What the study statuses mean

This study's is highlighted.

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.
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 Results may not be published yet.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
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial explores whether a program of pranayamic breathing techniques and tongue exercises can alter the oral microbiota—the community of bacteria in the mouth—in children aged 7 to 12. Participants, grouped by whether they breathe through their mouth or nose, will follow the exercise program for 8 weeks. Saliva samples taken before and after will be analyzed to see if bacterial diversity changes. The study aims to shed light on how breathing patterns and oral exercises might influence oral health.

What this could mean

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

Active substance
A structured program of pranayamic breathing techniques, tongue exercises, and, in some groups, tongue cleaning
What this could lead to
If the exercises shift oral bacteria in a beneficial way, this could point toward simple, drug-free habits to support children's oral health.
What could go wrong
This is a small, early exploratory study, so any effects may be modest or not apply broadly. The main measure is a lab test of bacterial diversity, not a direct health outcome.

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

About 80 people

The number the study aims to enrol. It can still change while the study runs.

Started

Mar 2026

Expected to finish

Dec 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

7 to 12 years

Healthy volunteers

Accepted

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

Show the full entry requirements
