odontogenic tumors Flashcards
what is in the bell stage of tooth development
dental lamina, enamel organ, dental papilla, dental follicle
cells in enamel organ
ameloblasts, enamel
cells in dental papilla
odontoblasts, dentin, pulp
cells in dental follicle
cementoblasts, cementum, pdl, alv bone
where can odontogenic tissues come from
odontogenic epithelium, ectomesenchyme, or mesenchyme and ectomesenchyme
where are odontogenic tumors located
in areas where teeth can form, most are central
t/f most odontogenic tumors are benign
true, grow from months to years, grow slowly
t/f most odonotgenic tumors are well circumscribed with a corticated border
true, but some are radiolucent, radiopaque, or mixed
radiolucent odonto tumors
ameloblastoma, ameloblastic fibroma, cental odotogenic fibroma, odontogenic myxoma
ameloblastomas are located where
molar/ramus area of mand
ameloblastoma
benign tumor of ameloblasts that does NOT produce enamel
t/f. ameloblastomas are slowly growing and locally aggressive
true
classic signs for ameloblastoma
soap bubble (multilocular, round septations) significant expansion
microscopically, ameloblastomas resemble
the enamel organ, you still see stellate reticulum and ameloblasts
tx of ameloblastoma
removal, including 1-2cm of surrounding bone
can recur, it infiltrates the bone
peripheral ameloblastoma tx
cut it off, its in the soft tissue, so you can get around it
ameloblastic fibroma consists of
odontogenic epithelium and ectomesenchyme (CT)
tx of ameloblastic fibroma
enucleation/curettage with good prognosis
what age does ameloblastic fibroma effect
under 20 (1st/2nd decade)
where is an ameloblastic fibrma usually
post mandible
