Impact of an Arginine-containing Toothpaste on the Subgingival Microbiota in Patients in Supportive Periodontal Care
This study aims to see how a toothpaste with arginine affects bacteria below the gum line compared to a regular fluoride toothpaste. It focuses on people with gum disease who are already getting ongoing dental care.
The main questions it aims to answer are:
- How does an arginine toothpaste affect the bacteria below the gumline?
- How does a fluoride toothpaste affect the bacteria below the gumline?
Participants will:
- Use fluoride toothpaste or arginine toothpaste twice daily for 6 months
- After receiving the toothpaste at the baseline visit, subjects will visit the clinic at 3 months and 6 months for additional data collection.

- No Grade 3 Tooth Mobility
- Treated stage II or III periodontitis patients, whose active treatment has finalized more than 6 months before. Stage II - Interdental clinical attachment level (CAL) at the site of greatest loss equal to 3 to 4 millimeters with maximum probing depth of less than or equal to 5 millimeters. Stage III - Interdental CAL at the site of greatest loss greater than equal to 5 millimeters, probing depth (PD) greater than or equal to 6 millimeters, and radiographic vertical bone loss
- Enrolled in a periodontal maintenance treatment program
- No orthodontic banding (no permanent retainers, no orthodontic appliances (i.e., no removable plastic/metal retainer) or removable prosthesis (no removable partial and/or full denture).
- Subjects willing to participate and comply with the requirements of the study.
- Subjects that brush their teeth regularly (once or twice daily).
- Able to travel to and attend 4 research study visits over the span of the next 6 months.
- Able to independently provide consent for oneself.
- Fluent in reading, comprehending, and speaking English without assistance from a translator.
- If a patient is using prevident, they must be willing to stop using it.
Exclusion Criteria:
- Untreated or uncontrolled periodontitis or advanced (advanced periodontal disease (purulent exudate, tooth mobility, and/or extensive alveolar bone loss)
- Antibiotics intake within the previous month.
- Pregnant women and/or breastfeeding women
- Any adverse medical history (controlled and uncontrolled diabetes, osteoporosis, immunosuppression…) or long-term medication (chemotherapy and immunosuppression treatment; pharmacological treatment associated with gingival overgrowth such as the use of phenytoin, phenobarbital, lamotrigine, vigabatrin, ethosuximide, topiramate, primidone, nifedipine, amlodipine, verapamil, cyclosporine) influencing gingival conditions.
- Conditions which require antibiotic prophylaxis (infectious endocarditis, cardiac valve prosthesis…).
- Not willing to comply with the study protocol recommendation and visit schedule.
- Current smokers or those using tobacco or vaping products.
- Five (5) or more decayed, untreated dental sites (cavities) and/or any dental condition requiring urgent dental care
- Currently participating in another clinical research study now and/or within the past month.
- Has a history of allergies to oral care or personal care consumer products or their ingredients
- Has an existing medical condition that prohibits eating or drinking for periods up to 4 hours.
Any ongoing medical condition that makes a subject unsuitable for enrollment-or any new diagnosis that arises during the study that makes the subject unsuitable to continue-may lead to exclusion, as determined by the Principal Investigator on a case by case basis. Conditions that may result in exclusion include, but are not limited to:
- Recent myocardial infarction
- Recent cerebrovascular accident
- Recent placement of a cardiac valvular prosthesis
- Severe liver dysfunction
- Known or suspected current malignancy
- New antibiotic use
- Note: The Principal Investigator will review all available information about the subject and make decisions regarding both enrollment and/or continued participation.
