Excess vitamin D intake can cause hypercalcemia and dental issues. This case report highlights enamel hypoplasia and pulp calcification in a child due to incorrectly fortified milk.

Area of Science:

Biochemistry
Pediatric Dentistry
Endocrinology

Background:

Vitamin D is essential for skeletal and dental health.
Hypervitaminosis D can lead to systemic toxicity, including hypercalcemia.
Dental development is sensitive to metabolic disturbances.

Observation:

A case of a young girl with hypercalcemia is presented.
The hypercalcemia was linked to excessive vitamin D intake from erroneously fortified milk.
Dental examination revealed enamel hypoplasia and focal pulp calcification in permanent teeth.

Findings:

The observed dental anomalies, enamel hypoplasia and focal pulp calcification, occurred during the period of vitamin D toxicity.
These findings correlate with the timing of hypercalcemia and hypervitaminosis D.

The case demonstrates a direct link between excessive vitamin D and dental developmental defects.

Implications:

This case underscores the critical importance of accurate milk fortification to prevent vitamin D toxicity.
It highlights the potential for significant dental changes secondary to iatrogenic hypervitaminosis D.
Dentists and pediatricians should consider vitamin D toxicity in cases of unexplained enamel defects and hypercalcemia.
