Trial summary

This study is being conducted to test the ability and accuracy of a new instrument in the diagnosis of periodontitis (gum disease) by using fluids from the mouth. The diagnosis instrument will test two types of fluids, gingival crevicular fluid (GCF) and saliva. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 80 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: 100 Adult subjects comprised of two populations: 1) disease susceptible (n=50) and 2) low-risk disease (n=50)

Who may be able to join

  • Must possess at least 20 teeth and not have received periodontal treatment or antibiotic-related therapy for medical or dental reasons 3 months prior to study inclusion.
  • Low-risk inclusion: < 3 mm of attachment loss, no pockets > 4 mm, possess no radiographic bone loss, and < 20 sites with bleeding on probing (BOP). Low-risk cohort will be comprised of at least > 50% of the subjects above age 35 in order to exam low risk patients in other age strata (so as to decrease potential bias towards a younger population in the low risk cohort).
  • Disease-susceptible inclusion: Exhibit at least 4 sites with evidence of radiographic bone loss, mean attachment loss > 3 mm, pocket depths (PD) > 4 mm and BOP.

Who cannot join

  • Long-term use of medications known to affect periodontal status such as anti-inflammatory drugs (NSAIDS and aspirins)
  • History of metabolic bone diseases such as rheumatoid arthritis or post-menopausal osteoporosis.

About this study

This study is being conducted to test the ability and accuracy of a new instrument in the diagnosis of periodontitis (gum disease) by using fluids from the mouth. The diagnosis instrument will test two types of fluids, gingival crevicular fluid (GCF) and saliva. GCF is the fluid that accumulates between your teeth and gum tissue. The fluids will be collected in three ways: 1. Direct GCF sampling 2. GCF rinse sampling and 3. Whole saliva. A total of 100 adult patients will participate in this study. These subjects will be of two patient populations: 1) diseased population, with active gum disease; and 2) a low-risk disease population, with no active gum disease. Patients will be seen 6 times over the course of the study over a period of approximately 12 months. At each visit the patient will undergo oral fluid collection, as previously described, and thorough examinations of the mouth, including the taking of measurements for study purposes. Patients will also have radiographs taken at baseline, month 6, and end of study visits.

Read the detailed description

The ultimate goal of this investigation is to validate the ability of the prototype platform (miniaturized microfluidic device that can rapidly (within 15 minutes) measure small volumes of oral fluids (on the order of nanoliters of fluid) and identify biomarkers of disease such as mediators of inflammation (interleukins -1 and -6; C-reactive protein (CRP), and a marker of bone resorption (ICTP). This analysis will aid in the diagnosis of active periodontal (gum) disease as well as diseases involved in systemic inflammation (e.g., cardiovascular disease) or systemic bone loss (osteoporosis). This project will have two specific goals: 1. To validate the ability of the diagnostic to measure the designated mediators from oral fluids; and 2. Determine the ability of the multiplexed format of mediator analysis to predict disease activity (future bone loss) in patients at high and low risk for disease. This proposed feasibility study will then aid in providing the impetus for sample size and other design requirements for larger, more expanded human clinical trial testing and subsequent technology transfer.

The record says: finished, as of the sponsor's last update on 14 Dec 2015. 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?

Proof of principle study to determine ability of device to predict disease activity in patients at high and low risk for disease. (time frame: 2 years). 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 NCT00277745, which also lists 6 linked publications.

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?
