About this study

Patients presenting to the University of Nebraska Medical Center College of Dentistry for a posterior extraction will be offered participation in the study. Prior to extraction, subjects will undergo clinical measurements, xray, gingival crevicular fluid (GCF) and saliva sampling and a blood draw. Following atraumatic tooth extraction, the subjects will be reevaluated for healing at 1, 2-weeks and 3 months. At each appointment, GCF, saliva and wound fluid (WF) will be collected and at 3 months a second xray will be taken.

Questions about this trial

What is this clinical trial studying?

An observational study of Wound Healing, run by University of Nebraska at 1 site in United States.

The full registered description is in the About this study section and the official record.

How can a doctor refer a patient or contact the research team?

Contact Amy Killeen, DDS, MS (4024727848, akilleen@unmc.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Amount of Interleukin-1 beta (IL1-B) in gingival crevicular at baseline (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07796269, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Sep 2026; AzTrials last refreshed its copy on 29 Oct 2026.
