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 Results may not be published yet.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

This study looks at whether a type of gum surgery called esthetic crown-lengthening can provide lasting results for people with a gummy smile caused by altered passive eruption. Ten adults with excessive gingival display will undergo the procedure, which involves removing excess gum tissue and reshaping the underlying bone. Researchers will track changes in gum position, bone levels, and patient satisfaction for up to 12 months to see if the improvements hold.

What this could mean

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

Active substance
Esthetic crown-lengthening surgery (gingivectomy and osseous recontouring)
What this could lead to
If successful, this could establish a reliable surgical approach for correcting excessive gingival display, improving smile aesthetics and patient satisfaction.
What could go wrong
This is a small early-stage study with only 10 participants, so results may not apply broadly. Surgery carries risks like swelling, discomfort, or tissue changes that may not be stable over time.

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: * Adults with an esthetic complaint related to excessive gingival display. * Diagnosis of altered passive eruption as one of the etiologic factors associated with excessive gingival display. * Altered passive eruption involving the alveolar bone. Exclusion Criteria: * Current orthodontic treatment. * Active periodontal disease. * Systemic conditions that contraindicate periodontal surgical procedures, including uncontrolled autoimmune diseases. * Use of medications that may interfere with the inflammatory response or wound healing, including corticosteroids or immunosuppressive agents. * Current smokers. * Former smokers who discontinued smoking less than 12 months before enrollment. * Pregnant or breastfeeding individuals. * Excessive gingival display primarily associated with lip hypermobility or vertical maxillary excess without concomitant altered passive eruption.
