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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tested whether using a sonic device (EDDY) during root canal treatment in children's baby molars reduces pain afterward. Thirty children aged 5-8 with tooth infections received either sonic-activated cleaning or standard cleaning. Pain was measured using a face scale and an AI app that analyzed facial expressions. The goal was to see if sonic activation makes treatment more comfortable and if AI can help assess pain.

What this could mean

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

Active substance
EDDY system for sonic activation of irrigation
What this could lead to
If it works, this could make root canal treatments less painful for children and offer a new way to measure pain using AI.
What could go wrong
This is a small, completed study with only 30 children, so results may not apply to all kids. The AI app for facial expressions is still experimental.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Children with positive or definitely positive behavior on the Frankl's behavior rating scale (rating 3 or 4 on the scale). 3.

Exclusion Criteria: 1. Teeth with pathological root resorption. 2. Teeth with mobility greater than 1st-degree mobility. 3. Children who received analgesics and/or antibiotics in the last 12 h before root canal treatment
