From: A longitudinal assessment of periodontal disease in 52 miniature schnauzers
Score | Gingivitis | Periodontal probing depth (mm) | Gingival recession (mm) | Furcation exposure |
---|---|---|---|---|
Health (G0) | No gingivitis, pink (or pigmented) healthy gingiva, no inflammation and no bleeding on probing | <1 | 0 | 0 |
G1 | Very mild gingivitis (red, swollen but no bleeding on probing) | ≥1 | 0 | 0 |
G2 | Mild gingivitis (red, swollen and delayed bleeding on probing) | ≥1 | 0 | 0 |
G3 | Moderate gingivitis (red, swollen and immediate bleeding on probing) | ≥1 | 0 | 0 |
G4 | Severe gingivitis (ulceration, spontaneous haemorrhage, profuse bleeding on probing) | ≥1 | 0 | 0 |
PD1 | G1-G4: gingivitis must be present (i.e. active periodontitis) | >2 (>3 on canine teeth) | >0 | Grade 1; feel an indentation between the roots and the probe may advance 1 mm. |
PD2 | G1-G4: gingivitis must be present (i.e. active periodontitis) | >4 (>6 on canine teeth) | >2 (>3 on canine teeth) | Grade 2; obvious indentation between the roots and probe advances 50%. |
