In staging
interdental CAL at the worst site
radiographic bone loss
tooth loss due to periodontitis
Describing the condition of which stage ?
Severity
Primary based on local factors like probing depth
For which stage ?
Complexity

What’s local extent of periodontitis ?
<30% of teeth
What’s generalized extent of periodontitis ?
> 30% of teeth
Which teeth consisted in pattern in periodontitis extent ?
Molar / incisors
When we have vertical bone loss = or > 3mm directly consider as class ?
3/4
When we have furcation involvement class 2/3 directly consider as stage ?
3/4
When we have < 20 teeth remain directly consider as stage ?
4
What’s determines the gradine ?
Rate of progression
Responsiveness to therapy
Assessment of risk
Rate of CAL / rapid bone loss
Smoking
Diabetes
Whats the direct and indirect evidence in grading?
Direct - radiographic bone loss , or CAL
Indirect - present of bone loss/ age
Case phenotype
How much radiographic bone loss or CAL in grade A ?
No loss over 5 years ( slow rate )
How much radiographic bone loss or CAL in grade B ?
<2 mm over 5 years ( moderate rate )
How much radiographic bone loss or CAL in grade C ?
> or = 2mm over 5 years
What’s the percent of bone loss/age in grade A ?
<0.25
What’s the percent of bone loss/age in grade B ?
0.25-1.0

> 1.0
What’s the case phenotype in grade A ?
Heavy deposits with little destruction
What’s the case phenotype in grade B ?
Destruction correlates = with deposits
What’s the case phenotype in grade C?
Destruction disproportionate to deposits
Minimal plaque
