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

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

3. Classification of Periodontal Health

4. 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

5. Major Forms of Periodontitis

6. Necrotizing Periodontal Diseases
Necrotizing gingivitis
Necrotizing periodontitis
Necrotizing stomatitis

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

8. 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

9. 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

10. Other Conditions

11. Other Periodontal Conditions
Periodontal abscesses
Endodontic-periodontal lesions

12. 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

13. Traumatic Occlusal Forces
Primary occlusal trauma
Secondary occlusal trauma
Orthodontic forces

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

15. Peri-Implant Diseases and Conditions

16. 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

17. 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
