Clinical Trial of Two Techniques for Gingival Displacement (NCT01848496) | Clinical Trial Compass
CompletedPhase 1
Clinical Trial of Two Techniques for Gingival Displacement
Brazil22 participantsStarted 2012-01
Plain-language summary
Regardless of the selected technique for dental impression, gingival displacement is an essential procedure specially when making impressions of subgingival finishing lines, because a moisture-free sulcus is a requirement for an effective impression.
The objective of this randomized clinical study is to evaluate the efficacy of the conventional and cordless gingival displacement (GD) techniques.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial was testing two different techniques for gingival displacement — which means moving gum tissue away from a tooth before making a dental impression — so could you explain what each technique involved and how they might relate to restoring my tooth?
2Since this was a Phase 1 trial focused on measuring interleukin levels in the fluid around the gum line, what does that tell us about how much is known so far regarding the safety and tissue effects of these two displacement techniques?
3The trial measured inflammatory markers called interleukins in the gingival crevicular fluid — does that mean one technique may cause more gum inflammation than the other, and how would that affect my recovery or the quality of my restoration?
4Now that this trial is completed, have the results been published, and could you help me understand what they found about how each technique affected the gum tissue around the tooth being restored?
5Before considering any experimental approach, would standard gingival displacement methods already available in your practice be a more appropriate first step for improving the appearance of my existing restoration?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
