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;
  2. 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;
  3. Able to read and understand the local language (subject is capable of reading the documents);
  4. Adequate oral hygiene (i.e., brush teeth daily and exhibit no signs of oral neglect);
  5. Adults, 18 years of age and older, in good general and oral health without any known allergy to commercial dental products or cosmetics;

  6. Negative pregnancy urine tests (females of child-bearing potential only);

  7. 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:

  9. 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.

  8. Planned surgery during the trial period, 6 months prior to clinic visit 1 or 30 days after the end of study period;
  9. Has a compromised immune system;
  10. 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;

Study arms

  • Experimental
    Brush / Espresso Mild Prototype

    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.
