What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores how Intensive Periodontal Therapy, a special dental cleaning, affects oral health and overall health indicators related to heart disease and type 2 diabetes. The therapy includes regular cleanings and subgingival chlorhexidine irrigation, a germ-fighting rinse, to determine if it improves health markers in the body. Suitable candidates for this trial have moderate to severe gum disease, at least 16 teeth, and are managing conditions like type 2 diabetes or heart disease. As a Phase 4 trial, the treatment is already FDA-approved and proven effective, allowing researchers to understand its benefits for more patients.

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

What is the safety track record for these treatments?

A previous study found non-surgical gum treatment to be safe and easy to handle. It improves oral health and reduces related health issues. This treatment has been used for a long time and is a common method to enhance gum health.

Research shows that rinsing under the gums with chlorhexidine effectively reduces gum swelling and plaque. Studies indicate it is generally safe in dental care, helping control gum disease without major side effects.

Both treatments are widely used and have a good safety record. They are integral to regular dental practices aimed at improving oral health. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about this trial because it explores the potential systemic health benefits of advanced periodontal care. Unlike traditional periodontal treatments which typically focus on scaling and root planing (SRP) alone, this approach includes subgingival chlorhexidine irrigation, which targets bacteria below the gum line more effectively. Additionally, it combines behavioral advice from dental professionals to boost patient motivation and oral health maintenance. This comprehensive method could not only improve oral health but also have positive effects on overall health, like reducing inflammation and improving cardiovascular markers.

What evidence suggests that this trial's treatments could be effective for improving oral health and systemic conditions?

Research has shown that non-surgical treatments for gum disease, such as scaling and root planing, effectively improve oral health. These treatments reduce gum swelling and control plaque, which are crucial for managing gum disease. For individuals with other health issues, like heart disease or diabetes, this treatment has also been linked to better overall health.

In this trial, participants in the Treatment Group will receive subgingival chlorhexidine irrigation, which involves rinsing under the gums with a germ-killing liquid, in addition to standard periodontal treatment. Studies indicate that this method can significantly decrease gum bleeding and swelling. Combining both treatments shows promise for improving oral health and may also benefit overall health. ^{1 2 6 7 8}

Trial Overview

The study tests if Intensive Periodontal Therapy (deep cleaning of teeth) improves oral health and affects systemic health biomarkers. It involves around 200 participants split into a Treatment Group receiving therapy and a Control Group, using professional dental care teams.

How Is the Trial Designed?

Group I: Treatment Group Experimental Treatment 3 Interventions

The Treatment Group will receive the same periodontal treatment in addition to having subgingival chlorhexidine irrigation. All subjects will also complete a set of questionnaires (PANAS \& PMT) using an online form. A subset of 50 subjects from each group will be randomly selected to have oral images captured using an intra-oral scanner at Baseline and a subset of follow-up visits. Additionally, subjects in the Treatment Group will also receive brief behavioral advice from dental professionals focusing mainly on motivation and acknowledgement.

Group II: Control Group Active Control 1 Intervention

The Control Group will receive an initial periodontal treatment consisting of a pre-procedural rinse and scaling \& root planning (SRP). Subjects in the Control Group will receive no products during the course of the study. They will receive a commercial connected toothbrush, toothpaste, mouthwash, proxabrush, and floss at the end of the study. Subjects will be scheduled to receive flow mediated dilation (FMD) and carotid intima media thickness (IMT) measurements prior to Baseline and approximately 4 weeks after their Baseline visit.
