Summary

This study looks at children aged 10-15 who need braces for prominent upper front teeth. Some will have upper premolars removed as part of treatment, others will not. Researchers will use sleep studies before and after treatment to see if the extractions increase the risk of obstructive sleep apnea. The goal is to help orthodontists make safer treatment decisions.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
upper premolar extraction
What this could lead to
If this study succeeds, it could help orthodontists understand whether removing upper premolars affects a child's risk of sleep apnea, leading to safer treatment choices.
What could go wrong
This trial is small (60 participants) and currently suspended, so results may not be reliable or generalizable. It only measures risk, not a treatment benefit.
