- Five categories defined: Gingivitis, Slight Periodontitis, Moderate Periodontitis, Severe Periodontitis, and Refractory Periodontitis.
1989 Classification of Periodontal Disease
- Five categories introduced: Adult Periodontitis, Early Onset Periodontitis (with subcategories: prepubertal, juvenile, rapidly progressive), Periodontitis associated with systemic disease, Necrotizing Ulcerative Periodontitis, and Refractory Periodontitis.
1999 Classification of Periodontal Disease
- Focused on Dental plaque-induced gingival diseases, categorized into four types:
- Gingivitis associated with dental plaque only
- Gingival diseases modified by systemic factors
- Gingival diseases modified by medications
- Gingival diseases modified by malnutrition
1999 Classification of Periodontal Disease (Current)
- Seven distinct categories include:
- Chronic periodontitis
- Aggressive periodontitis
- Periodontitis as a manifestation of systemic disease
- Necrotizing periodontal diseases
- Abscesses of the periodontium
- Periodontitis associated with endodontic lesions
- Developmental or acquired deformities and conditions
AAP Classification
- A verbal classification system introduced:
- Two terms for gingivitis (Type, Gingivitis)
- Four terms for periodontitis (Extent, Severity, Type, Periodontitis)
ADA Classification
- Four case types established for periodontal conditions:
- Case Type I: Health or Gingivitis
- Case Type II: Mild Periodontitis
- Case Type III: Moderate Periodontitis
- Case Type IV: Severe Periodontitis
ADA Case Type I
- Characterized by probe depths of 1-3 mm, no bleeding on probing (BOP), no clinical attachment loss (CAL), and no bone loss.
ADA Case Type IV
- Defined by probe depths of ~4 mm, 1-2 mm clinical attachment loss, potential class I furcation involvement, significant clinical attachment loss, possible class III furcation involvement, with over 50% radiographic bone loss.
