Dental showdown: which pulp treatment works best for kids?
NCT ID NCT07168811
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study will test three different materials—hyaluronic acid, TheraCal, and MTA—used to treat deep cavities in children's baby molars. Sixty-six kids aged 4 to 8 will receive one of the treatments, and researchers will check for pain, swelling, and X-ray changes over 12 months. The goal is to find out which material keeps the tooth healthy longest.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hyaluronic acid, TheraCal, or mineral trioxide aggregate (MTA) applied to the tooth pulp
- What this could lead to
- If successful, this could show that a simpler, less expensive material works just as well as standard treatments for saving baby teeth.
- What could go wrong
- This is a small, early-stage trial with only 66 children, so results may not apply to all kids. Also, any pulpotomy can fail over time, leading to infection or tooth loss.
