Q

Characteristics of necrotizing periodontitis

A

-Necrosis extending to the PDL and alveolar bone
-Rapid and destructive form of periodontitis that can produce attachment loss within days

Q

Characteristics of necrotizing stomatitis

A

-Necrosis extending beyond the gingiva to areas like the tongue, cheek and palate
-Bone stripping can occur through the alveolar mucosal tissue
-Most rare and severe form

Q

What is a pseudomembrane in PD?

A

-Grayish, yellow-white tissue slough over necrotic areas
-Consists of fibrin with leukocytes, erythrocytes and bacteria
-Not a true membrane

Q

How do interproximal craters form?

A

Within days the lingual papilla separate and a crater forms under the contact
Once formed, destruction invades the PDL and AB in NP.
