iii. Currently taking a systemic medication which, in the opinion of the C. Baseline, Day 28 and Day 96 Assessment Visits i. Has taken antibiotics in the previous 14 days. ii. Has taken an anti-inflammatory medication which, in the opinion of the investigator, could affect gingival condition in the previous 14 days.

Has taken a systemic medication which, in the opinion of the investigator, could affect gingival condition in the previous 14 days (e.g. calcium channel blockers, or aspirin therapy).could affect gingival condition in the previous 14 days (e.g. calcium channel blockers, or aspirin therapy).Investigator, could affect gingival condition (e.g. calcium channel blockers, or aspirin therapy).

  • Have current active caries or periodontitis that may, in the opinion of the investigator, compromise the study or the oral health of the subjects if they participate in the study.
  • Restorations in a poor state of repair.
  • Partial dentures or orthodontic appliances.

Outcomes

Primary Outcome Measures

Number of Bleeding Sites at Week 12
Number of bleeding sites was measured as bleeding index (BI) via a single examiner using a color coded periodontal probe. The probe was engaged approximately 1 millimetre (mm) into the gingival crevice. A moderate pressure was used whilst sweeping from interproximal to interproximal along the sulcular epithelium. The BI was assessed on the facial and lingual gingival surfaces of each scorable tooth (7-7 in each arch). The BI scoring system used to measure bleeding sites is as follows: 0= No bleeding after 30 seconds; 1= Bleeding upon probing after 30 seconds; 2= Immediate bleeding observed. Bleeding sites were assessed as the number of bleeding sites with a BI score of 1 or 2.

Secondary Outcome Measures

Number of Bleeding Sites at Week 4
Number of bleeding sites was measured as BI via a single examiner using a color coded periodontal probe. The probe was engaged approximately 1 mm into the gingival crevice. A moderate pressure was used whilst sweeping from interproximal to interproximal along the sulcular epithelium. The BI was assessed on the facial and lingual gingival surfaces of each scorable tooth (7-7 in each arch). The BI scoring system used to measure bleeding sites is as follows: 0= No bleeding after 30 seconds; 1= Bleeding upon probing after 30 seconds; 2= Immediate bleeding observed. Bleeding sites were assessed as the number of bleeding sites with a BI score of 1 or 2.
Bleeding Index (BI) at Week 4 and Week 12
BI was assessed by a single examiner using a color coded periodontal probe. The probe was engaged approximately 1mm into the gingival crevice. A moderate pressure was 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
Modified Gingival Index (MGI) at Week 4 and Week 12
MGI was assessed on facial and lingual surfaces at two sites on each tooth (papillae and margin). The scoring of the MGI was performed under dental office conditions using a standard dental light for illuminating the oral cavity. This procedure was performed by a single examiner. The MGI scoring system is as follows: 0 = absence of inflammation; 1 = mild inflammation; slight change in color, little change in color; little change in texture of any portion of the marginal or papillary gingival unit; 2 = mild inflammation; criteria as above but involving the entire marginal or papillar gingival units; 3= moderate inflammation; glazing, redness, edema, and/ or hypertrophy of the marginal or papillary gingival unit; 4 = severe inflammation; marked redness, edema and/or hypertrophy of the marginal or papillary gingival unit, spontaneous bleeding, congestion, or ulceration.
Number of Participants With Visible Blood in Expectorate (Presence [Trace, Substantial]/Absence) at Week4 and Week 12
Visible blood in expectorate for each participant was classified as (i) Present (Trace or Substantial) (ii) Absent. The number of participants with blood 'Present' (Trace or Substantial) or 'absent' in expectorate was analyzed.

5. Study Description

Brief Summary
This will be a single-center, 12 week, examiner-blind, randomized, stratified (gender and baseline mean whole mouth MGI score), two-treatment, parallel group, clinical study in healthy adult volunteers with moderate gingivitis. This study will evaluate the efficacy of a dentifrice containing 0.454% weight by weight (w/w) stannous fluoride to control gingivitis and gingival bleeding following 12 weeks twice daily brushing, compared to a negative control dentifrice.
