Periodontal Examination — Gingivitis and Plaque Grading

• Plaque Index (PI #)
• Calculus Index (CI #)
• Gingival Index (GI #)

Plaque Index (PI #)

• PI 0 — No observable plaque.
• PI 1 — Scattered plaque covering less than one-third of the buccal tooth surface.
• PI 2 — Plaque covering between one- and two-thirds of the buccal tooth surface.
• PI 3 — Plaque covering greater than two-thirds of the buccal tooth surface.

Calculus Index (CI #)

• CI 0 — No observable calculus.
• CI 1 — Scattered calculus covering less than one-third of the buccal tooth surface.
• CI 2 — Calculus covering between one- and two-thirds of the buccal tooth surface with minimal subgingival deposition.
• CI 3 — Calculus covering greater than two-thirds of the buccal tooth surface and extending sub-gingivally.

Gingival Index (GI #)

• GI 0 — Normal, healthy gingival with sharp, non-inflamed margins.
• GI 1 — Marginal gingivitis with minimal inflammation and edema at the free gingival. No bleeding on probing.
• GI 2 — Moderate gingivitis with a wider band of inflammation and bleeding upon probing.
• GI 3 — Advanced gingivitis with inflammation clinically reaching the mucogingival junction usually with ulceration. Periodontitis will usually be present.
