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 5-7 years (early school-age)

In early school-age children (5-7 y) from weakly contaminated areas, individual cross-sectional studies reported mostly higher but inconsistent DMFT/dmft in exposed vs non-exposed children; the review did not pool the data and drew no firm conclusion (ungraded).

Residence in heavily contaminated area (approx. 15-40 Ci/km2) vs Residence in non-contaminated (non-exposed) area (<1 Ci/km2)

Dental caries · Children of mixed ages (mean approximately 12 years; no age separation)

In children of mixed ages from heavily contaminated areas, individual studies reported modestly higher DMFT/dmft in exposed children; the review did not pool them and drew no firm conclusion (ungraded).

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).

Residence in heavily contaminated area (approx. 15-40 Ci/km2) vs Residence in non-contaminated (non-exposed) area (<1 Ci/km2)

Dental caries · Children aged 5-7 years (early school-age)

In early school-age children (5-7 y) from heavily contaminated areas, individual studies gave conflicting DMFT/dmft differences (some favouring exposed, some non-exposed); the review did not pool them (ungraded).

Dental caries · Children aged 5-7 years (early school-age)

In early school-age children (5-7 y) from a low-contamination area, one study reported higher DMFT/dmft in exposed than non-exposed children; the estimate was not pooled (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

Incremental cost‐effectiveness · Children younger than 6 years (healthy except for dental caries)

In children younger than 6 years, OHPPs were associated with lower cost per DMFT/S (OR 0.07, 95% CI 0.02 to 0.32; ungraded).
