| Main Objective: To evaluate and compare gingivitis as measured by Modified Gingival Index (MGI) and Bleeding Index (BI) following twice daily use of an experimental toothpaste compared to a reference toothpaste after 12 weeks;Secondary Objective: To evaluate and compare gingivitis as measured by MGI and BI following twice daily use of experimental toothpaste compared to reference toothpaste after 4 and 8 weeks. To evaluate and compare dental plaque scores (overall and interproximal) following twice daily use of experimental toothpaste compared to reference toothpaste after 4, 8 and 12 weeks. To evaluate and compare changes in cultivable plaque bacterial groups in plaque samples, following twice daily use of experimental toothpaste compared to reference toothpaste after 4 and 12 weeks ;Primary end point(s): Modified Gingival Index | — |
