Periodontitis & Other Conditions Affecting the Periodontium

1
Q

What is Periodontitis

A

a complex microbial infection that triggers a host-mediated inflammatory response within the periodontium, resulting in progressive destruction of the PDL and supporting alveolar bone.

Q

Why were the two subgroups of the 1999 Disease Classification of Periodontitis eliminated from the 2017 disease classification?

A

The two subgroups (chronic periodontitis and aggressive periodontitis) were eliminated because there is little consistent evidence that aggressive and chronic periodontitis are different diseases.
