Summary
This study tested different application times (3 seconds to 2 minutes) of 38% silver diamine fluoride solution to see which works best for stopping cavities in preschool children. Over 600 healthy kids aged 3-5 with at least one cavity participated. Researchers checked if the cavity surface became hard (arrested) and looked at tooth color changes. The goal is to find the shortest effective time to make treatment easier for young children.

What this could lead to

What could go wrong
This is a completed Phase 2/3 trial, but the optimal time may still vary by child. SDF can stain teeth black, which may be a cosmetic concern.
