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 Results may not be published yet.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

Summary

This trial compares two types of ceramic veneers—ultra-translucent zirconia and lithium disilicate—in 10 adults aged 18–50. The goal is to see which one looks better, lasts longer, and makes patients happier. Participants must have healthy gums and teeth needing veneers for gaps, discoloration, or shape issues. Results will help dentists choose the best material for front-tooth restorations.

What this could mean

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

Active substance
dental veneer (ultra-translucent monolithic multi-layered zirconia or lithium disilicate ceramic)
What this could lead to
If successful, this could show that ultra-translucent zirconia veneers are a good alternative to standard lithium disilicate veneers for fixing tooth color, shape, or gaps.
What could go wrong
This is a very small early trial with only 10 people, so results may not apply to everyone. Bonding zirconia to teeth can be tricky, and long-term durability is still unknown.
