Terms in this set (28)

cleiocranial dysplaisa

hyplaisa of the clavicles- hypermobiity of shoulder
- brachycepahlic skull
open fontanelles
- supernumerary teeth

supernumerary teeth
odontomas
- retained primary teeth
- osteomaas of the jaws, facial bones
- colon polyps ( malignant transformation)

amelogeneis imperfecta

dental anomaly
- 4 types
- hypoplastic
- hypomaturation
- hypocalcification and
combination of hypo maturation / hypocaclification

radipgraphic findings of amelogenesis imperfecta

- square crown
- relativ thin layer or absence of enamel
- low. absent cusps
- multiple open contact btwn teeth -
- anterior teeth : picket fence - type appearnce
- may have small pulp chambers bc of tertiary dentin

amelogenesis im

amelgoensis imperfecta
4 types
hypoplastic
hypomaturation
hypocalcification
- and combo of hypo maturation / hypo calcification

dentinogenesis imperfecta

genetic anomaly involving defective dentin
- may be associated wh osteogenEsis imperfecta ( type 1 )
type 2 - has no skelteal involvment

WHAT DOES PICKET FENCE TEETH REFER TO

anterior teeth of amelogenesis imperfecta

dentinogenesis imperfecta radio

bulbous crowns
-cervical portion of tooth is constricted
- slender roots
- partial. complete obliteration of pulp chamber root canals
- areas of apical rarefying osteiits

dentin dysplasia tpye 1

type 1 - radicular
- roots are short or ann shaped
- spontaneous exfoliation
- obliteration of pulp chambers ( before eruption)
- rarefying Osteitis with non carious teeth

dentin dysplasia type 1A1

- blunted roots - and obliterated pulp

- crescent shaped pulp
and shorte conical roots

2 crescent shaped pulp lines concave to each other at CEj
and roots of half N length
- molar roots are W shaped

- obliteration of pulp chamber and root canals ( after eruption )
- pulp chambers are flame or thistle shaped
- multiple pulp stones
- roots appear N

régional odontodysplaisa

enamel and dentin hypoplastic and hypoclacified
- large pulp chmabers / root canal
- also know as ghost teeth ***
- some erupt but generally don't erupt

supernumerary cusp -
hyperplaisa of the icnuglum of incisor
0

turners hypoplaisa

local hypoplastic defect in the crown
- from extension of PA inflammation of primary tooth
- manidbular premolars affected most often

neonatal lines of incisors

localized enamel hypoplasia

- caused by fever in childhood , exnathemaouts disease, congenital syphillis
- localized area affected
on particular part of crown

congenital syphillis

- hutchinson incisors and mulberry teeth

hutchinson inciors
- syphilis

mulberryy molars- syphillis

erosion -
radiolucent of crowns
- acid refluxed, bulimia

causes of internal resorption

acute trauma, direct . indirect pulp capping. pulpotomy

hypercementosis seeen in what disease
