According to the rule of 6s with fluoride, a patient does NOT need systemic fluoride if the fluoride level in drinking water is more than how many ppm?

0.6ppm
1.0ppm
0.3ppm
2.0ppm

The correct answer is: 0.6ppm

The rule of 6s with fluoride states that a patient does not need systemic fluoride if the fluoride level in drinking water is at least 0.6ppm. This means that if the fluoride level is at least 0.6ppm, the patient is already receiving a sufficient amount of fluoride through their drinking water and does not need additional fluoride treatments. Therefore, options B, C, and D are incorrect because they are not within the 0.6ppm or higher range specified by the rule of 6s. Option B is too high, while options C and D are too low. It is important to note that the rule of 6s applies specifically to systemic fluoride and does not apply to topical fluoride treatments.
