PERIODONTITIS AND VASCULAR DYSFUNCTION
A study testing Intensive Periodontal Treatment in people with Periodontitis and Intimal Medial Thickness of Internal Carotid Artery, run by University College, London at 1 site in United Kingdom.
Trial summary
The investigators wish to assess whether intensive periodontal therapy will reduce the burden of chronic periodontal disease and will cause regression or prevent progression of atherosclerosis assessed by a surrogate end-point (carotid intima-media thickness) at 24 months compared to control periodontal therapy.

What is being measured
The primary outcome is the main question the study is designed to answer.
Common Carotid Intima-media Thickness (cIMT)
Assess whether intensive periodontal therapy will cause regression or prevent progression of atherosclerosis assessed by carotid intima-media thickness at 24 months compared to standard periodontal therapy.
Measured: cIMT will be assessed at Baseline, 12 and 24 months after periodontal treatment
Secondary outcomes (5)
Brachial artery Flow-mediated dilatation (FMD)
Assess whether pre-treatment (24hrs before) with remote ischaemic pre-conditioning will prevent acute inflammatory endothelial dysfunction induced by intensive periodontal treatment
Measured: FMD will be assessed at baseline, 24 hours and 1 week after periodontal treatment
Pulse-wave velocity (PWV)
Assess whether intensive periodontal therapy will cause amelioration of PWV at 12, 18 and 24 months follow up compared to standard periodontal therapy.
Measured: PWV will be assessed at baseline, 2, 6, 12, 18 and 24 months following periodontal treatment
Brachial artery Flow-mediated dilatation (FMD)
Assess whether intensive periodontal therapy will cause amelioration of FMD at 12, 18 and 24 months follow up compared to standard periodontal therapy.
Measured: FMD will be assessed at baseline, 2 , 6 , 12 , 18 and 24 months following periodontal treatment
Blood inflammatory markers
Assess whether intensive periodontal therapy will cause changes in the blood inflammatory markers profile at 2, 6, 12, 18 and 24 months follow up compared to standard periodontal therapy.
Measured: Inflammatory mediators profile will be assessed at baseline, 2, 6, 12, 18 and 24 months following periodontal treatment
Oxidative stress
Assess whether intensive periodontal therapy will cause changes in the oxidative stress profile at 2, 6, 12, 18 and 24 months follow up compared to standard periodontal therapy.
Measured: Oxidative stress profile will be assessed at baseline, 2, 6, 12, 18 and 24 months following periodontal treatment

Questions about this trial
What is this clinical trial studying?
A study testing Intensive Periodontal Treatment in people with Periodontitis and Intimal Medial Thickness of Internal Carotid Artery, run by University College, London at 1 site in United Kingdom.
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 3 inclusion and 6 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 25 Jan 2021. 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 Kingdom. 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. Some participants in this study may receive a placebo. 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?
Common Carotid Intima-media Thickness (cIMT) (time frame: cIMT will be assessed at Baseline, 12 and 24 months after periodontal treatment). 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 NCT03072342, 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 25 Jan 2021.
