Scheduled dental recall intervals (1-, 3- or 6-monthly; oral hygiene instruction with or without scale and polish) plus daily supervised toothbrushing by carers vs usual care

Plaque · Adults (mean age 30.9 years), level of ID unclear; setting day centre

Scheduled dental recall intervals (1-, 3- or 6-monthly; oral hygiene… may leads to lower plaque (long term) compared with usual care (no specific treatment) (low certainty).

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).

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 higher pulpotomy success with triple antibiotic paste than abscess remedy (100% vs 80%; statistically significant, P<0.05; not pooled; ungraded).

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

Early childhood caries experience (mean dmft) · Children aged 1-18 years

In primary teeth, meta-analysis found no evidence of a difference in caries experience (dmft/deft) between children with and without learning disabilities (SMD 0.41, 95% CI -0.14 to 0.96; 8 studies; certainty not graded).

Caries increment, surface index D(M)FS · Young children with primary (deciduous) dentition (aged 1 to 6 years at study start)

1500 ppm F toothpaste probably leads to lower caries increment, surface index d(m)fs compared with non-fluoride (0 ppm F) placebo toothpaste (moderate certainty).

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 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).

Silver diamine fluoride (SDF; 30% or 38%) vs Fluoride varnish

Arrest of dentine caries · Preschool children with active dentine caries in primary teeth (mean age 3.4-4.0 years)

Silver diamine fluoride was about 2.5 times more likely than sodium fluoride to arrest dentine caries surfaces at 18 months (pooled OR 2.51, 95% CI 1.25 to 5.10; 2 RCTs), although between-study heterogeneity was high (I2=90.3%); certainty of evidence was not formally graded.

2400 to 2800 ppm F toothpaste vs 250 ppm F toothpaste

Caries increment, surface index D(M)FS · Children and adolescents with immature permanent dentition (aged 5 to 16 years at study start)

2400 to 2800 ppm F toothpaste may leads to lower caries increment, surface index D(M)FS compared with 250 ppm F toothpaste (low certainty).

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 (studies published 2015 or later)

In studies published from 2015 onward, OHPPs were associated with lower DMFT (OR 0.08, 95% CI 0.01 to 0.53; ungraded).
