5. No history of allergy to personal care consumer products, or their ingredients, relevant to any ingredient in the test products as determined by the dental/medical professional monitoring the study.
6. Dental Selection Criteria: Gingivitis patients with a minimum of 16 gradable teeth with a minimum of 6 sites with a GI score of ≥ 3. Subjects will be stratified according to gingivitis severity. Average full mouth GI score should be in the range of 2.0 - 2.5. heavy plaque formers should be avoided. Target a full mouth PI (Quigley-Hein) to be in the range of 1.5-3.0

Exclusion Criteria:

1. Subjects unable or unwilling to sign the informed consent form.
2. Medical condition which requires pre-medication prior to dental visits/procedures
3. Moderate or advanced periodontal disease
4. History of allergy to iodine
5. History of thyroid disease
6. History of diabetes
7. 2 or more decayed untreated dental sites at screening.
8. Other disease of the hard or soft oral tissues.
9. Impaired salivary function (e.g. Sjogren's syndrome or head and neck irradiation).
10. Use of medications that are currently affect salivary flow.
11. Use of antibiotics or antimicrobial drugs within 30 days prior to study visit #1.
12. Pregnant or nursing women.
13. Participation in any other clinical study within 1 week prior to enrollment into this study.
14. Use of tobacco products
15. Subjects who must receive dental treatment during the study dates.
16. Current use of Antibiotics for any purpose.
17. Presence of an orthodontic appliance.
18. History of allergy to common dentifrice ingredients
19. Immune compromised individuals (HIV, AIDS, immuno suppressive drug therapy)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Gingival Index	1 = Mild inflammation-slight change in color and little change in texture 2 = Moderate inflammation-moderate glazing, redness, edema and hypertrophy. Tendency to bleed upon probing. 3 = Severe inflammation-marked redness and hypertrophy. Tendency to spontaneous bleeding	6 weeks
EIBI Bleeding Score: Eastman Indterdental Bleeding Index Scale	0 = no bleeding or 1=spontaneous bleeding. Both upper and lower gums around each tooth in the mouth are checked for bleeding sites . The total number of 0 & 1 scores are added together and then divided by the total number of sites in the mouth evaluated to give the average number of bleeding sites in the mouth.	6 weeks
Plaque Index (Quigley-Hein Score)	Units on a scale 0 to 5 (0 = no plaque, 1 = separate flecks of plaque on the tooth, 2 = a thin continuous band of plaque, 3 = a band of plaque up to one-third of the tooth, 4 = plaque covering up to two thirds of the of the tooth, 5 = plaque covering two-thirds or more of the crown of the tooth)	6 weeks
