Evaluation of Regenerative Endodontic Treatment for Immature Teeth

September 29, 2025 updated by: Hisham Mahmoud Hamdy Abada, Kafrelsheikh University

Evaluation of Regenerative Endodontic Treatment for Immature Teeth Using Two Different Forms of Demineralized Dentin Matrix and RetroMTA: Randomized Controlled Clinical Trial

The goal of this clinical trial is to evaluate if regenerative endodontic treatment using two different forms of demineralized dentin matrix (DDM) can effectively treat immature permanent single-rooted teeth compared to treatment using RetroMTA in patients aged 9 to 15 years. The main questions it aims to answer are:

Does the use of DDM improve clinical and radiographic outcomes such as root length, dentinal wall thickness, and apex closure?

Is DDM a viable bioactive alternative to RetroMTA as a coronal sealing material in regenerative endodontic procedures?

Researchers will compare three groups: one using RetroMTA, one using a DDM-TheraCal LC mixture, and one using TDM-Hydrogel, to see if these materials differ in their effects on regenerative outcomes.

Participants will:

Undergo two treatment visits including canal disinfection, induction of bleeding to form a blood clot scaffold,

Receive placement of one of the study materials over the blood clot as a coronal barrier,

Have clinical examinations and CBCT imaging at baseline and multiple follow-ups up to 12 months to assess treatment success through signs, symptoms, and radiographic changes.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study was conducted as a split-mouth randomized clinical trial, approved by research ethics committee, Faculty of Dentistry, Kafrelsheikh University, and carried out at Endodontic Department, Faculty of Dentistry, Kafrelsheikh University. 36 patients of both sexes aged from 9 to 15 years old were selected with an immature teeth with teeth diagnosed as either vital (asymptomatic irreversible pulpitis or symptomatic irreversible pulpitis and the bleeding didn't stop after 5 minutes application of hemostatic agent) or non-vital pulp are indicated for regenerative endodontic procedure.

Patients will be divided randomly into three equal groups (n = 12):

Group 1(control group): Revascularization will be done using blood clot and RetroMTA as coronal barrier.

Group 2: Revascularization will be done using blood clot and DDM-TheraCal LC mixture paste as coronal barrier.

Group 3: Revascularization will be done using blood clot and TDM-Hydrogel as coronal barrier.

CBCT image will be obtained for baseline records before treatment and after placement of the final resin restoration, then the patients will be recalled after 3, 6, 9 and 12 months for evaluating any changes in dentin bridge formation, root length, root canal width, apex diameter and lesion size if present.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child

Inclusion Criteria:

  • Systemically healthy patients (i.e., free of any systemic diseases).
  • Patients presenting with immature permanent single-rooted teeth.
  • Age: 9 -15 years.
  • Teeth diagnosed as either vital (asymptomatic irreversible pulpitis or symptomatic irreversible pulpitis and the bleeding didn't stop after 5 minutes application of hemostatic agent) or non-vital pulp.

Exclusion Criteria:

What is the study measuring?

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
