About this study

Official title: Adjunctive Effect of Erythritol on Pocket Closure Rates: RCT

This clinical trial is studying whether using erythritol powder during non-surgical periodontal treatment (deep cleaning) helps improve gum health in people with severe periodontitis. Participants with deep gum pockets (4 mm or more) receive standard treatment alone or standard treatment plus cleaning with erythritol powder. The goal is to evaluate if adding erythritol improves outcomes such as healing of gum pockets, bleeding, plaque levels, and gum attachment compared to standard treatment alone.

Read the detailed description

This study is testing whether erythritol powder, used during non-surgical periodontal treatment (also known as deep cleaning), can help improve gum health in people with advanced periodontitis (stage 3 or 4). Periodontitis is a serious gum infection that damages the soft tissue and bone supporting the teeth. Standard treatment includes removing plaque and tartar using manual tools or ultrasonic devices.

In this study, gum pockets that are 4 mm deep or more are treated either with standard care alone or with standard care plus a cleaning method that uses air pressure and erythritol powder (a sugar alcohol with antibacterial properties). The goal is to determine whether this additional step leads to improved clinical outcomes.

Participants are randomly assigned to one of the two treatments. The study tracks improvements in gum pocket depth after 2 and 4 months, as well as other indicators of periodontal health like bleeding and plaque levels. Researchers are also evaluating whether factors such as age, sex, smoking status, or diabetes influence treatment response.

Being tested
Non-surgical periodontal therapy + sub-gingival air polishing, Non-surgical periodontal therapy alone
Medical subject headings
Periodontitis, Periodontal Pocket, Gingival Pocket

What participants receive

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

  • Non-surgical periodontal therapy + sub-gingival air polishingProcedure or surgery

    Participants receive a single session of non-surgical periodontal therapy (NSPT) using ultrasonic and manual instruments, combined with sub-gingival air polishing using erythritol powder. The treatment is applied to periodontal pockets with probing depth ≥ 4 mm in non-adjacent teeth.

  • Non-surgical periodontal therapy aloneProcedure or surgery

    Participants receive a single session of non-surgical periodontal therapy (NSPT) using ultrasonic and manual instruments.

Study groups in NCT06958874
Study groupRoleWhat they receive
NSPT (Control)Active comparatorParticipants receive standard non-surgical periodontal treatment (scaling and root planing) using ultrasonic and manual instruments in selected periodontal pockets.
Receives: Procedure: Non-surgical periodontal therapy alone
NSPT + ERY (Test)ExperimentalParticipants receive standard non-surgical periodontal treatment combined with sub-gingival air polishing using erythritol powder in selected periodontal pockets.
Receives: Procedure: Non-surgical periodontal therapy + sub-gingival air polishing

What is being measured

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

  1. Proportion of periodontal pockets with successful pocket closure

    Percentage of treated periodontal pockets (with baseline probing depth ≥ 4 mm) that reach pocket closure, defined as probing pocket depth ≤ 4 mm without bleeding on probing, or ≤ 3 mm, at follow-up.

    Measured: 2 months and 4 months after treatment

Questions about this trial

What is this clinical trial studying?

A study testing Non-surgical periodontal therapy + sub-gingival air polishing and Non-surgical periodontal therapy alone in people with Periodontitis and Pocket, Periodontal, run by University of L'Aquila at 1 site in Italy.

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 5 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 6 May 2025. 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 Italy. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of periodontal pockets with successful pocket closure (time frame: 2 months and 4 months after treatment). 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 May 2025.
