About this study

Systemically healthy periodontitis patients were recruited in this single-blind, split-mouth, randomized controlled clinical trial. After SRP, PDT was applied at probing depth (PD) ≥ 4 mm at test quadrant. At baseline, 3rd month and 6th month, clinical parameters and cytokine pattern in gingival crevicular fluids (GCFs) were analysed.

Read the detailed description

Periodontal parameters and cytokine IL-1β, IL-6, IL-8, TNF-α, MMP-8 levels were analysed.

  • SRP and Fotosan 630Device

    Also called Fotosan 630, CMS Dental, Copenhagen, Denmark

    After isolating the test quadrants with cotton roll, toluidine blue was applied into the deep pockets (PD ≥ 4mm) at the test quadrants for 10 seconds, followed by inserting a perio tip (15 or 21 mm depending on the depth of the pocket) that connected to a LED emitting device, and light was emitted for 20 seconds. Toluidine blue in the deep pocket was removed by injecting normal saline into the pocket.

Questions about this trial

What is this clinical trial studying?

A study testing SRP and Fotosan 630 in people with Periodontitis, Adult and Periodontal Pocket, run by National University of Singapore.

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 6 inclusion and 3 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 5 Mar 2018. 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?

Changes from baseline probing depth at 3rd month and 6th month (time frame: 3 months and 6 months). The study lists 9 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 5 Mar 2018.
