Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 12 to 99 years
  • All sexes
  • Healthy volunteers accepted
  • Child, Adult, Older adult

Who may be able to join

  • Maxillary or mandibular first or second mature permanent molars with carious lesions or restorations (excluding crowns), with signs and symptoms of symptomatic irreversible pulpitis (defined as spontaneous pulpal pain and cold hyperalgesia >30 seconds), and normal apical tissues.
  • Tooth is responsive to cold and electrical pulp testing.
  • Patients aged ≥12 years for first molars and ≥16 years for second molars.

Who cannot join

  • Evidence of Pulp Necrosis or Apical Periodontitis, preoperatively or upon inspection of an exposure site
  • Teeth that are badly broken down and/or are not restorable.
  • Teeth with mechanical allodynia assessed by registering bite force that is at least 50N lower than the contralateral side.
  • Teeth with radiographic evidence of internal, or external cervical, inflammatory or replacement root resorption, or with complete pulp canal obliteration.
  • Radiographic evidence of PDL space wider than three times normal width
  • Clinical evidence of swelling or sinus tract
Show all 17Show fewer
  • Periodontal pocket probing depth ≥5 mm in any site around the tooth.
  • Clinical evidence of cracks connecting mesial and distal surfaces and/or extending in pulp chamber or associated with periodontal pockets ≥ 5 mm.
  • History of taking centrally acting drugs (e.g., tricyclic antidepressants), which interfere with the release of pain mediators and/or modify pain experience, within the previous 6 months.
  • Use of medications that affect the host response such as methotrexate, corticosteroids or cyclosporin.
  • Patients on immunosuppressive agents, chronic corticosteroid use, autoimmune disease, or other immunocompromising diseases or medications.
  • Patients who require IV sedation or general anesthesia for their dental treatment.
  • Teeth with full coverage crowns.
  • Teeth undergoing active orthodontic movement.
  • Teeth that require elective RCTx to place a post for restorative purposes.
  • Teeth with no contralateral molars with normal pulp and periapical tissues for bite and pulp testing controls.
  • Teeth in the pulpotomy group in which, following complete pulpotomy, bleeding does not stop after 10 minutes with 3-4% hypochlorite cotton pellet. These will be considered treatment failure and treated with RCTx.

About this study

This project addresses a central question within the practice of dentistry: Is a pulpotomy procedure effective in the treatment of a tooth with symptomatic irreversible pulpitis and normal periapex? In addition, the project seeks to identify clinical and molecular biomarkers that are predictive of the success of pulpotomy.

Read the detailed description

In this study, patients will be randomized to two groups. All patients will have a diagnosis of irreversible pulpitis with normal apical tissues. The groups will be root canal treatment and pulpotomy. The patients will be followed clinically and radiographically for 2 years following the treatment. Predictors of the outcome of pulpotomy will be clinical and laboratory-based parameters.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • RCTProcedure or surgery

    Also called Endodontic therapy

    This is the standard of care for this diagnosis

  • PulpotomyProcedure or surgery

    Also called Therapeutic pulpotomy

    For cases with normal apical tissues, pulpotomy using tricalcium silicates has been shown to have high clinical success. Either partial or complete pulpotomy will be performed depending on the size of pulp exposure.

Root canal treatment (RCT)Active comparatorFor cases with this diagnosis RCT is the standard of care and will be done according to clinically approved protocols
Receives: Procedure: RCT
PulpotomyExperimentalPulpotomy with tricalcium silicates has shown high clinical success in these cases. However, it is not known how this success compares to RCT under similar conditions and with an intent-to-treat study design, which will be employed here.
Receives: Procedure: Pulpotomy

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of patients with a successful outcome of pulpotomy versus RCT

    A composite of clinical and radiographic findings and incidence of follow up procedures

    Measured: From baseline through 2 years

Secondary outcomes (2)
  1. Determine prognostic validity of preoperative hyperalgesia in determining the outcome of pulpotomy

    Neurosensory measurements of preoperative signs and symptoms will be measured and correlated with the outcome of pulpotomy

    Measured: From baseline to two years

  2. Determine prognostic validity of a set of pulpal inflammatory proteins in determining the outcome of pulpotomy

    Protein analysis at the time of treatment will be correlated with the outcome of pulpotomy

    Measured: From baseline to 2 years

Questions about this trial

What is this clinical trial studying?

A study testing RCT and Pulpotomy in people with Irreversible Pulpitis, run by University of Alabama at Birmingham at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 17 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Sheila Turner, DDS ((205) 934-5045, jordan@uab.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of patients with a successful outcome of pulpotomy versus RCT (time frame: From baseline through 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2026.
