   associated with an impacted tooth, esp. the ant. maxilla (e.g. canine) of     teenage females; expansive but             painless     Gross: very thick capsule Radiographic: well circumscribed RL w/ increasing RO over time of scattered calcifications; surrounds     crown & portion of the root, adjacent roots may be displaced Histo: duct-like appearing odontogenic structures, thick fibrous capsule, amyloid deposition rarely but not     as frequent as Pindborg tumor Tx: enucleation only (b/c thick capsule); no recurrence
3rd molars, 2nd premolars, lateral incisors -- females > males
What are the three most commonly missing teeth, and does it affect males or females more often?
. What disease advances its course by deposition of dense collagen in tissues and organs?  
Scleroderma (PSS); leads to mask-like facies, loss of ala of nose, and fibrosis of vital organs (fatal)
parotid gland -- it has a better prognosis than other tumors
Where is Acinic cell adenocarcinoma found most commonly?
False! Porphyrin staining is worse in decidious teeth because they are in enamel/dentin, and only in dentin of permanent teeth.
T/F: Porphyrins staining is worse in permanent teeth because they are in dentin and enamel.
What is Gorlin's sign and what is it associated with?          
 Hypermotility of tongue seen in Ehlers-Danlos syndromes - - touch the tip of the nose with the tip of the     tongue.
