What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting This study
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
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 Results may not be published yet.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.
Cancelled
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

Researchers at the University of Nebraska are studying how older adults heal after having a back tooth removed. Participants will provide saliva, gum fluid, and blood samples before the extraction, then return for checkups at 1 week, 2 weeks, and 3 months to track healing and bone changes. The goal is to understand the biological markers of wound healing in older people, which could help improve dental care for this age group.

What this could mean

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

Active substance
tooth extraction
What this could lead to
If successful, this could reveal how aging affects oral wound healing and point toward ways to improve recovery after dental procedures in older adults.
What could go wrong
This is a small observational study, so results may not apply broadly. It measures healing markers, not long-term outcomes, and cannot prove cause and effect.

This is an AI summary of the original study and may miss details. Read our disclaimer.
