Is this trial a fit for you?

Likely a good fit

Ideal candidates are patients with 3 to 8 teeth showing advanced periodontal attachment loss and specific clinical measurements indicating severe inflammation.

Probably not a fit

Patients with ongoing cancer treatments, poor oral hygiene, or other complicating dental conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to evaluate the effectiveness of a non-surgical treatment for advanced periodontal disease using a chitosan brush and chitosan gel. Patients who have not responded well to conventional treatments will receive mechanical debridement combined with the application of Labrida GeliX Chitosan gel. The primary objective is to measure the reduction in periodontal inflammation and attachment loss over a period of 6 to 12 months. The study will compare outcomes between a test group receiving the chitosan treatment and a control group.

Why it matters

Potential benefit: If successful, this treatment could significantly improve outcomes for patients with advanced periodontal disease who have not benefited from traditional therapies.

How similar studies have gone: While this approach is innovative, similar studies have shown promise in using adjunctive therapies for periodontal disease, suggesting potential for success.

* Teeth with active peri-apical pathology
* Teeth with root resorption as seen on radiographs
* Teeth with prosthodontic technical complications should be excluded or treated before inclusion (e.g., overhangs, open contacts with food impaction)
* Teeth with pockets from other reasons than periodontal disease
