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.

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.

Summary

This study looks at how fixed versus removable orthodontic retainers influence the types of bacteria living in the gum pockets and overall gum health. Ten adults who have finished braces will be split into two groups: one gets a fixed retainer bonded to the back of the teeth, the other gets a clear removable retainer worn 22 hours a day. Researchers will collect plaque samples and measure gum bleeding at five visits over six months to see if one retainer type leads to healthier gums and a better bacterial balance.
