Which fluoride treatment is known for a higher risk of fluoride ingestion?

The option indicating a higher risk of fluoride ingestion is associated with the dual rinse of acidulated phosphate fluoride and stannous fluoride. This combination involves using two fluoride agents simultaneously, which may increase the total fluoride exposure and the likelihood of ingestion during treatment.

The use of acidulated phosphate fluoride alone is generally applied in a controlled manner, with guidelines in place to minimize excessive intake. Similarly, stannous fluoride is usually applied in moderation. However, when both types are combined in a rinse, it can lead to an increased volume of fluoride being present in the mouth at one time, and if patients swallow any of the solution during the process, it raises the risk of ingestion compared to using either of the treatments alone.

Safety protocols emphasize the importance of minimizing fluoride ingestion, particularly in vulnerable populations such as children, making awareness of dual rinse practices crucial for dental professionals. This context underlines why the combination treatment carries a heightened risk.
