Phase 4

Completed

• Conditions: Healthy
• Interventions: Other: Colgate Cavity Protection Toothpaste; Other: Listerine Advanced Gum Alcohol; Other: LISTERINE Cool Mint Antiseptic Mouthwash; Other: Listerine Advanced Gum Zero; Other: LISTERINE ULTRACLEAN Tartar Control Antiseptic Mouthwash Cool Mint

• Registration Number: NCT05645705
• Lead Sponsor: Johnson & Johnson Consumer Inc. (J&JCI)

Brief Summary

The purpose of this study is to assess the oral tissue tolerance (tissues within the mouth) for irritation caused by added ingredients in mouthwashes. This will be assessed based on oral tissue exams and adverse reactions.

• Absence of fixed or removable orthodontic appliance or removable partial dentures

Exclusion Criteria

• History of significant adverse effects, including sensitivities or suspected allergies, following use of oral hygiene products such as toothpastes, mouthwashes and red food dye
• Dental prophylaxis within four weeks prior to Baseline visit
• History of medical conditions requiring prophylactic antibiotic coverage prior to invasive dental procedures
• Use of antibiotics, anti-inflammatory or anticoagulant therapy, phenytoin sodium or diphenylhydantoin, cyclosporin A, immunostimulants/ immunomodulators during the study or within the one month prior to the Baseline exam. Intermittent use of certain anti-inflammatory medication (ibuprofen, Aspirin); oral steroids and calcium channel blockers are acceptable at the discretion of the investigator
• Use of chemotherapeutic anti-plaque/anti-gingivitis products such as triclosan, essential oils, cetylpyridinium chloride, sodium fluoride with CPC, stannous fluoride, zinc or chlorhexidine digluconate containing mouthwashes and toothpastes within the four weeks prior to the Baseline exam
• Known allergy or sensitivity or history of significant adverse effects to any of the investigational product and/or product ingredients (or other ingredients in the products)
• Self-reported pregnancy or lactation (this criterion is due to oral tissue changes related to pregnancy and nursing which can affect interpretation of study results)
• Self-reported smokeless tobacco user including snuff, chewing tobacco, vaping and e-cigarette usage
• Males with a pregnant partner or a partner who is currently trying to become pregnant
• Suspected alcohol or substance abuse (examples, amphetamines, benzodiazepines, cocaine, marijuana, opiates)
• Significant medical or oral condition which may interfere with a participant's participation in the study, including cancer, chronic kidney disease, chronic obstructive pulmonary disease (COPD), immunocompromised state (weakened immune system) from solid organ transplant, serious heart conditions, (such as heart failure, coronary artery disease, or cardiomyopathies) Sickle cell disease, Type 2 diabetes mellitus at the discretion of the Investigator
• Participation in any clinical trial within 30 days of Screening visit
• Diagnosed Temporo-mandibular joint dysfunction/disorder
• Participants who wear bruxing devices, dental aligners, retainers
• Participants who were previously screened and ineligible or were randomized to receive investigational product
• Participants who are related to those persons involved directly or indirectly with the conduct of this study (that is, principal investigator, sub-investigators, study coordinators, other site personnel, employees of Johnson & Johnson subsidiaries, contractors of Johnson & Johnson, and the families of each)
• Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the participant inappropriate for entry into this study
• COVID-19 restrictions: participants who fail to meet the criteria of the site's screening consent for Preventing Infection in the site's COVID-19 consent form

Primary Outcome Measures

Name	Time	Method
Change from Baseline in Oral Tolerance Based on Oral Hard and Soft Tissue Exams	Baseline up to Day 14	Change from baseline in oral tolerance based on oral had and soft tissue exams will be reported. Oral examination will be conducted to monitor oral soft and hard tissues tolerance to the treatments. Buccal and sublingual mucosae, lips/labial mucosa, mucobuccal fold, gingiva, tongue, hard and soft palate, uvula, oropharynx, teeth and dental restorations will be examined and findings will be recorded in the electronic data capture (EDC) system.
Number of Participants with Adverse Events (AEs)	Up to Day 14	An AE is any untoward medical occurrence in a clinical study participant temporally associated with the clinical investigation, whether or not the event has a causal relationship to the participant's participation in the trial.

Secondary Outcome Measures

Name	Time	Method
Salivary Flow Rate	Baseline and immediately (0), 2, 5, 10, 15 and 30 minutes after intervention use	Saliva samples will be collected by participants at baseline and then immediately (0), 2, 5, 10, 15 and 30 minute timepoints after intervention. The final amount of saliva will be weighed to calculate the milliliter per minute (mL/min). The saliva flow rate will be expressed as mL/min.
Saliva Potential of Hydrogen (pH)	Baseline and 2, 5, 10, 15 and 30 minutes after intervention use	The pH value of saliva will be measured by placing the saliva sample onto the pH-sensitive electrode.
