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.

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 Results may not be published yet.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.

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 whether a toothpaste made with nano-hydroxyapatite can help children aged 6-12 who have a condition called Molar-Incisor Hypomineralization (MIH), which causes weak, discolored, and sensitive teeth. Sixty children will use either the nano toothpaste or standard fluoride toothpaste for 9 months. Researchers will check if the new toothpaste reduces pain from cold air and improves tooth color compared to the standard option.

What this could mean

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

Active substance
nano-hydroxyapatite toothpaste
What this could lead to
If it works, this could offer a simple, non-invasive way to manage tooth sensitivity and discoloration in children with MIH.
What could go wrong
This is a small, early-stage trial with only 60 children, so results may not apply to everyone. The toothpaste may not outperform standard fluoride toothpaste.
