What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
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 Results may not be published yet.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
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This study compared two treatments for severely decayed baby molars in children aged 4 to 9. One group received a pulpotomy, where only the infected part of the tooth's nerve is removed and replaced with a special cement (Biodentine). The other group had a full pulpectomy, removing all nerve tissue and filling the canals with a medicated paste (Metapex). The goal was to see if the simpler pulpotomy works as well as the more involved pulpectomy in preserving the tooth and preventing pain or infection.

What this could mean

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

Active substance
Biodentine (calcium silicate cement) and Metapex (calcium hydroxide iodoform paste)
What this could lead to
If successful, this could show that a less invasive pulpotomy with Biodentine is a good alternative to full pulpectomy for treating infected baby teeth in children.
What could go wrong
This is a small, completed trial with only 28 participants, so results may not apply to all children. The study also excludes teeth with severe symptoms, limiting its scope.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

4 to 9 years

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * • Patient and parent showing cooperation and compliance. * Children 4-9 years old * Vital deeply carious primary(s) with complete root formation * Asymptomatic teeth or without clinical symptoms of spontaneous pain * No clinical evidence of pulp degeneration like the history of spontaneous or nocturnal pain, tenderness to percussion, pathologic tooth mobility, swelling, or fistulous tract. * Both genders will be included. * No radiographic evidence of pulp degeneration such as internal root resorption, external root resorption, or furcal radiolucency. * Presence of 2/3rd of root * Teeth that can be restored * Children with prior parental consent. Exclusion Criteria: * • soft tissue inflammation. * tooth mobility. * sinus tract. * Any radiographic sign of periapical pathologies or pulp necrosis (periapical radiolucency, internal or external root resorption) * History of any systemic disease * Teeth showing clinical or radiographic evidence of pulp degeneration * Hemostasis not achieved within 5 minutes of pulp amputation, by direct contact with a wet cotton pellet before the material placement * The remaining radicular tissue was non-vital (with suppuration or purulence necrosis)
