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.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.

Summary

This study tested whether a special ultrasonic handpiece that sprays hydroxyapatite (a natural enamel mineral) can reduce tooth sensitivity during dental cleanings for people with gum disease. Forty adults with moderate to severe periodontitis had half their mouth cleaned with the new device and the other half with a standard ultrasonic tool. Researchers measured changes in gum pocket depth and sensitivity over 6 months to see if the new method is more comfortable and effective.

What this could mean

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

Active substance
hydroxyapatite
What this could lead to
If effective, this could offer a gentler, less painful option for dental cleanings in people with gum disease.
What could go wrong
This is a small, completed trial with only 40 participants, so results may not apply to everyone. The improvement in sensitivity may be modest or not last long-term.
