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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 looks at a dental procedure called deep margin elevation (DME) for fixing cavities that go below the gum line. Researchers want to see if placing the filling slightly deeper than usual is safe for the gums and tooth nerve. They will treat 81 adults with deep cavities and check gum health, tooth health, and filling quality over time.

What this could mean

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

Active substance
Deep Margin Elevation (a dental procedure using composite filling material)
What this could lead to
If successful, this could show that dentists can repair deep cavities without needing more invasive gum surgery, preserving tooth and gum health.
What could go wrong
This is a small, non-randomized trial with only 81 participants, so results may not apply to everyone. The procedure might still cause gum inflammation or other issues long-term.

Study facts

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 81 people

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

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

Inclusion Criteria: * Patients at least 18 years of age at the time of treatment. * Permanent Posterior teeth exhibiting proximal caries lesion extending subgingivally below the cemento-enamel junction (CEJ). The axial extent of the caries should not be more than 75% of the dentin thickness. * Sound tooth structure of atleast 1mm should be present from the alveolar crest to the base of the cavity/ gingival seat after cavity preparation. * The tooth should either be asymptomatic or have reversible pulpitis as determined by history and pulp sensibility testing. There should be no history of spontaneous or lingering pain * Periodontally sound tooth * Full mouth plaque score (FMPS): ≤ 15% and Full mouth bleeding score (FMBS): ≤15% Exclusion Criteria: * Presence of bone disease (metabolic, endocrine, infectious, tumoral, developmental pathologies) * Pregnant or lactating and history of smoking or alcohol abuse * Anti inflammatory drug consumption within past 3 days * Uncontrolled or poorly controlled diabetes * Unstable Life threatening conditions or requiring antibiotic prophylaxis. * Presence of detectable plaque and Bleeding on probing on the tooth to be treated * Thin gingival biotype, Periodontitis and Gingival recession * Class II cavities with gingival margin above the CEJ * Previously restored teeth * Absence of adjacent tooth or antagonist or Crown in adjacent tooth. * H/o Bruxism, Xerostomia * Requiring gingivectomy * Isolation with rubber dam not possible
