Abstinence or vasectomies are acceptable if the female subject agrees to implement an acceptable form of birth control if her lifestyle/partner changes;

- •Are free of any systemic or dermatologic disorder, which, in the opinion of the Principal Investigator (PI), will interfere with the study results or increase the risk of adverse events (AEs); and
- •Read, understand, and provide signed informed consent.

- •Any clinically significant central nervous system, cardiac, pulmonary, renal, gastrointestinal (GI), endocrinological, respiratory, or metabolic conditions (or history), or other pathological or physiological conditions, that might interfere with the study results in the investigator's opinion;
- •Any condition which, in the investigator's opinion, puts the subject at significant risk, could confound the study results, or may interfere significantly with the subject's participation in the study;
- •Have known or suspected allergies to oral care products, toothpaste, or ingredients in toothpaste;
- •Immunization within 10 days of Day 1;
- •Anticipated need for surgery or hospitalization during the study;

- •Donation or loss of blood (excluding volume drawn at screening) of ≥ 450 mL within 3 months of Day 1;
- •Active or lifetime infection (e.g., negative test for human immunodeficiency virus (HIV) and hepatitis, and no history of tuberculosis and syphilis) or a history of severe infection during the 30 days prior to screening;
