What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Probing pocket depth

    distance from gingival margin to base of the clinical pocket by William's periodontal probe

    Measured: Baseline, one month, three month

Secondary outcomes (3)
  1. Clinical attachment loss

    distance in millimeter from a fix reference point (cement-enamel junction) to the bottom of probable pocket at experimental sites

    Measured: Baseline, one month, three month

  2. Bleeding upon probing

    presence or the absence of bleeding up to 30 second after probing with a William's periodontal probe

    Measured: Baseline, one month, three month

  3. plaque index

    teeth number 16,12,24,36,32,44 are evaluated according to silness plaque index instruction were scored between 0 to 3

    Measured: Baseline,before PDT procedure, one month, three month

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Adjunctive Photodynamic Therapy, Light-emitting diod Irradiation and applying Photosensitizer in people with Chronic Periodontitis, run by Tehran University of Medical Sciences at 1 site in Iran.

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 9 inclusion and 0 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: status not confirmed, as of the sponsor's last update on 6 Apr 2011. 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 Iran. 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.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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?

Probing pocket depth (time frame: Baseline, one month, three month). 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 6 Apr 2011.
