What is the maximum amount of gel that should be placed in a fluoride tray for application?

4ml
8ml
2ml
12ml

The correct answer is: 4ml

The correct answer is based on the recommended guidelines for fluoride treatments. For fluoride tray application, the maximum amount of fluoride gel that should be dispensed into each tray is typically 4 milliliters. This amount is considered optimal to ensure adequate coverage of the teeth while minimizing the risk of swallowing excess gel. Using more than this amount can lead to waste and may increase the likelihood of fluoride ingestion, which could have adverse effects and lead to systemic toxicity, especially in children. Therefore, adhering to the 4 ml guideline helps maintain a safe and effective treatment process. The other options exceed the safe and effective amount that is commonly recommended in dental practice, thus they would not be advisable for use in this context.
