1. Classification of Periodontal Diseases and Conditions Dr. Sameer A. Mokeem
2. American Dental Association Classifications (ADA) The system developed by the American Dental Association classification
system is primarily based on the severity of attachment loss. The clinician uses the clinical and radiographic data gathered and classifies the patient into one of the four Case Types.
These Case Types are commonly required for insurance billing. In addition, the ADA provides treatment recommendations for each Case Type which is not part of this presentation.
3. American Dental Association Classifications (ADA) Case Type I: GingivitisCase Type II: Early PeriodontitisCase Type III: Moderate PeriodontitisCase Type IV: Advanced Periodontitis
ADA: Risk Management Series, diagnosis and Managing the Periodontal patient, 1986
4. American Academy of Periodontology (AAP) The American Academy of Periodontology classification system was established to identify distinct types of periodontal diseases by taking into consideration factors such as age of onset, clinical appearance, rate of disease progression, pathogenic microbial flora and systemic influences.
The two major categories are Gingivitis and Periodontitis.
Within each category there are specific types of diseases identified
5. Gingivitis Subdivisions Chronic Gingivitis
Acute Necrotizing Ulcerative Gingivitis
Gingivitis Associated with Systemic Conditions or Medications
Hormone-Induced Gingival Inflammation
Linear Gingival Erythema (LGE)
Gingival Manifestations of Systemic Diseases and Mucocutaneous Lesions
Bacterial, Viral or Fungal
Blood Dyscrasias (for example Acute Monocytic Leukemia)
Mucocutaneous Diseases (Lichen Planus, Cicatricial Pemphigoid)
6. Periodontitis Subdivisions Adult Periodontitis
Periodontitis Associated with Systemic Diseases
Necrotizing Ulcerative Periodontitis
7. AAP Classification The American Academy of Periodontology has recently published changes in theclassification system for periodontal diseases
These changes are from the 1999 International Workshop for a Classification of Periodontal Diseases and Conditions.
8. AAP Classification Conditions. Highlights of the changes are as follows:
Addition of a section on "Gingival Diseases"
Replacement of "Adult Periodontitis" with "Chronic Periodontitis
Replacement of "Early-Onset Periodontitis" with "Aggressive Periodontitis"
Elimination of a separate disease category for "Refractory Periodontitis"
Replacement of "Necrotizing Ulcerative Periodontitis" with "Necrotizing Periodontal Diseases"
Addition of a category on "Periodontal Abscess"
Addition of a category on "Periodontic-Endodontic Lesions"
Addition of a category on "Developmental or Acquired Deformities & Conditions" AAP 1999
9. Classification of Gingival DiseasesNon-Plaque induced gingival lesions 1. Gingival diseases of specific bacterial origin
2. Gingival diseases of viral origin

4.Gingival diseases of genetic origin
5.Gingival manifestations of systemic conditions
6. Traumatic lesions
7.Foreign body reactions
10. Classification of Periodontitis 1. Chronic Periodontitis*
2. Aggressive Periodontitis
3. Periodontitis Associated with Systemic Diseases
4. Necrotizing Periodontal Diseases
5. Abscesses of the Periodontium
6. Periodontal Diseases associated with Endodontic Lesions

*Can be further classified on basis of extent and severity
