Gingival Examination
Evaluate tissue changes in terms of:
Color. Consistency. Contour.
Gingival Indices Used for evaluation and quantitation of
gingivitis.

Grade 0Grade 0 – normal gingiva, no inflammation, no – normal gingiva, no inflammation, no discoloration, no bleedingdiscoloration, no bleeding
Grade 1Grade 1 – mild inflammation, slight color change, – mild inflammation, slight color change, mild alteration of gingival surface, no bleedingmild alteration of gingival surface, no bleeding
Grade 2Grade 2 – moderate inflammation, erythema, – moderate inflammation, erythema, swelling, bleeding on probing or when pressure swelling, bleeding on probing or when pressure appliedapplied
