Orthodontic treatment need vs No orthodontic treatment need

Poor oral health-related quality of life (OHRQoL) · Children aged 3-12 years

Orthodontic treatment need was associated with modestly higher odds of poor OHRQoL (OR 1.13, 95% CI 1.07-1.18; 3 studies; ungraded).

Resin-based fissure sealant vs Fluoride varnish

Dentine caries in permanent molars (24 months) · Children and adolescents (general population, aged under 20 years)

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).

440 to 550 ppm F toothpaste vs Non-fluoride (0 ppm F) placebo toothpaste

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

440 to 550 ppm F toothpaste showed no clear difference in caries increment, tooth index D(M)FT compared with non-fluoride (0 ppm F) placebo toothpaste (low certainty).

1000 to 1250 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)

1000 to 1250 ppm F toothpaste may leads to lower caries increment, surface index D(M)FS compared with 250 ppm F toothpaste (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 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).

1000 or 1100 ppm F toothpaste vs Non-fluoride (0 ppm F) placebo toothpaste

Caries increment, tooth index D(M)FT · Adults with mature permanent dentition (aged 18 to 93 years at study start)

1000 or 1100 ppm F toothpaste showed no clear difference in caries increment, tooth index DMFT compared with non-fluoride (0 ppm F) placebo toothpaste (low certainty).

2400 to 2800 ppm F toothpaste vs 1700 to 2200 ppm F toothpaste

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