NBDHE Using Preventative Agents Practice Test

Sodium fluoride is the correct choice because it is widely recognized for its role in both community water fluoridation programs and professionally applied fluoride treatments. It is effective in reducing dental caries by enhancing the remineralization of enamel and inhibiting the metabolism of bacteria in dental plaque.

In water fluoridation, sodium fluoride is chosen for its solubility and ability to provide fluoride ions that can be readily assimilated by the community. Additionally, its use in professional applications includes topical treatments where it provides a protective effect against enamel demineralization and caries. The stability and safety profile of sodium fluoride make it a preferred agent for these purposes.

Other fluoride agents mentioned have specific uses that do not align with water fluoridation practices. Acidulated phosphate fluoride (APF) is typically used in professional applications but is not used in water fluoridation due to its acidic nature, which may not be suitable for long-term exposure in drinking water. Stannous fluoride is known for its antibacterial properties and is often used in toothpaste, but its applications are more limited compared to sodium fluoride. Sodium monofluorophosphate (MFP) is primarily used in dentifrices and has a different mechanism of action that is more geared towards remineral
