About this study
Official title: Determination of the Oral Irritation and Sensitization Potential of Two Experimental Potassium Oxalate Containing Mouthrinses
This study is 25 days long. People participating in this study will be asked to brush their teeth two times a day. People will be assigned to a mouthwash and will rinse four times a day at the site for five days. A dentist or dental hygienist will look at the mouth, teeth, tongue and gums to make sure the mouthwash does not irritate the mouth. After Day 5 of the study, people will continue to brush two times a day and will return on Day 24 to have their mouth looked at again. People without irritation in their mouth will rinse 4 times a day at the clinical site. People will return to the clinical site the next day and have a final oral exam in which the dentist or dental hygienist will look at the mouth for irritation.
Read the detailed description
This is a randomized, observer-blind, single-center, supervised, controlled, parallel-designed study. Approximately 90 generally healthy adults meeting the necessary inclusion/exclusion criteria will be enrolled so that 78 subjects (26 per treatment group) would reasonably be expected to complete the study. Subjects will have their oral soft/hard tissues assessed at Screening (visit 1), Baseline (visit 2), and Days 3, 5, 24, and 25 (visits 4,6-8). During the first week of the study, subjects will be instructed to brush their teeth for one minute in their usual manner, twice daily using the provided standard fluoride toothpaste. Subjects will return for the Baseline exam and, upon qualification with entry criteria, will be assigned to one of three treatment groups. Qualified subjects will be instructed to return to the site for five consecutive days. Subjects will have four supervised rinses with their assigned mouth rinse for either 30 or 60 seconds using 10 ml or 20 ml, at subsequent one-hour intervals. During the 5 consecutive days of exposure to the assigned mouthrinse, subjects will brush their teeth using the provided fluoride-free toothpaste and soft-bristled toothbrush.
Subjects will then have an 18-day rest period (off treatment). During this time, subjects will follow their usual oral hygiene and dietary habits, using the standard fluoride toothpaste and soft toothbrush provided, and must refrain from using any unassigned oral care products. On the 19th day after completion of Day 5 (Day 24), subjects will return for an oral examination. If no pathology is present, subjects will be given a challenge treatment (four supervised rinses) and the final oral examination will be performed on Day 25.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study is 25 days long. People participating in this study will be asked to brush their teeth two times a day. People will be assigned to a mouthwash and will rinse four times a day at the site for five days. A dentist or dental hygienist will look at the mouth, teeth, tongue and gums to make sure the mouthwash does not irritate the mouth. After Day 5 of the study, people will continue to brush two times a day and will return on Day 24 to have their mouth looked at again. People without irritation in their mouth will rinse 4 times a day at the clinical site. People will return to the clinical site the next day and have a final oral exam in which the dentist or dental hygienist will look at the mouth for irritation.
Detailed description
This is a randomized, observer-blind, single-center, supervised, controlled, parallel-designed study. Approximately 90 generally healthy adults meeting the necessary inclusion/exclusion criteria will be enrolled so that 78 subjects (26 per treatment group) would reasonably be expected to complete the study. Subjects will have their oral soft/hard tissues assessed at Screening (visit 1), Baseline (visit 2), and Days 3, 5, 24, and 25 (visits 4,6-8). During the first week of the study, subjects will be instructed to brush their teeth for one minute in their usual manner, twice daily using the provided standard fluoride toothpaste. Subjects will return for the Baseline exam and, upon qualification with entry criteria, will be assigned to one of three treatment groups. Qualified subjects will be instructed to return to the site for five consecutive days. Subjects will have four supervised rinses with their assigned mouth rinse for either 30 or 60 seconds using 10 ml or 20 ml, at subsequent one-hour intervals. During the 5 consecutive days of exposure to the assigned mouthrinse, subjects will brush their teeth using the provided fluoride-free toothpaste and soft-bristled toothbrush.
Subjects will then have an 18-day rest period (off treatment). During this time, subjects will follow their usual oral hygiene and dietary habits, using the standard fluoride toothpaste and soft toothbrush provided, and must refrain from using any unassigned oral care products. On the 19th day after completion of Day 5 (Day 24), subjects will return for an oral examination. If no pathology is present, subjects will be given a challenge treatment (four supervised rinses) and the final oral examination will be performed on Day 25.

- Willingness to use the assigned products according to instructions, availability for appointments, and likelihood of completing the clinical trial.
- Willingness to refrain from using any breath freshener products (e.g., oral care strips, candy-type mints, sprays, chewing gums, throat lozenges, cough drops or mouthwashes), whitening products and smokeless tobacco products within one week prior to and for the duration of the study, in order to reduce alternate sources of potential irritation and sensitization.
- A minimum of 20 natural teeth.
Key exclusion criteria (11 listed)
- Volunteers who report history or presence of kidney disorders or kidney stones, Crohn's Disease or other malabsorption syndromes.
- History of significant adverse effects following use of oral hygiene products such as toothpastes and mouthwashes.
- Physical limitations or restrictions that might preclude use of normal oral hygiene procedures (i.e., toothbrushing, mouthrinsing, etc.).
- History or current evidence of significant oral soft tissue pathology, excluding gingivitis, based on the dentist's visual examination and at the discretion of the investigator.
- Those requiring antibiotic premedication prior to dental treatment.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.
