Is this trial a fit for you?

Likely a good fit

Adults aged 18 to 80 with active generalized periodontal disease who have at least 20 natural teeth, can give informed consent, and can attend three clinic visits are eligible.

Probably not a fit

People with only gingivitis, fewer than 20 natural teeth, other oral conditions or orthodontic appliances that interfere with assessment, pregnant or breastfeeding women, or those unable to consent are unlikely to benefit from this comparison.

What this trial studies

This single-center, randomized, intra-individual split-mouth study compares a tested interdental brush with a comparative interdental brush in adults with active generalized periodontal disease over four weeks. Each participant uses one brush type on one side of the mouth and the other brush on the opposite side, with random assignment at the inclusion visit. Three visits are scheduled: pre-inclusion screening, inclusion/randomization and start of use, and an end-of-study visit about one month later. Outcomes focus on interdental cleaning efficacy measured at baseline and at the end of the study.

Why it matters

Potential benefit: If successful, the results could identify a better interdental brush to improve interdental cleaning and reduce gum inflammation for people with periodontal disease.

How similar studies have gone: Prior research shows interdental brushes generally reduce plaque and gum bleeding compared with floss or no interdental cleaning, but direct head-to-head comparisons of specific brush designs are limited.
