Periodontal DiseaseNCT01376791
Assess the Effect of Treating Periodontal Disease on Cardiovascular Function in Young Adults
An observational study of Periodontal Disease and Atherosclerosis, run by San Diego State University at 1 site in United States.
Trial summary
We propose to examine a population of Native Americans who have had little or no dental care, and to determine if periodontal disease is associated with early signs of vascular dysfunction or systemic inflammation. We then propose to treat the periodontitis and re-evaluate vascular function. Read more about this study

About this study
Official title: Oral Flora, Periodontitis, and Vascular Dysfunction in Young Native Americans.
We propose to examine a population of Native Americans who have had little or no dental care, and to determine if periodontal disease is associated with early signs of vascular dysfunction or systemic inflammation. We then propose to treat the periodontitis and re-evaluate vascular function. We will determine if gingivitis or mild/moderate periodontitis is associated with detectable vascular dysfunction. Microbial metagenomics will be correlated with vascular function.

What is being measured
The primary outcome is the main question the study is designed to answer.
Determination of bacterial populations in periodontal samples before and after standard periodontal treatment, stratified by severity of gum disease, using microbial metagenomics analysis.
The study will assess if periodontal bacterial flora differ in patients with healthy gums, mild, or severe periodontal disease.
Measured: Time of enrollment and at 6 week follow up visit

Questions about this trial
What is this clinical trial studying?
An observational study of Periodontal Disease and Atherosclerosis, run by San Diego State University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Determination of bacterial populations in periodontal samples before and after standard periodontal treatment, stratified by severity of gum disease, using microbial metagenomics analysis. (time frame: Time of enrollment and at 6 week follow up visit). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 23 Apr 2013; AzTrials last refreshed its copy on 7 Nov 2026.
