About this study
Official title: Clinical Evaluation of a Stannous Fluoride Toothpaste Versus a 67% Bicarbonate Toothpaste and Colgate Cavity Protection Toothpaste for Dental Plaque Reduction and Prevention of Gum Problems: a Six-month Clinical Study in Italy
Qualified subjects will be enrolled and randomized to either one of the three study groups described above based on their initial modified gingivitis and plaque scores. Subjects will be instructed to use the products according to the instructions provided. Subjects will return to the dental office for evaluation after three months and six months of product use. All subjects will be followed for adverse events throughout the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Lobene Modified Gingivitis Assessment
Modified Gingivitis Index score from 0 to 4 will be assigned by the examining dentist to all tooth surfaces using a dental light and dental mirror. A whole mouth mean score for each subject will be determined by adding the values given by the examining dentist to each scoreable surface and dividing that number by the total number of surfaces scored
Measured: Baseline, 3 month, 6 month
Saxton Gingival Bleeding Assessment
Gingival bleeding is assessed 30 seconds after probing; a score of 0 represents an absence of bleeding, a score of 1 is given if bleeding is observed within 30 seconds after probing and a score of 2 is given if bleeding is observed immediately on probing
Measured: Baseline, 3 month, 6 month
Modified Quigley-Hein Plaque Index
First using a red dye solution to disclose the plaque, a Modified Quigley-Hein Plaque Index score of 0 to 5 will be assigned to all scoreable disclosed tooth surfaces using a dental light and dental mirror. A whole mouth score for each subject will be determined by adding the values given by the dental examiner to each scoreable surface and dividing that number by the total number of surfaces scored.
Measured: Baseline, 3 month, 6 month
