Hypothesis
What is the appropriate amount of fluoride to use in professional topical applications and how much fluoride remains in the oral cavity afterwards?
Conclusion
The study found that approximately 0.8 g of NaF foam is the appropriate amount to use, with about 25% of the fluoride remaining in the oral cavity after application.
Supporting Evidence
- The appropriate amount of NaF foam was found to be approximately 0.8 g.
- The residual fluoride in the oral cavity was approximately 25% of the amount of foam used.
- The mean fluoride concentration in saliva peaked at 35.95 ppm five minutes after application.
Takeaway
When dentists use fluoride foam to help prevent cavities, they should use about a small amount, like a spoonful, and most of it stays in your mouth after they apply it.
Methodology
The study involved applying 2% neutral sodium fluoride foam to eight adult subjects and measuring the fluoride concentration in saliva and the residual fluoride in the oral cavity.
Limitations
The sample size was small, which may have affected the variability in results.
Participant Demographics
Eight healthy participants aged 21.3 to 24.8 years, including three males and five females.
