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
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 This study
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 Results may not be published yet.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

This study looked at 66 postmenopausal women with osteoporosis who were either taking alendronate (a common bone-strengthening drug) or not. Researchers measured how well the jawbone healed after a tooth extraction using X-rays taken right after, then at 30 and 90 days. The goal was to see if alendronate might be a risk factor for slower bone healing in the jaw.

What this could mean

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

Active substance
alendronate
What this could lead to
If successful, this could help dentists and doctors better manage tooth extractions in women taking alendronate for osteoporosis.
What could go wrong
This is a small, completed observational study, not a treatment trial. It only looks at bone healing after extraction, so it won't change how osteoporosis is treated.
