What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

Summary

Researchers compare two ways to repair hypomineralised second primary molars, a condition where enamel on baby teeth is soft and breaks down. Thirty children aged 5 to 10 receive either an orthodontic band with glass ionomer cement or a preformed stainless steel crown placed using the Hall technique. The team checks how well each restoration fits, stays in place, and prevents new cavities over 18 months, and asks children and caregivers how acceptable the treatment is.

What this could mean

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

Active substance
orthodontic band restorative treatment
What this could lead to
If orthodontic bands hold up as well as steel crowns, dentists could have a simpler, less invasive option for repairing damaged baby molars in young children.
What could go wrong
This is a small trial of 30 children at one dental school, so the results may not apply to all children or all dentists. Bands can come loose or leak, and the study may not show a clear difference between the two methods.

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.

Participants

About 30 people

The number the study aims to enrol. It can still change while the study runs.

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.

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

Inclusion Criteria: * Children aged 5-10 years. * Presence of at least one second primary molar affected by hypomineralised second primary molars requiring restorative treatment. * Hypomineralisation associated with post-eruptive enamel breakdown involving more than one tooth surface or a cavitated carious lesion involving more than one surface and classified as code 5 or 6 according to the International Caries Detection and Assessment System. Exclusion Criteria: * Extensive carious lesion with subgingival margins. * Clinical or radiographic signs of pulpal inflammation or necrosis. * Advanced physiological root resorption indicating imminent exfoliation of the eligible tooth. * Previous restorative treatment of the eligible tooth. * Presence of bruxism.
