What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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 compares three ways to match the shade of a tooth for a filling: a new computer software that analyzes dental photos, a digital spectrophotometer, and the traditional visual method. Researchers will enroll 52 adults with healthy front teeth to see which method agrees most with the actual shade. The goal is to find a more accurate and reliable technique for dental restorations.

What this could mean

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

Active substance
Computer-assisted photo-analysis software and digital spectrophotometer
What this could lead to
If successful, this software could provide a more objective and consistent way to match tooth shades for dental restorations.
What could go wrong
This is a small, early-stage study. The software may not outperform the traditional visual method in real-world dental practice.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 52 people

The number the study aims to enrol. It can still change while the study runs.

Started

May 2026

Expected to finish

Oct 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 45 years

Sex

Anyone

Healthy volunteers

Not accepted

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