Question

The Galagan and Vermillion formula for determining optimal fluoride concentration in drinking water takes into account body weight and which of the following factors?

• A. Age
• B. Height
• C. Climatic conditions
• D. Gender

Hint:

Optimal fluoride concentration is temperature-dependent because water intake increases in hotter climates.

Answer 1

The Correct Option is C

Step 1: Understanding the Principle of the Formula.
The Galagan and Vermillion formula is designed to determine the optimal fluoride concentration in community water suppliesIt is based on the idea that fluoride intake depends on the amount of water consumed by an individual
Step 2: Effect of Climate on Water Consumption.
Water consumption varies according to environmental temperatureIn hot climates, individuals drink more water due to increased perspiration and fluid lossIn cold climates, water intake is comparatively lowerThus, climatic conditions directly influence the total fluoride intake
Step 3: Evaluation of the Options.
(A) Age: Although fluoride requirement varies with age, the formula does not primarily depend on age as a determining factor
(B) Height: Height does not significantly influence water consumption in this context
(C) Climatic conditions: CorrectThe formula specifically adjusts fluoride concentration based on temperature and climate
(D) Gender: Gender is not included as a variable in this formula
Step 4: Conclusion.
Therefore, along with body weight, the Galagan and Vermillion formula takes into account climatic conditions when determining the optimal fluoride concentration
