What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Ongoing This study
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 Results may not be published yet.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

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 compares three modern dental materials used to treat deep cavities in children's permanent molars by preserving the tooth nerve. The goal is to see which material best helps the tooth root continue growing and reduces pain. About 48 healthy children aged 7 to 11 with one affected molar will be followed for 12 months.

Inclusion Criteria: * -Healthy patients (according to ASA classification) with noncontributory medical history. * Patients aged between 7 and 11 years of age, with at least one immature permanent molar with deep caries, needing full pulpotomy. * Cooperative pediatric patients (Frankl's behavioral rating scale). * Restorable immature permanent molar with deep caries: caries involving the pulpal roof or where complete caries removal would likely result in pulpal exposure. * Physiological mobility. * Vital pulp (detected by clinical signs/symptoms) presenting symptoms classically indicative of irreversible pulpitis according to AAE diagnostic criteria : positive but heightened response to cold sensibility testing, presence of spontaneous pain. * No clinical signs of pulp necrosis; absence of a sinus tract or swelling. * Patients who agree to return for periodic examination (follow-up). * Patients who are willing to sign the consent form (written informed consent). Exclusion Criteria: * -Medically compromised patients. * Patients older than 11 years or younger than 7 years of age. * Mature permanent molar. * No signs and symptoms of irreversible pulpitis. * No pulp exposure even after complete caries excavation. * Clinical signs of pulp necrosis on the tooth to be treated, such as insufficient bleeding or no bleeding after pulp exposure. * Uncontrollable pulp hemorrhage (more than 10 minutes of hemostasis). * Teeth previously endodontically treated. * Teeth with pathological root resorption. * Impossibility to place a rubber dam.
