In school water fluoridation programme, the level of fluoride as compared to the level in community water fluoridation is:
**Core Concept**
The school water fluoridation programme aims to prevent tooth decay by providing fluoride to children during school hours. **Fluoride** levels are crucial in determining the effectiveness of this programme.
**Why the Correct Answer is Right**
The correct answer is not provided, however, in general, the level of fluoride in school water fluoridation programmes is typically higher than in community water fluoridation. This is because children spend only a portion of their day at school, so a higher concentration of **fluoride** is needed to achieve the desired preventive effect.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the level of fluoride in school water fluoridation is not typically lower than in community water fluoridation.
**Option B:** This option is incorrect because the level of fluoride is not the same in both programmes.
**Option C:** This option is incorrect because it is not the correct comparison.
**Clinical Pearl / High-Yield Fact**
The optimal level of **fluoride** in community water fluoridation is around 1 part per million. School water fluoridation programmes often use higher concentrations to compensate for less exposure time.
**Correct Answer:** D. Higher
