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 Results may not be published yet.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

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

The goal of this clinical trial was to compare three ways of helping the jawbone heal after removal of a tooth. The jawbone that supports a tooth is called the alveolar ridge. This bone can become narrower after a tooth is removed. Participants were randomly assigned to one of three groups. One group received no bone graft material. One group received mineralized dentin graft made from the participant's extracted tooth. One group received beta-tricalcium phosphate, which is a synthetic bone graft material. Participants had cone-beam computed tomography, a three-dimensional dental X-ray, immediately after tooth removal and again after 6 months. During dental implant placement at 6 months, researchers collected a small bone sample to examine healing.
