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 This study
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 Results may not be published yet.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

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 compares three oral hygiene routines in 90 adults aged 60+ who have gum disease and mild cognitive impairment. One group uses a special light device (Lumoral) plus a manual toothbrush, another uses a powered toothbrush (Oral-B iO), and a control group uses a manual toothbrush. Over six months, researchers will measure plaque, gum bleeding, pocket depth, bad breath, and quality of life to see which approach works best.

What this could mean

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

Active substance
dual-light antibacterial photodynamic therapy (aPDT) device (Lumoral) and Oral-B iO powered toothbrush
What this could lead to
If successful, this could show that simple home-use devices can improve gum health and quality of life in older adults with memory problems.
What could go wrong
This is a small, early-stage trial with only 90 participants, so results may not apply to everyone. The improvements may be modest and not lead to long-term benefits.
