Unfavourable oral hygiene and dietary habits (frequent sweet/sugar consumption; low toothbrushing frequency in early childhood) vs Favourable oral hygiene and dietary habits

Caries development in permanent teeth · School children and adolescents (6-18 years) followed from primary dentition (baseline examination before 72 months of age)

Early-childhood oral hygiene and dietary habits show inconsistent associations with permanent-teeth caries, often losing significance after adjustment for past caries (2 studies; not pooled; not GRADE-rated).

Low tooth brushing frequency (<2 times/day) vs High tooth brushing frequency (>=2 times/day)

Early childhood caries (ECC) · Healthy children under 6 years of age (6 months to 6 years); preschool children

After excluding an extreme outlier (Alhabdan 2018), the association between low brushing frequency and ECC remained statistically significant (pooled OR approximately 2.0, p=0.003; I2=87.5%); the exact estimate and its CI were not reported; ungraded.
