Resin-based fissure sealant vs Fluoride varnish

DMFS (decayed, missing, filled surfaces) increment, occlusal surfaces · Schoolchildren aged 6-12 years with sound occlusal surfaces of the first permanent molars

Pit and fissure sealant and fluoride varnish showed no statistically significant difference in DMFS increment at 24 months (SMD -0.13, 95% CI -0.67 to 0.40; I2=92%; not GRADE-rated).

Fluoride supplementation (tablets, drops, lozenges or chewing gum) vs placebo or no treatment

Decayed primary surfaces at 3 years · Pregnant women (for preventing dental caries in the primary teeth of their children)

Fluoride supplementation (tablets, drops, lozenges or chewing gum) showed no clear difference in decayed primary surfaces at 3 years compared with placebo or no treatment; GRADE not reported.

Women who experienced preterm birth vs Women who did not experience preterm birth (term)

Decayed, missing, filled surfaces (DMFS) · pregnant women

Women who experienced preterm birth did not have a significantly different DMFS than those who did not (mean difference -0.15, 95% CI -3.40 to 3.09; 3 studies; I2=89%); certainty of evidence not graded.

Fluoride supplementation (tablets, drops, lozenges or chewing gum) vs placebo or no treatment

Decayed or filled primary tooth surfaces at 3 years · Pregnant women (for preventing dental caries in the primary teeth of their children)

It is very uncertain whether fluoride supplementation (tablets, drops, lozenges or chewing gum) changes decayed or filled primary tooth surfaces at 3 years compared with placebo or no treatment (very low certainty).

Fluoride supplementation (tablets, drops, lozenges or chewing gum) vs placebo or no treatment

Decayed or filled primary tooth surfaces at 5 years · Pregnant women (for preventing dental caries in the primary teeth of their children)

It is very uncertain whether fluoride supplementation (tablets, drops, lozenges or chewing gum) changes decayed or filled primary tooth surfaces at 5 years compared with placebo or no treatment (very low certainty).

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

Increment of occlusal DMFS (decayed, missing, filled surfaces) of FPMs · Generally healthy children aged 6 to 9 years with at least one fully erupted first permanent molar with deep fissures or early enamel…

Fluoride varnish and fissure sealant did not differ significantly in occlusal DMFS increment of FPMs (MD 0.13, 95% CI -0.09 to 0.34; 3 RCTs; ungraded).

Advice about a healthy diet (including breastfeeding promotion and sugar avoidance) and feeding practices (e.g. relating to bottle-feeding and sleep) for infants and young children vs usual care

dmfs index score (decayed, missing, filled primary surfaces; range 0-80) · For interventions, pregnant women, mothers or other caregivers of infants in the first year of life; for outcomes, children up to 6 years…

Advice about a healthy diet (including breastfeeding promotion and… showed no clear difference in dmfs index score (decayed, missing, filled primary surfaces; range… compared with standard care (low certainty).

Resin-based fissure sealant vs Fluoride varnish

Change in DMFS (decayed, missing and filled permanent surfaces) increment · Children and adolescents (general population, aged under 20 years)

Resin-based fissure sealant led to lower change in DMFS (decayed, missing and filled permanent surfaces)… compared with fluoride varnish; GRADE not reported.

Vegetarian diet (any diet excluding all meat, poultry and fish) vs Nonvegetarian diet

Dental caries measures other than pooled DMFT (DMFS, decayed/filled surfaces and teeth, root caries, nonvisible lesions, white spots) · General population (children and adults) assessed for dental hard-tissue health

Evidence on other dental-caries measures was inconsistent: some indices (decayed surfaces/teeth, root caries, white spots) were higher in vegetarians while some studies found lower caries in vegetarian children (ungraded).
