Sealant (any type) vs no treatment

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

Sealant may be more effective than no treatment for arrest or reversal of approximal carious lesions (RR 2.41, 95% CI 1.26 to 4.58; low certainty).

38% silver diamine fluoride 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)

38% SDF solution (applied annually) may not differ from 5% NaF varnish for arrest or reversal of root carious lesions (RR 0.64, 95% CI 0.04 to 9.66; very low certainty).

0.2% NaF mouthrinse + supervised toothbrushing vs Sealant

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 Sealant for arrest or reversal of occlusal carious lesions (RR 0.98, 95% CI 0.84 to 1.14; low certainty).

Sealant (any type) vs no treatment

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

Sealant was probably more effective than no treatment for arrest or reversal of occlusal carious lesions (RR 1.98, 95% CI 1.61 to 2.44; moderate certainty).
