Fluoride varnish vs Fissure sealant (resin-based or glass ionomer)

Caries incidence of occlusal surfaces of first permanent molars · Generally healthy children aged 6 to 9 years with at least one fully erupted first permanent molar with deep fissures or early enamel…

After excluding Bravo 1996, occlusal caries incidence slightly favored fluoride varnish but was not significant, with heterogeneity falling to 0% (RR 0.98, 95% CI 0.82 to 1.16; 3 RCTs; 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 12-15 years (adolescents)

In adolescents (12-15 y) from heavily contaminated areas, individual studies gave inconsistent DMFT/dmft differences; the review did not pool them and drew no firm conclusion (ungraded).

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).

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).

Residence in low-contamination area (approx. 5-15 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 a low-contamination area, individual studies reported higher DMFT/dmft in exposed than non-exposed children; not pooled (ungraded).

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).

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).

Residence in weakly contaminated area (approx. 1-5 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 a weakly contaminated area, one study reported higher DMFT/dmft in exposed than non-exposed children; not pooled (ungraded).

Mineral trioxide aggregate (MTA) pulpotomy dressing vs Platelet-rich fibrin (PRF)

Overall success (composite of clinical and radiographic success) · Immature (young) permanent teeth with open apex and vital pulp exposed to dental caries or trauma, in children aged 6-14 years

A single RCT found no difference in pulpotomy success between MTA and platelet-rich fibrin (both 100% through 24 months; 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

DMFT/DMFS index (dental caries experience) · Children aged 0-12 years in Ireland

The single Irish study showed lower DMFT/S with OHPP (OR 0.52, 95% CI 0.45 to 0.61; ungraded, single study).

Mineral trioxide aggregate (MTA) pulpotomy dressing vs Calcium hydroxide (CH)

Overall success (composite of clinical and radiographic success) · Immature (young) permanent teeth with open apex and vital pulp exposed to dental caries or trauma, in children aged 6-14 years

MTA and calcium hydroxide had similar clinical and radiographic pulpotomy success at 6 months (RR 1.00, 95% CI 0.94 to 1.06; 2 RCTs; ungraded).

Learning disability (CLD) vs No learning disability (CNLD)

Care index (CI), permanent teeth · Children aged 1-18 years

The care index (met dental care need) for permanent teeth could not be meta-analyzed because no study reported variance; it was lower or equal in children with learning disabilities in 5 of 8 studies (certainty not graded).

DMFT/DMFS index (dental caries experience) · Children aged 0-12 years in Japan

The single Japanese study yielded a degenerate estimate of OR 0.00 (95% CI 0.00 to 0.00; ungraded, single study).

Mineral trioxide aggregate (MTA) pulpotomy dressing vs Calcium-enriched mixture (CEM)

Overall success (composite of clinical and radiographic success) · Immature (young) permanent teeth with open apex and vital pulp exposed to dental caries or trauma, in children aged 6-14 years

A single RCT found no difference in pulpotomy success between MTA and calcium-enriched mixture (both 100% at 6 and 12 months; not pooled; ungraded).

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).

Learning disability (CLD) vs No learning disability (CNLD)

Restorative index (RI), permanent teeth · Children aged 1-18 years

The restorative index for permanent teeth could not be meta-analyzed (no variance data); it was lower or equal in children with learning disabilities in 4 of 9 studies, and the pattern suggested more extraction- than restoration-based care in CLD (certainty not graded).
