RESUMEN
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.

An unusual defect was noted in a 10-year-old girl near the usual site of administration for an inferior nerve block. It was interpreted to be the result of a local anesthetic having been administered 2 months previously.
