NCT05120141 | Completed Phase 4

• 1 other identifier: CCSORC002549
• Study Type: interventional
• Target: 300
• Locations: 1 country
• Sites: 1

Brief Summary

The purpose of this study is to evaluate the safety and efficacy of experimental mouth rinse formulations compared to a hydroalcohol control mouth rinse and a positive control mouth rinse for the reduction of gingivitis and plaque when used as an adjunct to tooth brushing during a twelve-week product usage period.

Conditions

Gingivitis; Plaque

Outcome Measures

Primary Outcomes (2)

• Whole-mouth Mean Modified Gingival Index (MGI) Score After 12 Weeks of Product use

  Gingivitis will be assessed by the MGI on the buccal and lingual marginal gingivae and interdental papillae of all scorable teeth: 0 (Normal \[absence of inflammation\]), 1 (Mild inflammation \[slight change in color, little change in texture\] of any portion of the entire gingival unit); 2 (Mild inflammation of the entire gingival unit); 3 (Moderate inflammation \[moderate glazing, redness, edema, and/or hypertrophy\] of the gingival unit); 4 (Severe inflammation \[marked redness and edema/hypertrophy, spontaneous bleeding, or ulceration\] of the gingival unit).

  12 weeks

• Whole-mouth Mean Plaque Index (TPI) Score After 12 Weeks of Product use

  Plaque area will be scored by the Turesky modification of the Quigley-Hein Plaque Index, on 6 surfaces (distobuccal, midbuccal and mesiobuccal, distolingual, midlingual and mesiolingual) of all scorable teeth, following disclosing: 0 (No Plaque); 1 (Separate flecks or discontinuous band of plaque around the gingival (cervical) margin); 2 (Thin (up to 1 millimeter \[mm\]), continuous band of plaque at the gingival margin); 3 (Band of plaque wider than 1mm but less than1/3 of the surface); 4 (Plaque covering 1/3 or more, but less than 2/3 of the surface); 5 (Plaque covering 2/3 or more of the surface).

  12 weeks

Secondary Outcomes (4)

• Whole-mouth Mean TPI Score After 1 and 4 Weeks of Product use

  Weeks 1 and 4

• Whole-mouth Mean MGI Score After 4 Weeks of Product Use

  4 weeks

• Whole-Mouth Mean Expanded Gingival Bleeding Index (EBI) Score at 4 and 12 Weeks of Product use
