Question

centers for disease control and prevention
the discolored teeth in the image above are most likely a result of
multiple choice
deficient calcium intake
excessive fluoride intake
insufficient fluoride intake
excessive calcium intake

Explanation:

To determine the cause of discolored teeth, we analyze each option:

• Deficient calcium intake (first option) typically affects bone health and tooth development in more severe deficiency, not usually causing discoloration as a primary sign.
• Excessive fluoride intake (second option) can lead to dental fluorosis, which causes tooth discoloration (mottling) and enamel defects.
• Insufficient fluoride intake (third option) leads to increased dental caries risk, not discoloration.
• Excessive calcium intake (fourth option) does not cause tooth discoloration as a primary effect.

So the most likely cause is excessive fluoride intake.

Answer:

B. excessive fluoride intake
