Inclusion criteria

* Males and females in good general health aged 18 to 70 years. * A willingness to read, understand, and sign the Informed Consent Form after the nature of the study has been fully explained to them. Subject should demonstrate a willingness to comply with all study procedures and sampling schedules. * A minimum of 20 natural teeth with facial and lingual scorable surfaces. * Adequate oral hygiene and no signs of oral neglect. * Good periodontal health. Enrolled subjects will have periodontal pockets no greater than 5 mm. * Gingival and plaque indices will also be measured during the first visit. Subjects with gingival index greater than or equal to 1.5 (Lobene Index) and plaque index greater than or equal to 1.5 (Turesky modification of Quigley-Hein Index) will be enrolled.

Exclusion criteria

* History of significant adverse effects following use of oral hygiene products such as toothpastes and mouthrinses. Allergy to personal care/consumer products or their ingredients. Previous known allergy to dental materials, particularly to acrylic-like materials used to fabricate the stent device (this is a highly unlikely occurrence). * Teeth that are grossly carious, fully crowned or extensively restored on facial and/or lingual surfaces, orthodontically banded, abutments, or third molars * Difficulty having dental impressions taken such as excessive gagging. * History of diabetes or hepatic or renal disease, or other serious medical conditions or transmittable diseases, e.g. heart disease or AIDS. * History of rheumatic fever, heart murmur, mitral valve prolapse or other conditions requiring prophylactic antibiotic coverage prior to invasive dental procedures. * Subjects on antibiotic, antiinflammatory or anticoagulant therapy during the month preceding the baseline exam. * Significant oral soft tissue pathology, systemically related gingival enlargement, severe gingivitis (based on a visual examinations). * History of active severe periodontal disease with bleeding gums and loose teeth. * Gross dental caries, severe generalized cervical abrasion and/or enamel abrasion, large fractured or temporary restorations (based on visual examinations).will not be included in the tooth count. * Fixed or removable orthodontic appliance or removable partial dentures. * Participation in a dental plaque/gingivitis clinical study involving oral care products, within the last 30 days.

After 14 days of study product use, the tongue was scraped 5 times with the edge of a tongue depressor. The sample is vortexed in sterile phosphate buffered saline(PBS) and the sample is then sonicated using a Branson 450A sonicator with a cup horn for 30 seconds. Samples diluted (10 fold) in PBS and plated using a spiral systems autoplate 4000 spiral plater on Veillonella Agar.
