What are the probing characteristics of periodontal stability vs gingivitis?

Under 10% BOP, 3mm or under probing depth

Localised- 10-30%, generalised-over 30%, over 3mm depth

Why is the Armitage classification no longer used?

Hard to establish clear diagnosis

Didn’t include many clinical forms- so now use American association 2017
