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.
