21 Day Clinical Efficacy of Essential Oil Containing Mouth Rinses: Effect on Reducing Existing Gingivitis and Plaque

NCT02233998 NA COMPLETED Results posted

The reduction of existing plaque and gum inflammation will be evaluated using two marketed mouth rinses along with tooth brushing after 21 days of use compared to a placebo mouth rinse. 165 healthy volunteers will be enrolled in this three week study. Volunteers who qualify to be in this study will have an equal chance of being assigned to one of the three treatment groups. Volunteers will have a total of three visits including 1) Screening/Baseline Day 1 2) Day 11 (after 10 days of use) and 3) Day 22 (after 21 days of use). Volunteers will maintain a diary at home to record each treatment use and will be asked to come to the clinic without brushing or use their product for at least 8 hours, but no more than 18 hours. Examinations for oral hard/soft tissue, gingivitis, bleeding and plaque assessments will be completed at Screening/Baseline and repeated at Clinic Visit 3, which is Day 22.

• Mouth Rinse 2
• Mouth Rinse 3

Primary outcomes

• Whole Mouth Mean Modified Gingival Index (MGI) at Week 3 — 3 Weeks
  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.
• Whole Mouth Mean Plaque Index (PI) at Week 3 — 3 Weeks
  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.
