.27 to 32.26; very low certainty).

Intervention not reported

Dental caries prevalence · Children (<12 years) and adolescents (12-18 years) with type 1 diabetes

The pooled prevalence of dental caries among children and adolescents with type 1 diabetes was 67% (95% CI 0.56 to 0.77), with high heterogeneity (I2=83%); certainty not graded.

1% chlorhexidine + 1% thymol varnish vs Fluoride varnish

Arrest or reversal of noncavitated and cavitated root carious lesions · Adults (including institutionalized/older adults) with noncavitated and cavitated carious lesions on root surfaces (permanent teeth)

1% chlorhexidine + 1% thymol varnish may not differ from 5% NaF varnish for arrest or reversal of root carious lesions (RR 0.57, 95% CI 0.04 to 8.69; very low certainty).

1 finding from 1 review

Oral-health promotion programs (OHPPs): community-based oral-health education/training, supervised toothbrushing with fluoride toothpaste and topical fluoride, dental screening, and dietary advice vs No oral-health promotion program, or a differing (usual-care) action under similar conditions

DMFT/DMFS index (dental caries experience) · Children with dental caries

Oral-health promotion programs were associated with markedly lower odds of DMFT/S in children (OR 0.19, 95% CI 0.10 to 0.39; ungraded, very high heterogeneity I2=98.5%).
