# 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.
