About this study

Official title: Effects of Periodontal Therapy on Markers of Acute Phase Response (APR), Oxidative Stress: Phase II {Formerly UNC Biomedical IRB Study # DENT-2019}

This study began enrollment in 2003 with final report completed in October of 2015. This submission is being provided to acquire an NCT number.

This study was successfully executed according to protocol with full enrollment and completion of 89.7% of subjects. Subjects were enrolled into a two arm study 1) Combined therapy (scaling and root planing plus Crest products) vs. 2) delayed treatment. Subjects were followed for 6 months and a wide and extensive battery of biological samples were collected to determine the effects of treatment on the local and systemic inflammatory response.

Read the detailed description

The design for this study was a single-blinded, delayed treatment, controlled, randomized, clinical trial. A total of 106 subjects, 2 sets of 53 patients each in one of 2 arms, were enrolled. For both groups at 6 weeks, 3 months, and 6 months periodontal measures, gingival crevicular fluid, and plaque were taken using standardized techniques. Blood for serum was collected at each time point, plus at an additional 2 week visit. GCF samples were collected and analyzed for PGE2 and IL-1 to provide a mediator assessment of periodontal status.These GCF data and the clinical changes were used to assure that the therapy provided had resulted in a local therapeutic benefit. These data were primarily useful as it relates to changes in systemic levels of mediators.

Subjects were recruited from the surrounding communities by means of flyer advertisements, as well as media advertisements in weekly newspapers and on the radio. Recruitment focused on subjects between the ages of 18 and 64 years with periodontal disease.

The investigators excluded persons who have less than 20 teeth; who had any serious systemic disease including: auto-immune type disorders (i.e. systemic lupus erythematous), immunosuppression (chronic systemic c steroid use, cancer chemotherapy or HIV infection), chronic liver disease including hepatitis, or diabetes mellitus; extremely obese (BMI <40), are pregnant, or who abuse alcohol or drugs. Subjects were selected from periodontal screening examinations as having 4 or more sites with pocket depths of 5 or more mm and two or more sites with attachment loss of 3 mm or more and who required scaling and root planing.

The Phase II set of 106 patients had periodontal therapy consisting of one of two treatments:

Treatment 1: A 6-week observation period (treatment delay), then full-mouth scaling and root planing plus specific oral hygiene regimen (OHR) (Group 1);

Treatment 2: A 6-week observation period (treatment delay), then a further 6-month observation period (delayed treatment), followed by scaling and root planing plus specific oral hygiene regimen (OHR) at 6 months (Group 2).

Secondary outcomes (1)
  1. Relationship between S&RP and OHR on PGE2 & IL-1beta

    to determine the relationship between the effects of S\&RP plus OHR on levels of systemic inflammation and local changes in periodontal status, GCF levels of PGE2 and IL-1 and the periodontal microbiota, quantifying the levels of 40 organisms.

    Measured: 6 months post S&RP

Questions about this trial

What is this clinical trial studying?

A study testing Scaling and Root Planing (S&RP) in people with Periodontitis, run by University of North Carolina, Chapel Hill.

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 1 inclusion and 5 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 18 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Effects of S&RP & OHR on C-Reactive protein (time frame: 6 months post S&RP). The study lists 10 primary outcomes in all. 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 18 Dec 2017.
