For a 5-year-old child in a non-fluoridated area with a fluoride level of 0.2 ppm, what is the recommended daily dosage of sodium fluoride?

For a 5-year-old child residing in a non-fluoridated area where the fluoride level is 0.2 ppm, the recommended daily dosage of sodium fluoride aligns with the established guidelines for fluoride supplementation.

In areas with low fluoride levels in the drinking water, such as 0.2 ppm, children's teeth are at a greater risk for dental caries. Thus, it is important to ensure they receive adequate fluoride to help prevent cavities. The American Dental Association (ADA) recommends a specific additional fluoride dosage based on the fluoride concentration of the water supply.

In this scenario, the guideline suggests that for children aged 6 months to 16 years who live in non-fluoridated areas, if the water supply has a fluoride concentration of less than 0.3 ppm, the recommended daily dosage for a child aged 5 years is typically around 0.50 mg of sodium fluoride. This dosage accounts for their developmental stage and the need to balance fluoride intake for optimum dental health while minimizing the risk of dental fluorosis.

Thus, the correct daily dosage for this 5-year-old child is indeed 0.50 mg NaF, which effectively addresses the child's needs in a non-fluoridated environment while
