Overview
Brief Summary
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.
Detailed Description
This will be a single center, single blind (to the examiners undertaking the oral malodor assessments), randomized (stratified by the participant's sex), controlled, two arm parallel study in volunteers with clinically diagnosed gingivitis and oral malodor. The study will evaluate the clinical efficacy of an experimental dentifrice containing 0.454% stannous fluoride and 0.3% zinc chloride to reduce oral malodor after 3 weeks of twice-daily use compared to a regular reference dentifrice. Sufficient participants will be screened to randomize approximately 106 participants to study treatment (approximately 53 per treatment group) to ensure approximately 100 evaluable participants complete the study.
Investigators
Eligibility Criteria
Inclusion Criteria
- •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.
Exclusion Criteria
- •Participant who is an employee of the investigational site, either directly involved in the conduct of the study or a member of their immediate family; or an employee of the investigational site otherwise supervised by the investigator; or an employee of the sponsor directly involved in the conduct of the study or a member of their immediate family.
- •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.
- •A Participant who is pregnant (self-reported) or intending to become pregnant during the study.
- •Participant who is breastfeeding.
- •Participant who habitually smokes, uses tobacco products or who vapes.
- •Participant with known or suspected intolerance or hypersensitivity to the study products or any of their stated ingredients (or closely related compounds).
- •Participant who is unwilling or, in the opinion of the investigator or medically qualified designee, unable to comply with the requirements and/or Lifestyle Considerations of the study.
- •Participant with a recent history (within the last year) of alcohol or other substance abuse.
- •General medical exclusions:
Outcomes
Primary Outcomes
Adjusted Mean Change From Baseline (Day 0, Pre-Brushing) to Week 3 (Pre-Brushing) in Breath Organoleptic Scores
Time Frame: Baseline (Day 0, Pre-Brushing) and Week 3 (Pre-Brushing)
An organoleptic assessment was used to evaluate the oral odor and defined as a method that measures the strength of target odor and expresses the value in terms of a score with reference to a pre-defined organoleptic scale. The assessors evaluated the oral odor and scored from 0 (lowest score) to 5 (highest score), where 0= No appreciable odor, 1= Barely noticeable odor, 2= Slight but clearly noticeable odor, 3= Moderate odor, 4= Strong odor, 5= Extremely foul odor. Lower score indicates improvement. The change from Baseline was calculated as score at Week 3 (Pre-Brushing) minus score at Baseline (Day 0, Pre-Brushing). Baseline was defined as Day 0 (Pre-Brushing). Analysis was performed using Analysis of Covariance (ANCOVA) method.
