Institutionalization (living in an orphanage/institution) vs Parented children living with their families

Dental caries prevalence · Institutionalized orphan children (roughly 3 to 18 years)

Institutionalized orphan children may be at higher risk of dental caries than parented children (pooled RR 1.19), but the estimate is imprecise and not statistically significant (very low certainty).

Prenatal vitamin D deficiency (low maternal 25(OH)D during pregnancy) vs Adequate prenatal vitamin D (sufficient maternal 25(OH)D)

Dental caries prevalence · Children aged 2 to 8 years

The review reported 44% dental caries prevalence among children of mothers with low prenatal vitamin D.

Intervention not reported

Dental caries prevalence in primary teeth (cavitated lesions) · Children aged 5-6 years in Latin America and the Caribbean

In other Latin American/Caribbean countries, pooled primary-teeth caries prevalence was 70% (95% CI 59-79%), significantly higher than Brazil (p=0.002); certainty not graded.

Intervention not reported

Dental caries prevalence in primary teeth (cavitated lesions) · Children aged 5-6 years in Latin America and the Caribbean

About 56% of 5-6 year-old children in Latin America and the Caribbean had dental caries in primary teeth (95% CI 52-59%); certainty not graded.

Dental caries prevalence in permanent teeth (cavitated lesions) · Children aged 11-13 years in Latin America and the Caribbean

In other Latin American/Caribbean countries, pooled permanent-teeth caries prevalence was 64% (95% CI 45-79%), not significantly different from Brazil (p=0.42); certainty not graded.

Intervention not reported

Dental caries prevalence in permanent teeth (cavitated lesions) · Children aged 11-13 years in Latin America and the Caribbean

In Brazil, pooled permanent-teeth caries prevalence in 11-13 year-olds was 56% (95% CI 53-60%), with a significant declining trend over time; certainty not graded.

Intervention not reported

Dental caries prevalence in permanent teeth (cavitated lesions) · Children aged 11-13 years in Latin America and the Caribbean

About 58% of 11-13 year-old children in Latin America and the Caribbean had dental caries in permanent teeth (95% CI 54-61%); certainty not graded.

Primary school-based interventions (one or more of: school health policy, oral health education, healthy school environment, access to oral health services, community involvement) vs usual practice

Dental caries prevalence measured by dmft or DMFT/S score greater than one · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)

School-based interventions may reduce the prevalence of dental caries (RR 0.70, favouring intervention), but the certainty of evidence is very low.
