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.

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 compares three types of dental filling materials for repairing non-carious cervical lesions (tooth damage not caused by cavities). Thirty-three adults with at least three such lesions will receive each material in different teeth. Over two years, dentists will rate how well each filling looks and functions. The goal is to find which material performs best.

What this could mean

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

Active substance
dental restorative materials (alkasite-based, hybrid resin composite, flowable resin composite)
What this could lead to
If successful, this could identify which dental material works best for repairing tooth lesions, improving long-term dental restoration choices.
What could go wrong
This is a small, early-stage trial with only 33 participants, so results may not apply to everyone. The materials may perform differently in real-world use.

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.
