Flashcards do conjunto (24)
- 1periapical cyst (apical periodontal cysts, radicular cyst)inflammatory odontogenic cyst
most common cyst
at PA of nonvital tooth, continous with PDL
arises from rests of malasezz, caused by caries
tx: endo or extraction - 2buccal bifurcation cystsinflammatory odontogenic cyst
found on buccal bifurcation of VITAL mandibular molar teeth with cervical enamel projection - 3radicular cystinflammatory cyst
found in edentulous areas with hx of tooth removal
typically left behind from previous PA cyst tx - 4dentigerous cystfollicular devl cyst
most common type of devl cyst
arises from dental follicle attached to the cervix, enclosing crown of an unerupted tooth
enlarged follicular cyst >4 mm
often impacted 3 molars
corticated border on radio (slow growing)
long standing cysts may contain rushton bodies
may undergo mucous prosoplasia
tx: curretage, marsupialization, bone graft - 5hyperplastic dental folliclelooks like dentigerous cyst: encloses unerupted tooth and is attached to CEJ
but surrounded by primative epi as opposed to stratifiedd sq - 6eruption cystdevelopmental cyst
formed around unerupted teeth
arises in soft tissue from rests of serres
found in 1/3 of infants in canine and molar region - 7globulomaxillary cystroots may diverge at junc of maxilla and premaxilla between LI and C
no developmental cysts can develop here: usually is a lateral PA cyst - 8lateral periodontal cystdevelopmental cyst that arises from DL rests of serres
occurs between vital teeth of adult males
found around mand PM and max incisors/canines - 9botryoid odontogenic cystpolycystic variant of the lateral periodontal cyst
developmental cysts that present as multiocular lucency associated with vital mand premolars of adults - 10gingival cyst of the adultsoft tissue counterpart of the lateral periodontal cyst
developmental cysts that arises from DL rests of serres
surrounds vital teeth of adult males in mand PM and max incisor/canine areas - 11dental lamina cyst of the newborngingival ODONTOGENIC cyst common on alveolar ridge of newborns
keratin-filled cysts arising from remnants of DL that spontaneously marsupialize - 12epstein pearlsepithelial rememnats from palatal shelf fusion found over midline of palate in newborns
non-odontogenic cysts
"pearls over palate" - 13bohn's nodulesepithelial remnants from minor salivary gland formation found on lateral palate in newborns
non-odontogenic cysts
"bohn over the bone" - 14odontogenic keratocystsmay be idiopathic or assoc with nevoid basal cell carcinoma syndrome (gorlin syndrome)
found in posterior jaws of teens and youg adults
aggressive growth and hi reccurrence (30%)
unilocular or multilocular
compact epi, no rete ridges, 6-8 cells thick
corrugated surface parakeratin
prominent, pallisaded hyperchromatic basal cell layer
remaining satelite cysts may cause reccurrance - 15primordial cystradiographic term for a cyst that develops in place of a tooth
usually an odontogenic keratocyst - 16orthokeratinizing odontogenic cystdevelopmental odontogenic cyst with a parakeratin lining
low/no recurrance and not assoc with a syndrome - 17calcifying odontogenic cyst "gorlin cyst"calcifying and keratinizing odontogenic cyst
anterior jaws of adults
RL to mixed
ghost cells
sometimes assoc with odontomas - 18glandular odontogenic cystodontogenic cyst with glandular features
anterior jaws of middle aged adults, usually mandible
multioccular, croses midline
aggresive, hi reccurance (30%) - 19oral lymphoepithelial cystscystic change of crypt epi of lymphoid aggregates
yg adults
floor of mouth, lateral tongue, tonsils
lined with epi and filled with keratin debris - 20cervical lymphoepithlial cysts branchial cleft cyst/fistulacystic change of branchial epi
upper lateral neck ant to SCM in yg adults
st sg epi lining exhibiting lymphoid tissue with germinal centers in wall - 21thyroglossal duct cystcystic change of thyroglossal duct epi
midline neck of yg people - 22nasopalatine duct cystmost common non odontogenic cyst of oral cavity
devl cyst that arises from epi rememnats of NP duct
vital teeth
middle aged/older adults
swelling, pain and RL 6mm - 23median palatine cystwell circumscribed palatine RL
epi entrapped during fusion of palatal shelves
st sq or pseudo strat columnar epi
difficult to dist from NP duct cyst - 24nasolabial cystsoft tissue cyst of upper lip lateral to midline
devl cyst from remnants of nasolacrimal duct
females
