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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This small study tested two methods for cleaning infected root canals: ultrasonic activation and a 980-nm diode laser. Sixteen adults with dead (necrotic) teeth had their root canals cleaned with one of these methods. Researchers checked for leftover bacterial DNA to see which method worked better. The goal is to find the most effective way to reduce bacteria during root canal treatment.

What this could mean

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

Active substance
3% sodium hypochlorite irrigation activated by ultrasonic or diode laser
What this could lead to
If one method proves better at removing bacteria, it could improve root canal success rates.
What could go wrong
This is a very small pilot study with only 16 participants, so results may not apply to all cases. It measures bacterial DNA, not actual infection outcomes.

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
