Completed This study
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 Results may not be published yet.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 tested three biocompatible materials—TheraCal PT, Biodentin, and MTA—for reducing pain after a pulpotomy (removing the inner pulp) in 51 adults with severe toothache. Participants rated their pain before and up to 7 days after treatment. The goal is to find which material offers the best pain relief to guide dentists' choices.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
TheraCal PT, Biodentin, and MTA (dental materials used in pulpotomy)
What this could lead to
If one material proves better at reducing pain, dentists may have a clearer choice for managing discomfort after this common dental procedure.
What could go wrong
This is a small, completed trial with only 51 participants, so results may not apply to everyone. Pain is subjective and hard to measure precisely.
