gingival index
(Loe 1967) As for GI, normal gingival was scored as 0. 1 meant the presence of mild inflammation, slight change in color, slight edema and no BOP. Moderate inflammation was represented by 2, inclusive of the presence of gingival redness, edema, glazing and BOP. Severe inflammation with marked redness, edema, ulceration and spontaneous bleeding was scaled as 3
