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 Results may not be published yet.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.

Summary

This study tested a new pain scoring tool to help dentists tell apart reversible and irreversible pulpitis, a common diagnostic challenge. Researchers enrolled 143 patients with tooth pain and compared the tool's results with two standard classification systems. The goal was to see if the scoring system could improve diagnostic accuracy and predict post-treatment pain.

What this could mean

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

What this could lead to
If successful, this scoring system could help dentists more accurately diagnose pulpitis, leading to better treatment choices and less unnecessary root canals.
What could go wrong
This is a completed observational study, not a treatment trial. The tool may not work for all patients or dentists, and more research is needed before widespread use.

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

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.

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

18 years and older

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

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

Inclusion Criteria: Patients aged 18 years or older presenting with acute symptoms associated with a single tooth exhibiting vital pulp tissue, without clinical or radiographic evidence of periapical pathology, and who consented to participate were included. Exclusion Criteria: Exclusion criteria comprised pulpal necrosis, previously root canal-treated teeth, periapical pathology unrelated to pulpal disease, regular use of analgesic or anti-inflammatory medications, pregnancy, immunosuppressive conditions, and systemic diseases that could interfere with pain perception, healing, or follow-up compliance.
