Study Summary
The Purpose of This Research Study is to Compare the Effectiveness of a Non-fluoride Whitening Toothpaste (Test) to That of a Non-whitening Fluoride Toothpaste (Negative Control) in Improving Tooth Whiteness (Removal of Extrinsic Stains) Over 8 Weeks of Unsupervised Use.
Primary Outcome
The Modified Lobene Stain Index (MLSI) Area x Intensity score for the overall tooth surfaces will be used for measurment of tooth color. The Primary Endpoint is the MLSI (extrinsic stain mean scores) at the 8-week timepoint compared to baseline. The between treatments would also be a primary endpoint after 8 weeks of unsupervised use.
