Summary

The goal of this randomized clinical trial is to compare the clinical performance of three pulp capping materials used in full pulpotomy procedures in mature mandibular molars with symptomatic irreversible pulpitis.

The main questions it aims to answer are:

* Does full pulpotomy using mineral trioxide aggregate (MTA) provide favorable postoperative pain control and 12-month clinical success?
* Does full pulpotomy using TheraCal LC provide comparable postoperative pain control and 12-month clinical success to MTA?
* Does full pulpotomy using TheraCal PT provide comparable postoperative pain control and 12-month clinical success to MTA?

Participants will undergo full pulpotomy treatment in mandibular first or second molars diagnosed with symptomatic irreversible pulpitis. After removal of the coronal pulp tissue and achievement of hemostasis, teeth will be randomly assigned to one of three treatment groups.

In the MTA group, the exposed radicular pulp tissue will be covered with mineral trioxide aggregate.

In the TheraCal LC group, the exposed radicular pulp tissue will be covered with light-cured resin-modified calcium silicate material.

In the TheraCal PT group, the exposed radicular pulp tissue will be covered with dual-cured resin-modified calcium silicate material.

Postoperative pain intensity, analgesic intake, and 12-month clinical outcomes will be compared among the three groups.

Conditions

  • Pulpitis - Irreversible

Interventions

OTHER

Mineral Trioxide Aggregate (MTA)

In the MTA group, after full pulpotomy and achievement of hemostasis, the exposed radicular pulp tissue was covered with mineral trioxide aggregate. The material was placed over the pulp surface at a thickness of approximately 2-4 mm and gently condensed.

OTHER

Theracal LC

In the TheraCal LC group, after full pulpotomy and achievement of hemostasis, the exposed radicular pulp tissue was covered with TheraCal LC, a light-cured resin-modified calcium silicate material. The material was applied in increments not exceeding 1 mm, and each increment was light-cured for 20 seconds.

OTHER

TheraCal PT

In the TheraCal PT group, after full pulpotomy and achievement of hemostasis, the exposed radicular pulp tissue was covered with TheraCal PT, a dual-cured resin-modified calcium silicate material. The material was applied as a single layer at a thickness of approximately 2-3 mm and light-cured for 20 seconds.
