Question

Which of the following is considered a caries-promoting mineral?

• A. Selenium
• B. Vanadium
• C. Lead
• D. Molybdenum

Hint:

Remember: Fluoride, molybdenum, and vanadium are caries-inhibiting, whereas selenium is caries-promoting.

Answer 1

The Correct Option is A

Step 1: Understanding Caries-Promoting Minerals.
Dental caries results from demineralization of tooth enamel due to acid production by bacteria.
Certain trace elements influence susceptibility to dental caries.
Some minerals are caries-inhibiting, while others promote caries formation.
Step 2: Role of Selenium.
Selenium has been observed to increase susceptibility to dental caries.
It may interfere with enamel mineralization and reduce resistance to acid attack.
Thus, it is considered a caries-promoting mineral.
Step 3: Analysis of Other Options.
Vanadium is known to have caries-inhibiting properties.
Molybdenum is also associated with reduced caries prevalence.
Lead does not have a well-established direct caries-promoting role like selenium.
Step 4: Conclusion.
Therefore, among the given options, Selenium is considered a caries-promoting mineral.
