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 Results may not be published yet.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.

Summary

This trial tests how well different tooth color matching methods agree with a reference spectrophotometer. Forty adults will have their front teeth shade assessed by visual inspection, a digital intraoral scanner, and an AI-based system. The goal is to see which method is most accurate and repeatable for choosing tooth shades in cosmetic dentistry.

What this could mean

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

Active substance
Observer-based shade selection, digital intraoral scanner (TRIOS 3), and AI-based color analysis compared to a spectrophotometric system (VITA Easyshade V)
What this could lead to
If digital and AI methods prove accurate, dentists could rely on objective tools for tooth shade matching, improving aesthetic outcomes.
What could go wrong
This is a small, early-stage study; results may not apply broadly, and digital or AI methods might not match the reference standard's accuracy.
