Trial Outcomes & Findings for A Clinical Trial to Test the Effect of Marketed Mouth Rinses on Decreasing Plaque and Gum Inflammation (NCT NCT02233998)

NCT ID: NCT02233998

Last Updated: 2015-08-21

Results Overview

Gingivitis was assessed on the buccal and lingual marginal gingivae and interdental papillae of all scorable teeth according to the following scale: 0: Normal (absence of inflammation), 1: Mild inflammation (slight change in color, little change in texture) of any portion of the gingival unit, 2: Mild inflammation of the entire gingival unit, 3: Moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the gingival unit, and 4: Severe inflammation marked redness, edema and/ or hypertrophy of the marginal or papillary gingival unit, spontaneous bleeding, congestion, or ulceration. The score for each participant was calculated by averaging their tooth site scores at Week 3.

PRIMARY outcome

Timeframe: 3 Weeks

Population: Analysis was based on the Full Analysis Set, which included all randomized participants who used at least one dose of the study product and had baseline and at least one post-baseline efficacy assessment.

Gingivitis was assessed on the buccal and lingual marginal gingivae and interdental papillae of all scorable teeth according to the following scale: 0: Normal (absence of inflammation), 1: Mild inflammation (slight change in color, little change in texture) of any portion of the gingival unit, 2: Mild inflammation of the entire gingival unit, 3: Moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the gingival unit, and 4: Severe inflammation marked redness, edema and/ or hypertrophy of the marginal or papillary gingival unit, spontaneous bleeding, congestion, or ulceration.

PRIMARY outcome

Timeframe: 3 Weeks

Population: Analysis was based on the Full Analysis Set, which included all randomized participants who used at least one dose of the study product and had baseline and at least one post-baseline efficacy assessment.

Plaque area was measured based on the Turesky modification of the Quigley-Hein Plaque Index and was scored on six surfaces (distobuccal, midbuccal, mesiobuccal, distolingual, midlingual, and mesiolingual) of all scorable teeth, following disclosing, according to the following scale: 0: No plaque, 1: Separate flecks or discontinuous band of plaque at the gingival (cervical) margin, 2: Thin (up to 1 mm), continuous band of plaque at the gingival margin, 3: Band of plaque wider than 1 mm but less than 1/3 of surface, 4: Plaque covering 1/3 or more, but less than 2/3 of surface, 5: Plaque covering 2/3 or more of surface. The score for each participant was calculated by averaging their tooth site scores at Week 3.

SECONDARY outcome

Timeframe: 3 Weeks

Population: Analysis was based on the Full Analysis Set, which included all randomized participants who used at least one dose of the study product and had baseline and at least one post-baseline efficacy assessment.

Bleeding was assessed using a periodontal probe with a 0.5 mm diameter tip which was inserted into the gingival crevice, and swept from distal to mesial, around the tooth at an angle of approximately 60 degrees, while in contact with the sulcular epithelium. Each of 4 gingival areas (disto-buccal, midbuccal, mid-lingual, and mesio-lingual) around each tooth was assessed. After approximately 30 seconds, bleeding at each gingival unit was recorded according to the following scale: 0: Absence of bleeding after 30 seconds, 1: Bleeding after 30 seconds, and 2: Immediate bleeding. The score for each participant was calculated by averaging their tooth site scores at Week 3.
