Brief summary
Rinse contains an anti-plaque agent that helps prevent the accumulation of dental plaque associated with gingivitis.
Detailed description
This is a prospective, single site, randomized, parallel, blinded clinical trial. Subjects will be randomly assigned to one of four treatment groups identified as Product A, Product B, Product C or Product D. Subjects will be screened for eligibility and entered into a washout period that is at least 7 days, during which time they will be provided with study toothbrush, toothpaste and dental floss. No oral rinses or medication that alters oral tissue health will be used or taken during the washout period. After randomization, the designated rinse will be placed into a non-transparent container so that other subjects and clinical examiners do not see the allocated rinse per the randomization schedule. Examinations for the clinical endpoints (PI, GI and BI) will be conducted at the baseline, 3-month, and 6-month visits. Interim visits will be scheduled to review diary, replenish study supplies, check study compliance, etc. Subjects will be provided Colgate Regular toothpaste, dental floss and a soft toothbrush (replaced at 3 months) for use during the 6-month study period.
Interventions
The Investigational Rinse contains a sugar-based surfactant using a proprietary formula. The intended use of the product is to help prevent and reduce plaque accumulation on the teeth and related gum-tissue inflammation (gingivitis).
The Placebo Comparator oral rinse is similar to the Experimental Oral Rinse only it does not contain the active ingredient.
PerioShield™ Oral Health Rinse (0.2% delmopinol hydrochloride) is marketed in the US and was purchased for use in this study.
Purified bottled water containing no active ingredients.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Plaque Index Score Per Participant at 6 Months | 6 months | Modified Quigley-Hein Plaque Index 0 = No plaque 1. = Separate flecks of plaque at the cervical margin of the tooth 2. = A thin, continuous band of plaque (up to one mm) at the cervical margin of the tooth. 3. = A band of plaque wider than 1 mm, but covering less than 1/3 of the crown of the tooth. 4. = Plaque covering at least 1/3, but less than 2/3 of the crown of the tooth. 5. = Plaque covering 2/3 or more of the crown of the tooth. Each tooth is scored for supragingival plaque on six surfaces: 1) mesio-facial; 2) mid-facial; 3) disto-facial; 4) mesio-lingual; 5) mid-lingual; and 6) disto-lingual. Third molars and those teeth with cervical restorations or prosthetic crowns will be excluded from the scoring procedure. The PI score of the individual can be obtained by adding the scores of all surfaces and dividing by the number of surfaces examined. |
| Gingivitis Index Score Per Participant at 6 Months | 6 months | Löe-Silness Gingival Index 0 = Absence of inflammation. 1. = Mild inflammation: slight change in color and little change in texture. 2. = Moderate inflammation: moderate glazing, redness, edema, hypertrophy. Tendency to bleed upon probing. 3. = Severe inflammation: marked redness and hypertrophy. Tendency to spontaneous bleeding. The gingival surface surrounding each tooth (all natural teeth) will be scored on six surfaces: 1) mesio-facial; 2) mid-facial; 3) disto-facial; 4) mesio-lingual; 5) mid-lingual; and 6) disto-lingual. Third molars and those teeth with cervical restorations or prosthetic crowns will be excluded from the scoring procedure. The GI score of the individual can be obtained by adding the scores of all surfaces and dividing by the number of surfaces examined. |
