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 Results may not be published yet.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
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.

Summary

This study tests whether using a dental operating microscope during a pulpotomy (a partial root canal) reduces pain and improves quality of life afterward. 82 adults with deep cavities and tooth nerve pain will be randomly assigned to get the procedure with or without the microscope. Pain levels and daily-life impact will be tracked for 72 hours after treatment.

What this could mean

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

Active substance
dental operating microscope (device)
What this could lead to
If it works, this could show that using a microscope during a common dental procedure reduces pain and improves recovery for patients with deep cavities.
What could go wrong
This is a very early-stage trial with only 82 participants, so results may not apply to everyone. The microscope may not significantly reduce pain compared to standard care.

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 aged at least 18 years old with deep or extremely deep carious lesions in mature permanent teeth diagnose with symptomatic irreversible pulpitis. Diagnoses are confirmed using EPT and cold tests. Pulpal and periapical diagnoses are based on terminology from the American Association of Endodontists (AAE, 2013)20. * Posterior teeth with moderate or severe pain according to The NRS (Numeric Rating Scale) According to this scale, the level of pain is documented in the range of 0-10 numerically and verbally as no pain (0), mild pain, non-disruptive to routine activities (1-3), moderate pain that interferes with daily life but no need analgesics intake (4-6) and severe pain that significantly disrupts normal acitivities requiring analgesic intervention (7-10). * Teeth that response negatively to percussion and palpation tests. * Teeth are restorable with direct composite restoration. Exclusion Criteria: * Teeth with subgingival caries and/or clinical attachment loss more than 3 mm and probing depth more than 4 mm. * Negative responses to pulp sensibility tests, presence of sinus tracts, swelling, non-restorable crowns, immature roots, or no pulp exposure following complete caries removal in case of pre-operative diagnosis as asymptomatic irreversible pulpitis. * Patients with systemic diseases involving bleeding disorders such as hemophilia, Von Willebrand disease, platelet disorders. And patients under taking all kind of anticoagulant and anti-platelet. * Patients who had taken analgesics or anti-inflammatory drugs within the previous 24 hours. If necessary, record how many and dose that taken. * Patients taking opioids. * Known allergies to non-steroidal anti-inflammatory drugs (NSAIDs). * Pregnant or lactating patients. * Teeth with pulpal obliteration. * Necrotic pulp is found after access opening * Bleed cannot be stopped within 8 minutes after full pulpotomy
