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 Results may not be published yet.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.

Summary

This trial tests whether a bleaching gel fortified with tiny titanium oxide particles can whiten teeth better and cause less sensitivity than a standard gel. Sixty adults with tooth discoloration will receive either the nano-enriched gel or the conventional gel during a single session. Researchers will measure color change with a spectrophotometer and track pain scores over several days.

What this could mean

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

Active substance
A bleaching gel enriched with titanium oxide nanoparticles derived from corn hair fibers, compared with a conventional hydrogen peroxide gel without nanoparticles.
What this could lead to
If it works, this could offer a way to whiten teeth more effectively while causing less post-treatment sensitivity.
What could go wrong
This is a small, early-stage trial, so results may not apply broadly. The nano-enriched gel might not outperform the standard gel, and some tooth sensitivity is still possible.
