Modified gingival index scoring system [37].

Score	Diagnosis	Modified Gingival Index Criteria	Color	Texture	Volume	Extent
0	Healthy	Absence of inflammation	Normal	Normal	Normal	None
1	Mild inflammation (partial unit)	Slight change in color, a little change in the texture of any portion of, but not the entire, marginal or papillary gingival unit	Slightly more reddish or bluish-reddish	Slightly glazy	Slight edema of the margin	Part of the gingival unit
2	Mild inflammation (entire unit)	Criteria as above but involving the entire marginal or papillary gingival unit	Slightly more reddish or bluish-reddish	Slightly glazy	Slight edema of the margin	Entire gingival unit
3	Moderate inflammation	Glazing, redness, edema, and/or hypertrophy of the marginal or papillary gingival unit	Red or reddish-blue	Glazy	Edema and /or hypertrophy of the margin	Entire gingival unit
4	Severe inflammation	Marked redness, edema, and/or hypertrophy of the marginal or papillary gingival unit, spontaneous bleeding congestion, or ulceration	Markedly red or reddish-blue	Spontaneous bleeding or ulceration	Edema and/or hypertrophy of the entire unit	Entire gingival unit
