Label	Type	Description	Intervention Names
Brush / Espresso Mild Prototype	Experimental	All subjects will receive a marketed fluoride-containing dentifrice and a soft flat trimmed bristled toothbrush to use for the one week wash out period and throughout the study. Subjects will be required to record their daily product use times on a subject diary. After the one week wash out period, subjects subjects will use their assigned mouthwash for the first time at the site under supervision. Subjects will brush their teeth at the site after all assessments are complete. That evening, subjects will brush their teeth and rinse a second time unsupervised. All other twice daily brushing/rinsing will occur unsupervised at home. Subjects will be required to record their daily product use times (brushing and rinsing) on their subject diary.	Other: Brush / Espresso Mild Prototype
Brush / Espresso Intense Prototype	Experimental	All subjects will receive a marketed fluoride-containing dentifrice and a soft flat trimmed bristled toothbrush to use for the one week wash out period and throughout the study. Subjects will be required to record their daily product use times on a subject diary. After the one week wash out period, subjects subjects will use their assigned mouthwash for the first time at the site under supervision.

Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Mean malodor intensity assessed at 60 minutes after product use	Mean malodor intensity will be independently assessed by three odor trained judges 60 minutes after product use on Day 0 using the following scale: 0 = No appreciable odor, 1 = Barely noticeable odor, 2 = Slight but clearly noticeable odor, 3 = Moderate odor, 4 = Strong odor, 5 = Extremely foul odor	After 60 minutes of product use
Mean malodor intensity assessed at 120 minutes after product use	Mean malodor intensity will be independently assessed by three odor trained judges 120 minutes after product use on Day 0 using the following scale: 0 = No appreciable odor, 1 = Barely noticeable odor, 2 = Slight but clearly noticeable odor, 3 = Moderate odor, 4 = Strong odor, 5 = Extremely foul odor	After 120 minutes of product use
Mean malodor intensity assessed at 180 minutes after product use	Mean malodor intensity will be independently assessed by three odor trained judges 180 minutes after product use on Day 0 using the following scale: 0 = No appreciable odor, 1 = Barely noticeable odor, 2 = Slight but clearly noticeable odor, 3 = Moderate odor, 4 = Strong odor, 5 = Extremely foul odor	After 180 minutes of product use
Mean malodor intensity assessed at 240 minutes after product use	Mean malodor intensity will be independently assessed by three odor trained judges 240 minutes after product use on Day 0 using the following scale: 0 = No appreciable odor, 1 = Barely noticeable odor, 2 = Slight but clearly noticeable odor, 3 = Moderate odor, 4 = Strong odor, 5 = Extremely foul odor	After 240 minutes of product use
Mean malodor intensity assessed at 12 hours after product use on Day 7	Mean malodor intensity will be independently assessed by three odor trained judges 12 hours after product use on Day 7 using the following scale: 0 = No appreciable odor, 1 = Barely noticeable odor, 2 = Slight but clearly noticeable odor, 3 = Moderate odor, 4 = Strong odor, 5 = Extremely foul odor

Secondary Outcomes

Measure	Description	Time Frame
Total volatile sulfur compounds (VSC) concentration assessed at 60 minutes after product use on Day 0	Two mouth air sample will be evaluated 60 minutes after product use on Day 0 using the Oral Chroma Halitosis Measuring instrument, a portable gas chromatograph with a highly sensitive semiconductor gas detector that will determine the total VSC concentration in breath (hydrogen sulfide, methyl mercaptan, and methyl sulfide) in the range of 50- 2400ppb.

Eligibility Module

Eligibility Criteria

Inclusion Criteria:

Able to comprehend and follow the requirements and restrictions of the clinical trial (including willingness to use the assigned study products per instructions, availability on scheduled visit dates and likeliness of completing the clinical trial) based upon research site personnel's assessment;
Evidence of a personally signed and dated informed consent document indicating the subject (or legally acceptable representative) has been informed of all pertinent aspects of the trial;
Able to read and understand the local language (subject is capable of reading the documents);
Adequate oral hygiene (i.e., brush teeth daily and exhibit no signs of oral neglect);
Adults, 18 years of age and older, in good general and oral health without any known allergy to commercial dental products or cosmetics;

- For females: Postmenopausal state (i.e. at least 1 year without menses without an alternative medical condition prior to the first study IP administration) or premenopausal/perimenopausal state with an effective means of contraception.
- For males: No pregnant or lactating spouse or partner at screening and willingness to utilize an acceptable form of birth control with spouse or any potential partner during the study and for 30 days thereafter.
Females of childbearing potential must be using a medically acceptable method of birth control for at least one month prior to Visit 1 and agree to continue using this method during their participation in the clinical trial. Medically acceptable forms of birth control that may be used by the subject and/or his/her partner include:

- Abstinence
A minimum of 16 uncrowned teeth;
At Screening (Visit 1) and before brushing with the assigned study product at Baseline (Visit 2), subjects must provide 2 samples of mouth air, which must have a mean hydrogen sulfide concentration greater than 200ppb. At screening and baseline (pre-brushing), the two samples of mouth air must have a ≤ 500ppb difference in hydrogen sulfide values;
At Baseline (Visit 2), before brushing with assigned dentifrice, subjects must provide a breath sample with a mean organoleptic score ≥3.5 across judges;
Absence of significant oral soft tissue pathology, periodontitis and active dental caries, based on a visual examination and at the discretion of the Investigator; and

Exclusion Criteria:

Diagnosed with Xerostomia;

Has a compromised immune system;
Has any acute or chronic, medical or psychiatric conditions) 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 judgement of the medically qualified investigator, would make the subject inappropriate for entry in this study;
