A Pilot Study to Test the Efficacy of a Commercial Toothpaste (Cosmetic Product)

Not applicable Interventional Periotrap Pharmaceuticals GmbH · NCT07397312

This test will see if brushing twice daily with a commercial toothpaste that contains a new ingredient helps people with periodontitis protect their oral microbiome between regular cleanings.

What this trial studies

This multicenter, controlled pilot enrolls people with periodontitis who receive professional tooth cleaning every 3–6 months and whose dental biofilm contains Porphyromonas gingivalis. Participants with at least 16 natural teeth will be assigned to use the allocated commercial dentifrice, which contains standard ingredients like fluoride plus a novel compound, and will brush twice daily for three months. The study compares oral hygiene using the test dentifrice during the non-treatment interval between two recalls, with clinical periodontal measures and microbiome-related outcomes recorded. The goal is to determine whether the product supports a eubiotic oral microbiome and helps maintain periodontal health between professional cleanings.

Who should consider this trial

Good fit: Adults with periodontitis who have at least 16 natural teeth, receive regular professional cleanings (about once to twice yearly), and have detectable Porphyromonas gingivalis in their dental biofilm are ideal candidates.

Not a fit: People without periodontitis, those lacking P. gingivalis, individuals with fewer than 16 natural teeth, or those unable to follow twice-daily brushing or attend visits are unlikely to benefit.

Why it matters

Potential benefit: If successful, the toothpaste could help maintain a healthier oral microbiome and reduce periodontal deterioration between professional cleanings.

How similar studies have performed: While fluoride and mechanical brushing are proven for oral health, the specific novel compound in this toothpaste is relatively untested in clinical trials for modifying the oral microbiome, so direct evidence is limited.

* A participant who has a recent history (within the last year) of alcohol or other substance abuse.
* A participant who has a severe oral condition (for example, necrotizing gingivitis/periodontitis or oral or peri-oral ulceration) that could compromise study outcomes or the oral health of the participant/examiner if they participate in the study.
* A participant who has previously been enrolled in this study.

Medication exclusions at screening (Visit 1):

* A participant who is using any antibiotic medication within 3 months prior to inclusion or at any time during the study.
* A participant who is currently taking an anti-inflammatory or systemic medication (for example, immunosuppressants), which could affect plaque/gingival condition (for example, ibuprofen, aspirin, cyclosporin, phenytoin, calcium channel blockers) repeatedly for more than 3 consecutive days within study participation.

Periodontal and dental exclusions:

* A participant who has a formally untreated or not controlled periodontitis.
* A participant who has active caries that could compromise study outcomes or the oral health of the participant if they participate in the study.
* A participant who has an orthodontic appliance (bands, appliances, or fixed/ removable retainers except night guards).
* A participant who has any dental condition (for example, overcrowding) that could compromise study outcomes or the oral health of the participant if they participate in the study.
