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.

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

The American Academy of
Periodontology has recently published changes in the
classification system for periodontal diseases
These changes are from the 1999
International Workshop for a Classification of Periodontal Diseases and
Conditions.
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"
