Relationship between Maternal Prenatal Vitamin D Status and Early Childhood Caries in Their Children: A Cross-sectional Survey.

Background: Vitamin D deficiency in expectant mothers is very common in India. As a consequence, the possibility of hypoplasia of teeth and resultant propensity for faster progression of early childhood caries (ECC) is expected to be higher in Indian children.

Aim: This study aimed to determine the relationship between prenatal vitamin D intake of mothers and dental caries experience in their preschool children, and whether vitamin D deficiency in mothers could be a risk factor for tooth decay in their children.
