简要总结
Rinse contains an anti-plaque agent that helps prevent the accumulation of dental plaque associated with gingivitis.
详细描述
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.

- •Able to understand and willing to sign the Informed Consent
- •In good general health ages 18 and older
- •Have at least 20 natural teeth, including at least one molar and one premolar in each quadrant but excluding the third molars

排除标准
- •Subjects to whom these conditions apply will be excluded:
- •A history of antibiotic therapy within the previous 30 days or have a condition that is likely to need antibiotic treatment over the course of the study (eg, cardiac conditions requiring antibiotic prophylaxis such as heart murmurs, pacemakers, or prosthetic heart valves, and prosthetic implants)
- •A history of using antimicrobial oral mouth rinse during the past 3 months
- •Taking medications which may alter gingival appearance/bleeding

- •Advanced periodontal disease (purulent exudate, tooth mobility, and/or extensive alveolar bone loss)
- •Pregnant or nursing or plan to become pregnant within the 6 month study duration
- •Medical and oral conditions that, in the investigator's judgment, may compromise the subject's safety or interfere with the conduct and outcome of the study
- •Difficult to be compliant with study visits, such as extensive travel commitments or lack of transportation
结局指标
主要结局
Plaque Index Score Per Participant at 6 Months
时间窗: 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
时间窗: 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.
