Dental changes in hypervitaminosis D.

Vitamin D is required for the normal development of teeth and bones. When there is excess vitamin D, systemic and dental changes may occur. This is a case report of a girl who experienced hypercalcemia secondary to excess vitamin D derived from the consumption of milk that was incorrectly fortified. The changes in the permanent dentition to date are enamel hypoplasia and focal pulp calcification. These changes correspond to the timing of the toxemia caused by hypervitaminosis D.
