Intentional Pulpotomy to Preserve Hopeless Molars

June 5, 2023 updated by: University of Florida

Intentional Pulpotomy to Preserve Vital Primary Molars With Challenging Restorability: a Feasibility Study

When proximal carious lesions of primary molars are located in close proximity to the cementum enamel junction (CEJ), marginal seal is challenging and extraction is recommended. Pulpotomy is indicated for vital primary teeth to preserve them in function. The goal of this study is to monitor the long-term effect of intentional bioactive cement pulpotomies and crown coverage performed on vital and asymptomatic carious primary molars with gingival margins close to or at the CEJ

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.

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

5 years to 10 years (Child)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Selected patients will have one or more primary molar teeth diagnosed clinically with large proximal carious lesions with the gingival extension of the cavity at or below the cemento-enamel junction. The tooth should be asymptomatic and must have no signs of swelling, fistula, abnormal mobility and sensitivity to percussion (ruling out food impaction), and adequate space for placement of a stainless steel crown restoration. The pre-operative periapical radiograph, taken as part of the new patient/recall routine visit, should reveal a lesion in close approximation to the pulp, but having at least 1-2 mm of sound dentin separating the deepest portion of the lesion and the pulp. In addition, no evidence of furcation and periapical pathology, internal or external root resorption and presence of half to two-thirds of root length remaining.

Exclusion Criteria:

  • Uncooperative patients
  • Teeth with positive history of pain, abnormal mobility, signs of pulp necrosis such as presence of swelling or fistula, and significant space loss due to caries not allowing placement of a stainless steel crown restoration
  • Radiographically, signs of furcation and periapical pathology, internal and external resorption, less than half to 2/3 of root length remaining
  • Selected patients will be treated by pediatric dental residents in the regular dental clinic setting with or without nitrous oxide inhalation, as part of the standard of care
  • Prior to the beginning of the study, all operators will be calibrated by the principal investigator on identifying the teeth in question, as well as on the restorative technique
  • Selected patients may have one or more qualified teeth

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Pulpotomy
Group A: The patient will benefit from an experimental treatment: a Pulpotomy. The pulpotomy aims at removing the coronal part of the pulp (the pulp present in the pulp chamber) and filling the pulp chamber with a bioactive material.
Procedure: Pulpotomy
Pulpotomy using bioactive bioceramic cement of 1.5 mm layer of a newly FDA approved calcium-based silicate cement (Nusmile NeoPutty) will be placed on the pulp chamber floor and canals' orifices for pulp and root therapy. Pulpotomy is a procedure in which the coronal pulp is amputated, and the remaining radicular pulp tissue is treated with a medicament to preserve the pulp's health.This technique involves administration of local analgesia, Isolation of the tooth with rubber dam, complete caries removal and then access to the pulp chamber using drills.
Active Comparator: Control Group
Group B: Extracted teeth will serve as controls, and information regarding the need or not of space maintenance, and the impact on the occlusion and eruption of the succedaneous permanent tooth will be noted.
Procedure: Extraction and placement of space maintainer
If during the pulpotomy procedure, hemostasis is not obtainable, or signs of advanced pulp degeneration such as dark and limited or no bleeding from canals, the pulp will be diagnosed as chronically inflamed or necrotic, and tooth will be extracted. As part of the standard of care after extractions of primary molars, space maintenance will be assessed, and a space maintainer fabricated if indicated. Extracted teeth will serve as controls, and information regarding the need or not of space maintenance.
