Overview Flashcards
breakdown of peri-apical inflammatory lesion
- periapical cyst / granuloma
- condensing osteitis
- residual cyst
- apical scar
fibrosarcoma is what type?
malignant
SSC arises from? does not cause
arises from soft tissue and is destructive – probably will not see the maxillary sinus border but NO perisoteal reaction
non-hodgkins lymphoma look?
ENLARGED marrow space
- ragged spiculations on the borders
- INVADE PDL SPACES
leukemia
well-defined bone marrow space widening
pay attention to hte PDL spaces as well
PATCHY marrow spaces like lymphoma but leukemia occuring bi-modal (young and then old)
- if younger – PA of developing teeth
T/F metastic tumors are multi-focal
YES - true usually are
characteristic of condensing osteoitis
radiolucency at the apex
pseuodocyst aka
where and look like?
retention cys
going into max sinus - WD rounded corticated border expanding but not perforating the sinus
which has the radiolucent rim, odontoma or osteoma?
ODONTOMA
langerhan’s looks? malignant?
SCOOPED OUT
NOT MALIGNANT
Plasmocytoma is?
solitary lesion of multiple myeloma
within ramus
- ragged border
most common to displace tooth up into the sinus?
probably dentigerous cyst
anterior region in females “driven snow” calcification appearance
adenomatoid odontogenic tumor
cementoblastoma
describe
very round with thicker radio-lucent rim – SOFT TISSSUE capsule associated with root of a tooth
general expansion pattern of ‘round’ and internally is mixed
ossyfying fibroma
main one that is described as having multifocal radiolucencies
multiple myeloma
- punched out
calcifying cystic odontogenic tumor location and appearance
WD corticated with RL and 65% occur in the incisor/ canine region
*lingual tilting roots
BBC
Buccal Bifurcation Cyst
cysts that occur at the buccal bifurcation of mandibular molars in children. They can be bilateral but are not always. They tend to press against the roots of the molars, tilting the roots lingually (so the crowns face toward the buccal).
what pushes IAC superior?
Fibrous dysplasia
