Association between early childhood caries and anthropometric growth and nutritional status in preschool children: a cross-sectional study

In this population, ECC was common. Modifiable behaviors and parental knowledge were strongly associated with ECC, and greater caries severity was linked to lower WHZ, suggesting a relationship between ECC and acute nutritional status. Strengthening sugar intake control, bedtime toothbrushing, fluoride use, and routine dental examinations may help prevent ECC and mitigate its potential impact on growth.
