Chapter 4 Classification of Periodontal and Peri-Implant Diseases and Conditions

Chapter 4 Classification of Periodontal and Peri-Implant Diseases and Conditions Section 2 The 2017 Classification of Periodontal and Peri-Implant Diseases and Conditions

Classification of Periodontal Health

Periodontal Health, Gingivitis, Gingival Diseases/Conditions Gingival Health Gingivitis-Biofilm induced Gingival Disease--Non biofilm-induced Clinical health on intact periodontium Associated with biofilm Genetic/developmental Clinical health on reduced periodontium Mediated by systemic and local factors Specific infection Drug-induced enlargement Inflammatory and immune Reactive process Neoplasm Endocrine, nutritional and metabolic Traumatic lesions Gingival pigmentation

Major Forms of Periodontitis

Necrotizing Periodontal Diseases Necrotizing gingivitis Necrotizing periodontitis Necrotizing stomatitis

Periodontitis as Manifestation of Systemic Disease Classification of conditions are based on the primary systemic disease

Periodontitis Four stages based on severity and complexity of management: Stage I: Initial periodontitis Stage II: Moderate periodontitis Stage III: Severe periodontitis with potential for additional tooth loss Stage IV: Severe periodontitis with potential for loss of the dentition

Periodontitis (cont.) Extent and distribution Grades: Grade A: Slow rate of disease progression Grade B: Moderate rate of disease progression Grade C: Rapid rate of disease progression

Other Conditions

Other Periodontal Conditions Periodontal abscesses Endodontic-periodontal lesions

Mucogingival Deformities and Conditions Around the Tooth Gingival phenotype Gingival/ soft tissue recession Lack of gingiva Decreased vestibular depth Aberrant frenum/muscle position Gingival excess Abnormal color Condition of exposed root surface

Traumatic Occlusal Forces Primary occlusal trauma Secondary occlusal trauma Orthodontic forces

Prostheses and Tooth-Related Factors Localized tooth-related factors Localized dental prostheses-related factors

Peri-Implant Diseases and Conditions

Comparison of the 2017 and 1999 Classification Systems Earlier literature will make references to chronic and aggressive periodontitis which is from the older system Good idea to be aware of the older classification system

1999 Classification System for Periodontal Diseases and Condition Gingival Diseases: Plaque-induced and non—plaque-induced Chronic Periodontitis Aggressive Periodontitis Periodontitis as a Manifestation of Systemic Diseases Necrotizing Periodontal Diseases Abscesses of the Periodontium Periodontitis Associated with Endodontic Lesions Developmental or Acquired Deformities and Conditions
