Prenatal vitamin D and enamel hypoplasia in human primary maxillary central incisors: A pilot study

Preliminary results suggest follow-up of children of mothers in a vitamin D supplementation RCT during pregnancy provides an important approach to study the etiology of EH in the primary teeth. Further study is needed to discern thresholds and timing of maternal serum 25(OH)D concentrations during pregnancy associated with absence of EH in teeth that develop in utero. Potential dental public health implications for prevention of early childhood caries via sound tooth structure as related to maternal vitamin D sufficiency during pregnancy need to be determined.
