The journal Pediatrics reported a study from the University of Manitoba that followed 133 mothers and their 135 infants in the first year of life. The researchers measured the mothers' serum vitamin D levels during pregnancy and compared them with dental decay rates in their infants. Of the women, 33 had deficient vitamin D levels. Their infants had a 22% rate of enamel hypoplasia and a 23% rate of early childhood dental decay. Mothers of children with early childhood decay had significantly lower prenatal vitamin D concentrations. The researchers theorized that prenatal vitamin D levels may have an influence on the development of healthy primary teeth in their infants.
