Which option describes a high-dose fluoride topical treatment delivered 1-2 times per year under dentist's control?

• A. Fluoride varnish
• B. Professionally applied fluoride gels
• C. Fluoride toothpaste
• D. Fluoride rinse

Answer: (B)

The concept being tested is an in-office, high-concentration fluoride treatment given under the dentist’s supervision. Professionally applied fluoride gels are used in the clinic with a tray that holds the gel against the teeth for a set duration, allowing the clinician to control both the dose and the contact time. This setup delivers a higher fluoride exposure than what is available in over-the-counter toothpaste or rinses, yet remains a manageable regimen when scheduled at 1- to 2-yearly intervals for patients at risk. The clinician can tailor the treatment to the individual, ensure proper application, and minimize ingestion, which fits the idea of a high-dose topical therapy delivered under professional control. Fluoride varnish is also a high-dose option used in the office, but its typical protocol often involves more frequent applications based on risk, whereas the gels described here align with the 1-2 times per year framework. Fluoride toothpaste and fluoride rinse are home-use products with much lower fluoride exposure per use, not forming the described in-office, high-dose, clinician-controlled approach.
