Trial Outcomes & Findings for A Study to Determine the Effects of Adding an Experimental Device With Mouthrinse to Oral Care Regimen (NCT NCT01419626)

NCT ID: NCT01419626

Last Updated: 2019-12-17

Results Overview

Plaque area was scored using the Turesky modification of the Quigley-Hein Plaque Index (PI), on six surfaces (distobuccal, midbuccal and mesiobuccal, distolingual, midlingual and mesiolingual) of all scorable teeth, using following score range; 0: indicates no plaque; 1: separate flecks or discontinuous band of plaque on 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.

Population: FAS included all randomized participants who used study product and had baseline and at least one data for mean PI post baseline.

Gingivitis was assessed by the MGI on the buccal and lingual marginal gingivae and interdental papillae of all scorable teeth as per following score range: 0 indicates normal (absence of inflammation;) 1 indicates mild inflammation (slight change in color, little change in texture) of any portion of the entire gingival unit; 2 indicates mild inflammation of the entire gingival unit; 3 indicates moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the gingival unit. 4 indicates severe inflammation (marked redness and edema/hypertrophy, spontaneous bleeding, or ulceration) of the gingival unit.

Bleeding was assessed using the Gingival BI. A periodontal probe with a 0.5 millimeter (mm) diameter tip was inserted into the gingival crevice, and swept from distal to mesial around the tooth at an angle of approximately 60 degree, while in contact with the sulcular epithelium. Each of four gingival areas (distobuccal, midbuccal, mid-lingual, and mesiolingual) around each tooth was assessed. After approximately 30 seconds, bleeding at each gingival unit was recorded according to the following scale: 0 indicates absence of bleeding after 30 seconds; 1 indicates bleeding after 30 seconds; 2 indicates immediate bleeding.
