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 This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study compares two treatments for severely damaged upper molars: root amputation (removing only the damaged root and keeping the rest of the tooth) versus replacing the whole tooth with a dental implant. Researchers will track pain, bone healing, and implant stability over 12 months in 28 patients. The goal is to help dentists choose the best option for saving teeth.

What this could mean

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

Active substance
root amputation (surgery) and dental implant
What this could lead to
If successful, this could show that root amputation is a good alternative to implants for saving damaged upper molars, helping more people keep their natural teeth.
What could go wrong
This is a small, early study with only 28 participants, so results may not apply to everyone. Both procedures have risks like infection or failure, and the study hasn't started yet.

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 28 people

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

Expected to start

Jan 2027

An estimate. Start dates often move.

Expected to finish

Jan 2028

An estimate. End dates often move.

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

21 to 60 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Show the full entry requirements

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

Inclusion Criteria: * Patients will be illegible for root amputation if they one or more of the following criteria: * Severe vertical bone loss affecting only Mesio-buccal root of Maxillary molar. * Through-and-through furcation involvement * Vertical root fracture confined to a Mesio-buccal root of Maxillary molar. * Extensive root caries affecting Mesio-buccal root of Maxillary molar. * Endodontic failure or non- treatable perforation in Mesio-buccal root of Maxillary molar * Extensive internal or external non- treatable root resorption related to Mesio-buccal root of Maxillary molar. * Patients who do not meet the above criteria and present with Maxillary molars in more severely compromised conditions will be directed for extraction followed by dental implant placement. Exclusion Criteria: * \- Uncontrolled systemic disease, immunosuppression, recent bisphosphonate use, head and neck radiotherapy. * Patient non-compliance or poor oral hygiene. * Heavy smoking or inability to commit to maintenance. * Root anatomy or interradicular bone that precludes predictable root amputation; insufficient bone for implant placement that cannot be reasonably augmented.
