Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests a surgical procedure to cover exposed tooth roots on the tongue side of lower teeth. Twenty adults with gum recession will receive the surgery and be followed for up to 24 months. The main goal is to see how much root coverage is achieved at 6 months, along with other measures like gum thickness and patient comfort.

What this could mean

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

Active substance
Modified Coronally Advanced Tunnel with Connective Tissue Graft (surgical procedure)
What this could lead to
If successful, this surgical technique could offer a reliable way to cover exposed roots on the tongue side of lower teeth, reducing sensitivity and improving gum health.
What could go wrong
This is a very small, early case series with only 20 participants and no comparison group. Results may not apply to everyone, and surgery carries risks like pain, swelling, or graft failure.
