How does enamel fluorosis develop?

How does enamel fluorosis develop?

• A. High fluoride levels disrupt enamel maturation and increase enamel porosity.
• B. Fluorosis develops from fluoride deficiency during enamel formation.
• C. Fluorosis results from excessive calcium intake.
• D. Fluorosis is caused by lack of fluoride in drinking water.

Answer: (A)

Excess fluoride exposure during the time permanent teeth are forming leads to fluorosis. During enamel formation, the enamel matrix is laid down and then mineralized in a controlled maturation phase. When fluoride levels are too high, this maturation process is disrupted, causing hypomineralization and increased porosity of the enamel. The result is enamel that is porous and mottled in appearance. Fluorosis arises from overexposure in early childhood, not from fluoride deficiency or lack of fluoride in water, and it isn’t caused by excess calcium.
