Evaluation and comparison of Gingival Bleeding (as assessed by number of bleeding sites) following twice daily use of a sodium bicarbonate experimental dentifrice compared to a 0% sodium bicarbonate experimental dentifrice toothpaste after 24 weeks. 24 weeks [clinicaltrials_resource:87766c4d0e39bffaedf45b5682e26166]

The Bleeding Index will be performed by a single examiner using a color coded periodontal probe. The probe will be engaged approximately 1 millimetre (mm) into the gingival crevice. A moderate pressure will be used whilst sweeping from interproximal to interproximal along the sulcular epithelium. The BI scoring system to be used is as follows: 0= No bleeding after 30 seconds; 1= Bleeding upon probing after 30 seconds; 2= Immediate bleeding observed
