“A single dose of either topical treatment given in elementary schools prevented roughly 80% of cavities and kept 50% of cavities from worsening when children were seen two years later.”
NYU’s trial covered 2,998 kids at 47 New York City schools, most from low-income families. Silver diamine fluoride brushed on once worked as well as sealants, 81% against 82%, and it is quicker to apply. Low-income kids get twice the cavities, and a dentist visit means a parent losing time at work. The fix was one coat of liquid at school.
