# Dental Grading ## Overview Veterinary dental disease staging, periodontal grading, and oral pathology classification using AVDC nomenclature. Includes dental charting systems and treatment planning by stage. ## When to Use - User presents a case or question involving dental grading in a veterinary context - User asks about species-specific approaches to dental grading - Keywords: dental, periodontal, tooth, oral, AVDC, gingivitis, periodontitis, extraction, dental chart, furcation ## AVDC Periodontal Disease Staging (PD 0-4) | Stage | Description | | --- | --- | | PD 0 | Clinically healthy gingiva | | PD 1 | Gingivitis only; no attachment loss | | PD 2 | Early periodontitis; < 25% attachment loss | | PD 3 | Moderate periodontitis; 25-50% attachment loss | | PD 4 | Advanced periodontitis; > 50% attachment loss | ## Furcation Index | Grade | Description | | --- | --- | | F1 | Furcation involvement < 1/2 the width of the tooth | | F2 | Furcation involvement > 1/2 but not through-and-through | | F3 | Through-and-through furcation exposure | ## Workflow 1. Confirm species and signalment (MANDATORY for clinical skills). 2. Gather relevant clinical history and examination findings. 3. Stage periodontal disease (PD 0-4) per AVDC nomenclature. 4. Assess furcation involvement (F1-F3) for multi-rooted teeth. 5. Apply species-specific protocols and reference ranges. 6. Consider breed predispositions relevant to this domain. 7. Reference current veterinary guidelines and cite sources. ## Key Species Differences Clinical approaches, drug choices, normal parameters, and common disease presentations differ by species. Never assume cross-species equivalence without explicit verification. ## Limitations - This skill provides clinical reference frameworks, not patient-specific treatment plans. - Physical examination and diagnostics are required for clinical decision-making. - Referral to a board-certified specialist should be considered for complex cases. - Evidence quality varies; some recommendations are based on expert consensus rather than RCTs.
