Prenatal vitamin D level ≤50 nmol/L vs Adequate prenatal vitamin D (sufficient maternal 25(OH)D)

Dental caries · Children aged 2 to 8 years

The review reported a lower odds ratio at maternal prenatal vitamin D ≤50 nmol/L than at ≤35 nmol/L, without a numeric value in the available sources.

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.

38% SDF one-time application without brushing programme vs no treatment without brushing programme

new carious lesions or fillings · Children with dental caries in permanent (first) molars

The review reported no significant result for SDF; no effect estimate or GRADE rating was reported.

Co-presence of Veillonella spp. with Streptococcus mutans vs Streptococcus mutans acidogenesis without Veillonella spp. modulation (conceptual)

Streptococcus mutans acid (lactic acid) production and cariogenic potential · Oral biofilm of children/individuals at risk of dental caries

The review concludes that Veillonella spp. may modulate (often inhibit) S. mutans acid production and compete for lactate substrate, potentially reducing cariogenesis, but the evidence is narrative and ungraded.

Silver diamine fluoride (SDF) vs Other methods (pooled: ART/glass ionomer cement, nano-silver fluoride, placebo)

Caries arrestment at the individual (patient) level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

Compared with other caries-management methods, SDF may increase caries arrestment at the individual level, but the pooled estimate is very imprecise (low certainty).

Silver diamine fluoride (SDF) vs Atraumatic restorative treatment (ART) with glass ionomer cement (GIC) or glass ionomer material

Caries arrestment at the individual (patient) level · Children and adults with active dental caries (aged 1-50; mostly preschool/school children with primary dentition)

In one trial, SDF greatly increased individual-level caries arrestment versus ART/glass ionomer cement (OR 18.03); this subgroup was not separately GRADE-rated.
