Periodontal Disease Classification Flashcards

1969 Classification of Periodontal Disease

• 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.
