What concentration of neutral sodium fluoride is considered a professionally applied fluoride agent?

The concentration of neutral sodium fluoride that is recognized as a professionally applied fluoride agent is 2.0%. This concentration is typically used in clinical settings for topical fluoride applications and is effective in enhancing the remineralization of enamel, providing protection against dental caries.

Neutral sodium fluoride at this concentration is favored because it is less likely to cause irritation or sensitivity in patients compared to higher concentrations, while still being strong enough to offer protective benefits. It can be used in various forms, such as gels or foams, and is applied in dental offices as a preventive treatment to help maintain oral health.

The aforementioned concentration balances efficacy with safety, making it suitable for a wide range of patients, including children and those who may be more susceptible to fluoride exposure.
