Answer 1

• Sharply well defined borders
• Can be corticated
• Displaces normal structures
• Expands rather than perforates cortical plate.

Question 2

What are radiographic features of rapid growth?

Answer 2

• No well defined
• Destroys normal structures
• Perforation of cortical plate more common

Question 3

WHat are the clinical features of cysts?

Answer 3

• Well defined
• Corticated borders common
• Hydraulic appearance
• Can cause expansion

Question 4

What are clinical features of benign tumors?

Answer 4

• Well defined
• Usually corticated
• Displaces structures
• Can cause expansion

Question 5

Answer 5

• Usually has poorly defined borders.
• Pain variable
• Can have surrounding sclerotic bone

Question 6

What are radiographic features of malignant neoplasms?

Answer 6

• poorly defined
• Widens PDL space irregularly
• Irregular resorption of roots
• May cause expansion but will perforate cortex

Question 7

What is Enucleation, Curettage, and Peripheral Ostectomy?

Answer 7

Enuc= Removal of lesion only.
Curre= Removal of lesion with surrounding bone with hand instrument.
