Study Notes

Periodontal Classification Overview

A classification system for periodontal and peri-implant diseases aids clinicians in diagnosis and treatment, and supports scientific exploration of etiology, pathogenesis, natural history, and treatment.
The classification system is fluid, allowing for updates as new research emerges.

Purpose of Periodontal Classification System

Assists in diagnosing and treating periodontal and peri-implant diseases.
Enables accurate communication of clinical findings among dental healthcare providers.
Helps present disease status information to patients.
Facilitates prediction of treatment outcomes.
Provides necessary information for dental insurance submissions.

Historical Context

The American Academy of Periodontology (AAP) introduced its classification system in 1889, which was later updated in 1999.
The 1999 system featured eight classifications, including gingival diseases and categorized juvenile/early-onset periodontitis as "aggressive" and chronic periodontitis as "chronic".

Classification Details (1999)

Focused on extent (generalized vs localized), severity (slight, moderate, severe), rate of progression (aggressive vs chronic), and localization (gingiva vs bone loss).
The AAP and European Federation of Periodontology (EFP) collaborated to address unresolved issues from the 1999 classification.

Evolution of Classification System

The development of the classification system reflects emerging research in periodontology and the challenges of unifying various periodontal disease types under one classification.
In 2017, the AAP and EFP revised the classification system based on the latest evidence.

2017 Classification System

Introduces a more precise diagnosis through a multidimensional staging and grading system.
Stages 1-4 are determined by clinical attachment loss, bone loss, probing depth, and other criteria such as furcation involvement and tooth mobility.
Grades A-C indicate the risk of progressive periodontitis concerning systemic health, smoking exposure, diabetes control, and individual risk factors.

New Categories Introduced (2017)

"Periodontal health" is a new category not present in the 1999 system.
The "Gingival diseases and conditions" category incorporates the 1999 gingival diseases.
The "Periodontitis" category includes chronic periodontitis, aggressive periodontitis as a systemic disease manifestation, and necrotizing periodontitis.
The "Other conditions affecting the periodontium" category addresses abscesses, periodontitis tied to endodontic lesions, and developmental/acquired deformities.

Insights on Periodontal/Gingival Health

Healthy patients may exhibit features consistent with periodontal health rather than disease.
"Intact periodontium" versus "reduced periodontium" distinctions are made, with reduced periodontium occurring in stable periodontitis patients or non-periodontitis patients.
The revised classification groups previous "chronic" or "aggressive" forms into a single entity termed "periodontitis," emphasizing the lack of consistent evidence for them being distinct diseases.
