Details and patient eligibility

About

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.

Enrollment: 253 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

ii. Currently taking an anti-inflammatory medication which, in the opinion of the Investigator, could affect gingival condition.

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.

iii. 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.
• Teeth bleaching within 12 weeks of screening.
• Use of a chlorhexidine mouthwash within 14 days of baseline.
