NCT ID NCT05403125
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This early-phase trial tested whether a special fluoride treatment (silver diamine fluoride) can prevent tooth decay in 56 head and neck cancer patients undergoing radiation therapy. Patients received a one-time professional application of the silver solution plus a fluoride gel for home use. The study aimed to see if this simple addition to dental care could reduce cavities and improve quality of life.
