A Clinical Study to Examine the Effects of an Experimental Toothpaste Compared to a Regular Fluoride Toothpaste on Breath Odor in a Population With Gingivitis

Completed · Not applicable

Conditions studied: Halitosis

In brief

The purpose of this study is to investigate the efficacy of an experimental dentifrice, containing 0.454 percent (%) stannous fluoride and 0.3% zinc chloride, to reduce oral malodor, compared to a marketed regular fluoride dentifrice after 3 weeks twice daily brushing in a population of clinically diagnosed gingivitis.

You may qualify if…

Provision of a signed and dated informed consent document indicating that the participant has been informed of all pertinent aspects of the study before any assessment is performed.
Participant who is willing and able to comply with scheduled visits, product usage requirements, study procedures and lifestyle restrictions.
Participant in good general and mental health with, in the opinion of the investigator or medically qualified designee, no clinically significant or relevant abnormalities in medical history (for example, a medical condition or medication confirmed to contribute to xerostomia),or upon oral examination, that would impact the participant's safety, wellbeing or the outcomes of the study, if they were to participate in the study, or affect the participant's ability to understand and follow study procedures and requirements.
Participant with generally good oral health that fulfil all of the following:
Having at least 20 natural (vital) teeth.
Good oral health without lesions in the oral cavity (including the tongue) that could interfere with the study evaluations.
Having clinically diagnosed, plaque-induced gingivitis defined as having 10-30% bleeding sites from the bleeding on probing assessment.
At Screening (Visit 1) and prior to brushing with assigned dentifrice at Baseline (Visit 2) participants must provide 2 samples of mouth air, which must have a mean hydrogen sulfide concentration greater than 150ppb. There must be less than or equal to (<=)500ppb difference between the values measured at screening and baseline (pre-brushing).
At Baseline (Visit 2), prior to brushing with assigned dentifrice participants must provide a breath sample with a mean organoleptic score greater than or equal to (>=)2.

You may not qualify if…

Participant who has participated in other studies (including non-medicinal studies) involving investigational product(s) within 30 days of study entry and/or during study participation or who has previously been enrolled in this study.
Participant with, in the opinion of the investigator or medically qualified designee, an acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study product administration or may interfere with the interpretation of study results and, in the judgment of the investigator or medically qualified designee, would make the participant inappropriate for entry into this study.

General medical exclusions:
Participant with a medical history that may prevent the Participant from participating in the study until study conclusion.

Participant with a significant infectious disease, such as hepatitis, COVID-19, flu, respiratory infection, tuberculosis, or any other condition which can be transmitted in saliva or salivary aerosols which, in the opinion of the examiner, could endanger the organoleptic assessors.
Participant with any condition that impacts gum health (for example, Type 2 Diabetes).
General medication exclusions:
Participant using any antibiotic medication within 14 days prior to screening or at any time during the study.
Participant using chlorhexidine, cetylpyridinium chloride (CPC) or stannous fluoride containing mouthwash or dentifrice within 14 days prior to Visit 2 or between Visit 2 and 3.
Participant taking medications which may impact oral mouth odor (for example, Diazepam, Alprazolam, Lorazepam and so on).
General oral exclusions:
Participant with orthodontic or prosthetic appliances (fixed or removable), including dental implants.
Participant having had professional dental cleaning (oral prophylaxis) within 3 months prior to the screening visit or at any time during the study.
