Early childhood caries (ECC) - incidence/risk · Children with exclusively primary dentition (age ≤71 months)
Breastfeeding beyond 24 months is associated with an increased risk (incidence) of early childhood caries versus not breastfeeding at the same age (RR 2.44, 95% CI 1.97 to 3.02; low certainty).

Early childhood caries experience (mean dmft) · Nigerian children with primary dentition (approximately 6 months to 5 years)
In primary dentition, high-frequency sugar consumption was associated with slightly higher, non-significant odds of caries (OR 1.13, 95% CI 0.23 to 5.44), with high heterogeneity (I2=83%; ungraded).

Dental caries in permanent teeth · Nigerian individuals with permanent dentition (approximately 12 years and older)
In permanent dentition, high-frequency sugar consumption was associated with non-significant 15% higher odds of caries (OR 1.15, 95% CI 0.88 to 1.52), with no heterogeneity (I2=0%; ungraded).
1 finding from 1 review
Dental caries prevalence · Nigerian individuals, including children and adults, with primary or permanent dentition
High-frequency sugar consumption was associated with 18% higher but non-significant odds of dental caries in Nigeria (OR 1.18, 95% CI 0.87 to 1.59; I2=36%; ungraded).

Plaque index (PI) / oral hygiene · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
School-based interventions may reduce dental plaque scores (SMD -0.32, favouring intervention), but the certainty of evidence is very low.

Oral hygiene measured by mean gingival scores · Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
The effect of school-based interventions on gingival scores is uncertain and not statistically significant (SMD 0.12; very low certainty).
