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

Background: Enamel hypoplasia (EH) increases risk for dental caries and also is associated with vitamin D deficiencies. This pilot study evaluates the feasibility to determine the association of human maternal circulating vitamin D concentrations during pregnancy and EH in infant's teeth that develop in utero.

Methods: A pilot population of 37 children whose mothers participated in a RCT of vitamin D supplementation during pregnancy was evaluated.
