Socioeconomic status category vs Not applicable (single-group prevalence)

Low SES prevalence (among children with caries) · Children with dental caries (deciduous and/or permanent dentition) in low- and middle-income countries

About 36% of children with caries in LMICs were of low SES (pooled prevalence 0.359, 95% CI 0.167 to 0.578; 4 studies; not GRADE-rated).

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

Caries presence in primary teeth · 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 children with caries in the primary teeth at 3 years compared with placebo or no treatment (very low certainty).
