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 This study
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 Results may not be published yet.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

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 study tests four different ways to apply a new universal dental adhesive when fixing cavities on the side of teeth. Fifty patients will receive a total of 200 fillings, each using a different application method. The fillings will be checked every six months for four years to see which method keeps the filling in place best and prevents staining or decay.

What this could mean

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

Active substance
Futurabond Universal adhesive system
What this could lead to
If successful, this could identify the best method to apply dental adhesive, making fillings last longer and reducing the need for repeat dental work.
What could go wrong
This is a small, early-stage trial with only 50 patients. Results may not apply to all dental situations, and the study only looks at one type of adhesive.

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

50 people

The number who actually took part.

Started

Sep 2016

Expected to finish

Nov 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 70 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * All patients must have at only 20 teeth in function, must have at only 2 non carious cervical lesions (NCCL), in different teeth, that need restoration. Those lesions must be non carious, must be more than 1 mm deep, should have exposed dentin, and must have at only 50% of margins in enamel. Teeth should not present periodontal mobility. Exclusion Criteria: * Volunteers with periodontal disease; with gingival bleeding; use of anti-inflammatory drugs in the last 30 days.
