Battle of the smile fixers: which treatment brightens Fluorosis-Stained teeth best?
NCT ID NCT07707349
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This trial compares two minimally invasive treatments—Antivet and Opalustre—for improving the appearance of mild enamel fluorosis, a condition that causes tooth discoloration. Adults aged 20 to 35 with mild fluorosis on their front teeth are randomly assigned to receive one of the two treatments. Tooth color is measured before and after treatment using a special device to see which option works better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Antivet (microabrasion) or Opalustre (enamel microabrasion)
- What this could lead to
- If one treatment proves more effective, it could offer a better option for improving the appearance of discolored teeth due to fluorosis.
- What could go wrong
- This is a small trial with only 59 participants, and results may not apply to everyone. Both treatments are minimally invasive, but individual results vary.
