Primary outcomes

  1. Löe and Silness Gingival Index

    score from 0 to 3 will be assigned by the examining dentist to all scorable 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 scorable surface and dividing that number by the total number of surfaces scored.

  2. Rustogi Mod. Navy Plaque Index

    Time frame: baseline, 6 week, 12 week

    An expanded form of the Rustogi Modified Navy Plaque Index, used to measure plaque on different surfaces of teeth. Plaque disclosing solution used
