Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This study compares two surgical techniques—coronally advanced flap (CAF) and tunneled coronally advanced flap (TCAF)—both combined with a soft tissue graft, to treat receding gums in the upper jaw. Thirty-four adults with multiple gum recessions will be randomly assigned to one procedure and followed for up to 10 years. The goal is to see which method provides better root coverage, which can reduce tooth sensitivity and improve appearance.

What this could mean

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

Active substance
surgical procedure (coronally advanced flap or tunneled coronally advanced flap with connective tissue graft)
What this could lead to
If one technique proves better, it could lead to more effective and lasting gum recession coverage, reducing tooth sensitivity and improving smile aesthetics.
What could go wrong
This is a small, early-stage trial with only 34 participants. Results may not apply to everyone, and surgery carries risks like pain, swelling, or graft failure.
