About this study

Official title: Photodynamic Disinfection in Combination With Scaling and Root Planing in the Treatment of Chronic Periodontitis

This study is to determine whether scaling and root planing (SRP) followed by photodynamic disinfection results in improved outcomes that persist over time in adults with chronic periodontitis when compared with subjects with SRP alone.

Read the detailed description

Extensive research has shown that lethal photosensitization with low levels of laser light is an effective method of killing numerous types of organisms. This therapy avoids the use of antibiotics along with their potential side effects. The initial application of this therapy to the oral cavity is particularly appropriate since the therapy can be applied topically either in a specific or general fashion, killing is immediate and resistance is unlikely as it is free radical-mediated. In addition, the disease states being treated (gingivitis \& periodontitis) are highly prevalent and associated with significant morbidity. The equipment and costs of this therapy are simple, easily applied and relatively inexpensive compared with current therapies. Based on the scientific data to date this therapy has the potential of significantly improving the oral health of those affected.

This is a pivotal, prospective, randomized, examiner blinded, multicenter study to evaluate the effect of a single treatment of photodynamic disinfection in adults with chronic periodontal disease.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing PerioWave and Scaling and Root Planing in people with Periodontitis, run by Ondine Research Laboratories at 4 sites in Canada.

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 8 inclusion and 12 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 21 May 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Canada. 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 phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Increase in clinical attachment level (time frame: 6, 12 weeks). 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 NCT00297531, which also lists 45 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2007; AzTrials last refreshed its copy on 7 Nov 2026.
