Primary Outcome Measures :
  1. Plaque Index [ Time Frame: 6 weeks ]
    Plaque Index score scale 0 to 5 (0 = no plaque, 1 = separate flecks of plaque on the tooth, 2 = a thin continuous band of plaque,3 = a band of plaque up to one-third of the tooth, 4 = plaque covering up to two thirds of the of the tooth, 5 = plaque covering two-thirds or more of the crown of the tooth)

  2. Gingivitis Index [ Time Frame: 6 Weeks ]
    Gingivitis score- scale 0 to 3 (0 = no inflammation,1 = Mild inflammation-slight change in color and little change in texture 2 = Moderate inflammation-moderate glazing, redness, edema and hypertrophy. Tendency to bleed upon probing. 3 = Severe inflammation-marked redness and hypertrophy. Tendency to spontaneous bleeding)
