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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are testing whether showing patients a diagram of wisdom tooth removal steps before surgery reduces their psychological stress. The trial measures stress by checking salivary cortisol levels before and after the procedure in healthy adults. Half of the participants will see the illustration, while the other half will not. The study also tracks how long the surgery takes to see if less stress leads to smoother procedures.

What this could mean

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

Active substance
Presurgical diagrammatic illustration of mandibular third molar surgery
What this could lead to
If it works, showing a simple diagram before surgery could become a low-cost way to ease patient anxiety in dental and other surgical settings.
What could go wrong
This is a small, early trial with 80 participants, and stress is measured indirectly through saliva. The diagram may not reduce stress for everyone, and results may not apply beyond this specific surgery.

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

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.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Healthy patients (American Society of Anesthesiologists Class I), * Patients demanding extraction of their mandibular third molar, * Mandibular third molars requiring flap raising, bone removal, coronal and radicular sectioning (Modified Parant Scale Class IV), * Patients accepting their saliva sampling prior to and after surgery.
