-Compound
What type of odontomas represent irregularly shaped masses?
-Complex
What is a traumatic bone cyst?
-Empty intrabony cavity that lack an epithelial lining
Where is the most common site of occurrence of a traumatic bone cyst?
-Mandible
When you see a radiolucent lesion in the mandible what is the first thing you do?
-18 gauge needle to do a needle aspiration
What does a mucocele result from?
-Rupture of a minor salivary gland
T/F Any location not on the lower lip that you think is a mucocele demands a biopsy
True

- they do not recur
why are traumatic bone cysts designated as pseudocysts?

antecedent
what is the hypothesis of the etiology of traumatic bone cysts?
- tramatically induced hematoma forms within intermedullary portion of bone
