NCT ID NCT06767670
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how two types of dental crowns—stainless steel and bioflex—affect oral hygiene and bacteria levels in children aged 4 to 8. Each child will get one crown of each type on opposite sides of the mouth. Researchers will measure plaque bacteria and gum health to see which crown leads to a cleaner mouth.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could help dentists choose the best crown type for children's teeth to maintain better oral hygiene and gum health.
- What could go wrong
- This is a small, early-stage study with only 40 children. It measures bacteria and gum health, not long-term tooth survival, so results may not change practice directly.
