- Whole Mouth Lobene Modified Gingival Index Between the Brushing Only Group and the Brushing + Flossing Group [30 Days] Units on the MGI Scale [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
A whole-mouth average Lobene Modified Gingival Index was calculated by summing the scores and dividing by the number of sites graded (excludes missing teeth & sites not graded). Whole mouth average can range from 0 (normal) to 4 (severe inflammation).
For each tooth, six gingival areas (distobuccal, buccal, mesiobuccal, mesiolingual, lingual, and distolingual) were scored using the following scale: 0=Normal (Absence of inflammation, 1=Mild inflammation (slight change in color, little change in texture) of any portion of but not the entire marginal or papillary gingival unit, 2=Mild inflammation criteria as above but involving the entire marginal or papillary gingival unit, 3=Moderate inflammation (moderate glazing, redness, edema, and/or hypertrophy) of the marginal or papillary gingival unit, 4=Severe inflammation (marked redness, edema and/or hypertrophy, spontaneous bleeding or ulceration) of the marginal or papillary gingival unit.
