Study Notes
Classification of Periodontal Diseases
- Classification systems organize and name periodontal disease entities and conditions.
- A systematic arrangement of groups that share common attributes is necessary
- Classification aids in separating conditions into distinct categories for clinical and lab diagnosis & treatment.
- Classification helps determine disease etiology and improves communication among clinicians.
Outline of Topics
- Introduction
- Purpose of Classification System
- Dominant Paradigm in Historical Development of Periodontal Classification System
- AAP 1989 Classification
- AAP 1999 Classification
Introduction
- Classification is a systematic arrangement of groups sharing common traits.
- This arrangement clarifies the relationships between different groups and their members.
- Classification of disease is essential for distinguishing conditions for accurate clinical and lab diagnosis, and treatment.
- Classification of diseases affecting the periodontium helps identify the etiology and facilitates communication among clinicians, students, and epidemiologists.
Purpose of Classification System
- Accurate communication of clinical findings among dental health professionals and insurance providers.
- Providing patients with information about their disease.
- Formulating individualized treatment plans.
- Predicting treatment outcomes.
Dominant Paradigm in the Historical Development of Periodontal Classification System
- Development and evolution of periodontal disease classification systems are influenced by paradigms reflecting the understanding of periodontal disease's nature.
- Three main paradigms primarily guided thinking:
1. Clinical Characteristics Paradigm (1870-1920)
- Very limited knowledge of the etiology and pathogenesis of periodontal disease.
- Classification was predominantly based on clinical characteristics and unsubstantiated theories about its causes.
2. Classical Pathology Paradigm (1920-1970)
- Systems focused on general pathology principles.
- Periodontal diseases were categorized as dystrophic, atrophic, or degenerative.
- Gottlieb (1928) categorized periodontal diseases as inflammatory (Schmutz pyorrhea, diffuse alveolar atrophy, paradental pyorrhea) and degenerative/atrophic.
3. Infection/Host Response Paradigm (1970-Present)
- Systems are largely based on the infection/host response.
- Schluger, Yuodelis, and Page (1977) classified diseases into gingivitis (plaque-associated, ANUG, hormonal, drug-induced) and marginal periodontitis (adult, juvenile).
- Page and Schroeder (1982) further classified periodontitis as prepubertal (generalized/localized), juvenile, rapidly progressing, and adult.
AAP 1989 Classification
- A refinement of the 1982 Page and Schroeder classification.
- Categories: adult periodontitis; early periodontitis (may be prepubertal, juvenile, or rapidly progressive); periodontitis associated with systemic diseases; necrotizing periodontitis; refractory periodontitis.
- This categorization was based on the infection/host response paradigm, considering factors like patient age, disease progression, host factors, and therapeutic responses.
AAP 1999 Classification
- Includes a comprehensive section on gingival diseases.
- Replaced "adult periodontitis" with "chronic periodontitis" due to epidemiological evidence of chronic periodontitis in adolescents.
- Eliminated separate categories for rapidly progressive and refractory periodontitis due to a lack of sufficient evidence for differentiating conditions.
- Added new categories like "Aggressive periodontitis" (localized and generalized), and periodontal diseases as a manifestation of systemic diseases.
- Includes categories for abscesses of the periodontium and periodontic-endodontic lesions, alongside developmental/acquired deformities/conditions.
- Explicit types of gingival disease are included, including those induced by plaque, specific bacteria/infections, viruses, fungi, genetic factors, systemic conditions, medications, and malnutrition.
Gingival Diseases
- Different forms of gingival disease induced by plaque or from other causes, such as those from systemic factors/conditions
