Question

After removing deposits from the client's teeth, you have planned to use a fluoride gel on the teeth because you ran out of fluoride varnish. What is the maximum amount of fluoride that should be placed in the tray?

1) 1.23%
2) 2.45%
3) 3.67%
4) 4.89%

Answer 1

The maximum amount of fluoride that should be placed in the tray is 2.45%. Fluoride is commonly used in dental treatments to prevent tooth decay, and a concentration of 2.45% in the fluoride gel would provide an effective preventive effect without increasing the risk of harm.

Step-by-step explanation:

The maximum amount of fluoride that should be placed in the tray is 2.45%.

Fluoride is commonly used in dental treatments to prevent tooth decay. The fluoride content in toothpaste typically ranges from 1,000 to 1,100 parts per million (ppm) or 0.1% to 0.11%. European countries often have higher fluoride content, with a common NaF content of 0.312% w/w (1,450 ppm fluoride). These concentrations are likely to prevent tooth decay.

Based on this information, a concentration of 2.45% in the fluoride gel would provide an effective preventive effect without increasing the risk of harm associated with higher concentrations of fluoride.
