1999 Classification of Periodontal Disease

Study Notes

Classification of Periodontal Disease

Gingival Diseases: Classified under category I, involves inflammation of the gums without loss of attachment.
Chronic Periodontitis: Category II; most common form, characterized by slow progression and episodic nature. It can be influenced by systemic diseases.
Aggressive Periodontitis: Category III; rapid attachment and bone loss with unpredictable progression and high levels of Aggregatibacter actinomycetemcomitans (A.a).
Periodontitis as a Manifestation of Systemic Disease: Category IV; associated with systemic health conditions affecting periodontal status.
Necrotizing Periodontal Disease: Category V; involves necrosis of the periodontal tissues, often linked to systemic factors or immunocompromised states.
Abscesses of the Periodontium: Category VI; localized collections of pus within periodontal tissues.
Endo-Perio Lesions: Category VII; simultaneous occurrence of endodontic (root) and periodontal issues.
Developmental or Acquired Deformities and Conditions: Category VIII; includes anatomical abnormalities affecting periodontal health.

Gingival Diseases Overview

Plaque-Induced Gingival Diseases: Caused primarily by plaque biofilm and can be affected by systemic conditions, medications, and malnutrition.
Non-Plaque Induced Gingival Diseases: Result from factors like infections (bacterial, viral, fungal), genetic predisposition, systemic diseases, or trauma.

Aggressive Periodontitis Details

Characterized by rapid attachment loss and bone destruction; severity not consistent with the bacterial load.
Localized type primarily affects incisors and first molars.
Generalized type includes additional teeth along with incisors and first molars.

Chronic Periodontitis Specifics

Manifests as slow, site-specific progression, possibly related to systemic disease.
Subclassified based on extent/distribution and severity of clinical attachment loss.

Extent/Distribution of Chronic Periodontitis

Generalized: 30% or more sites with clinical attachment loss.
Localized: Less than 30% of sites affected.

Severity Classification

Slight: 1-2mm of clinical attachment loss (CAL).
Moderate: 3-4mm of CAL.
Severe: 5mm or more of CAL.

Graft Types in Periodontal Procedures

Autograft: Tissue harvested from the patient.
Allograft: Tissue from a donor of the same species but a different genotype.
Xenograft: Tissue sourced from a different species.
Alloplast: Synthetic materials designed for grafting.
