Question 1

New Periodontitis classification

Answer 1

1. Periodontal health, gingival diseases and conditions
2. Periodontitis
3. Periodontal manifestations of systemic diseases and developmental and acquired conditions
4. Peri-implant diseases and conditions

Question 2

Periodontal health, gingival diseases and conditions

Answer 2

• Periodontal health and gingival health
• Plaque induced gingivitis
• Non plaque induced gingivitis

Question 3

Periodontal health and gingival health

Answer 3

*Clinical gingival health on intact periodontium
* Clinical gingival health on reduced periodontium

Question 4

Plaque induced gingivitis

Answer 4

• Associated only with plaque
• Mediated by systemic and local factors
• Drug influenced enlargement

Question 5

Non plaque induced gingivitis

Answer 5

• Genetic/developmental disorders
• Specific infections
• Inflammatory and immune conditions
• Reactive processes
• Neoplasms
• Endocrine, nutrional and metabolic diseases
• Traumatic lesions
• Gingival pigmentation

Question 6

Periodontitis

Answer 6

• Necrotising periodontal diseases
• Periodontitis as a manifestation of systemic diseases
• Periodontitis based on severity (CAL, bone loss) and complexity(PPD, furcation, mobility) of management
• Periodontitis based on extent and distribution
• Periodontitis based on evidence/risk of rapid progession (direct evidence by x-ray or CAL) and anticipated treatment response

Question 7

Necrotising periodontal diseases

Answer 7

• Necrotising gingivitis
• Necrotising periodontitis
• Necrotising stomatitis

Question 8

Periodontitis based on severity (CAL, bone loss) and complexity(PPD, furcation, mobility) of management

Answer 8

• Initial periodontitis
• Moderate periodontitis
• Severe periodontitis w/ potential for additional tooth loss
• Severe periodontitis w/ potential for dentition loss

Question 9

Periodontitis based on extent and distribution

Answer 9

• Localised
• Generalised

Question 10

Periodontitis based on evidence/risk of rapid progession (direct evidence by x-ray or CAL) and anticipated treatment response

Answer 10

• Slow rate of progession
• Moderate rate
• Rapid rate

Question 11

Periodontal manifestations of systemic diseases and developmental and acquired conditions

Answer 11

• Systemic diseases and conditions affecting periodontal supporting tissues
• Other periodontal conditions (Abcesses and endo-perio lesions)
• Muco-gingival deformities and conditions around the teeth
• Traumatic occlusal forces
• Prosthesis and tooth related factors that modify or predispose to plaque induced gingival diseases or periodontitis

Question 12

Muco-gingival deformities and conditions around the teeth

Answer 12

• Gingival phenotype
• Gingival and soft tissue recession
• Lack of gingiva
• Decreased vestibular depth
• Aberrant frenulum or muscle position
• Gingival excess
• Condition of exposed root surface

Question 13

Traumatic occlusal forces

Answer 13

• Primary occlusal trauma
• Secondary occlusal trauma
• Orthodontic forces

Question 14

Prosthesis and tooth related factors that modify or predispose to plaque induced gingival diseases or periodontitis

Answer 14

• Localised tooth related factors
• Localised dental prosthesis related factors

Question 15

Peri-implant diseases and conditions

Answer 15

• Peri-implant health
• Peri-implant mucositis
• Peri-implantitis
• Peri-implant soft and hard tissue deficiencies
