Clinical Study Examining the Control of Plaque and Gingivitis

Gingivitis Assessment

A Loe-Silness Gingival Index score from 0 to 3 will be assigned by the examining dentist to all scoreable surfaces of the maxillary and mandibular teeth using a dental light and dental mirror. A whole mouth mean score for each subject will be determined by adding the values given by the examining dentist to each scoreable surface and dividing that number by the total number of surfaces scored. 0 = Absence of inflammation 1. = Mild inflammation - slight change in color and little change in texture 2. = Moderate inflammation - moderate glazing, redness, edema and hypertrophy 3. = Severe inflammation - marked redness and hypertrophy. Tendency for spontaneous bleeding Each tooth is scored on six surfaces: mesio-facial; 2) mid-facial; 3) disto-facial; 4) mesio-lingual; 5) mid-lingual; and 6) disto-lingual. The maximum score per tooth, therefore, is 18.

Time frame: Baseline, 3 month, 6 month

Quigley-Hein Plaque Index

First using a red solution to dye the plaque, a Quigley-Hein Plaque Index score of 0 to 5 will be assigned to all scoreable disclosed surfaces of the maxillary and mandibular teeth using a dental light and dental mirror. A whole mouth score for each subject will be determined by adding the values given by the dental examiner to each scoreable surface and dividing that number by the total number of surfaces scored.
