About this study

Official title: Approaches to Pocket/Root Debridement for Periodontal Infection Control - a Study on Effectiveness.

Treatment directed towards the control of periodontal infections is to about 90% non-surgical procedures. There is evidence from a large number of randomized controlled studies that the efficacy in terms of clinical outcomes of a full-mouth ultrasonic debridement approach (FMUD) is comparable to that of traditional section-wise scaling and root planing (SRP). A hypothesis for the current effectiveness study is that comparable clinical effects will be obtained with the FMUD approach as with conventional section-wise SRP, but with significantly more favourable patient-centred and health-economic outcomes.

This randomized study involves about 100 professionals (dental hygienists) and more than 850 patients at 40 dental clinics in the Vastra Gotaland Region, Sweden. The project not only evaluate treatment effects in terms of pertinent clinical outcomes, it also has a strong focus on patient-centered measures - patient-reported experience measures (PREM) and patient-reported outcome measures (PROM) - as well as health-economics.

Read the detailed description

All patients with chronic periodontitis (age 30 years and older) attending the selected Public Dental clinics in VG are eligible. The patients should have at least 8 teeth with pathological pockets (probing pocket depth ≥5 mm and bleeding on probing). Only patients providing signed informed consent are included.

Reported data in the study by Wennström et al. (J Clin Periodontol 2005) were used for power calculation. Thus, a total sample of 834 patients will provide a power of 95% at a significance level of p<0.05 to detect a difference of 5% in proportion of sites with "pocket closure" i.e. PPD ≤4 mm and BoP negative (primary efficacy variable) between treatment groups. For a power of 80% a total sample of 506 patients is required.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Full-mouth ultrasonic debridementProcedure or surgery

    Motivation and instruction in proper oral hygiene. Before initiation of the subgingival debridement the patient must show sufficient self-performed infection control (full-mouth plaque score <30%). One session of full-mouth ultrasonic pocket/root debridement using a piezoceramic ultrasonic instrument.

  • Section-wise scaling and root planingProcedure or surgery

    Conventional treatment approach comprising motivation, oral hygiene instructions and section-wise scaling and root planing at required number of consecutive appointments with 1-2 week interval.

One session of full-mouth ultrasonic pocket/root debridement using a piezoceramic ultrasonic instrument. A follow-up visit after 2-4 weeks is scheduled for oral hygiene control and re-motivation/re-instruction if indicated. At 3 and 6 months re-evaluation is performed and re-instrumentation of all sites showing a remaining probing pocket depth of ≥5 mm carried out. Final evaluation at 18 months.

Questions about this trial

What is this clinical trial studying?

A study testing Full-mouth ultrasonic debridement and Section-wise scaling and root planing in people with Chronic Periodontitis, run by Göteborg University at 1 site in Sweden.

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 2 inclusion and 2 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 29 Jan 2020. 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 Sweden. 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?

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?

"Periodontal pocket closure" (time frame: Up to 18 months). 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 NCT02168621, which also lists 2 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 29 Jan 2020.
