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).

Residence in weakly contaminated area (approx. 1-5 Ci/km2) vs Residence in non-contaminated (non-exposed) area (<1 Ci/km2)

Dental caries · Children aged 12-15 years (adolescents)

In adolescents (12-15 y) from weakly contaminated areas, individual studies mostly reported higher DMFT/dmft in exposed children but with wide variation; the review did not pool the data (ungraded).

Longitudinal follow-up over time (natural caries progression; no assigned intervention) vs Within-cohort change from baseline to follow-up (>=3 y)

Annual increment in DMFT (permanent dentition) · Children and adolescents (permanent dentition, D3, up to 21 y), Western or comparable populations

In the permanent dentition, the annual DMFT increment ranged from 0.06 to 0.73 across 14 studies, and was higher where baseline caries experience was higher (descriptive range; ungraded).

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

Caries prevalence was lowest among those with good metabolic control at 47% (95% CI 0.30 to 0.64); certainty not graded.

38% silver diamine fluoride vs placebo

Root carious lesions arrest · Older adults with root carious lesions (exposed root surfaces)

One review reported SDF may reduce progression of root caries, with no numeric result (ungraded).

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 aged 0-12 years in the United Kingdom

In UK studies, OHPPs were associated with lower DMFT/S (OR 0.04, 95% CI 0.00 to 0.58; ungraded).

Intervention not reported

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

Caries prevalence in European studies was 57% (95% CI 0.41 to 0.72); certainty not graded.

38% SDF solution (applied biannually) vs 38% SDF solution (applied annually)

Arrest of advanced cavitated carious lesions on any coronal surface · Preschool children with advanced cavitated carious lesions on any coronal surface (primary teeth)

38% SDF solution (applied biannually) was more effective than 38% SDF solution (applied annually) for arrest or reversal of cavitated coronal carious lesions (RR 1.21, 95% CI 1.12 to 1.3; high 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).
