anomalies Flashcards
turners hypoplasia
pa inflammatory disease of deciduous teeth
what teeth are frequently affected by turners hypoplasia
perm premolars
what turners teeth are commonly injured
max CI
temporal line
line of deformed enamel
what do your teeth look like if you had a gnarly fever ages 2-3
rows of pits or diminished enamel on perm ant incisors and 1st molars
what do your teeth look like if you had a gnarly fever ages 4-5
rows of pits or diminished enamel on cuspids, bicuspids, and 2nd molars
what enamel proteins are retained in fluorosis
amelogenin
fluorosis
hypomaturation of enamel that alters light reflection and gives white chalky areas
critical period to watch out for fluorosis
2nd/3rd years
what is too much fluoride
over 2 ppm
who passes on syphilis
untreated mother across the placenta
hutchinsons incisors
screwdriver ant teeth
mulberry molars
post teeth with constricted occlusal tables with disorganized surface anatomy
tooth wear
normal physiologic loss of dental structures
attrition
loss of tooth structure caused by TOOTH TOOTH contact
abrasion
pathologic wearing away of tooth structure by mechanical action of external agent
erosion
loss of tooth caused by nonbacterial chemical process
perimolysis
erosion from dental exposure to gastic secretions
abfraction
loss of tooth structure from occlusal stresses that create repeated tooth flexure with failure of enamel and dentin
ankylosis
anatomic fusion of tooth cementum or dentin within the bone
teeth frequently involved in ankylosis
primary mand 1st molar
t/f ankylosis rarely happens on permanent teeth
true
anodontia
lack of tooth development
rare and associated with ectodemal dysplasia
oligodontia
lack of 6+ teeth
most commonly missing teeth
3rd M, mand 2nd pms, max laterals
supernumerary tooth
single tooth hyperdontia
paramolar hyperdontial
supernumerary buccal or ling to molar tooth
where are natal/neonatal teeth
primary mand incisors
t/f in gemination, youll have 1 more tooth in the mouth
true. fusion will be the same
talon cusp
exaggerated cingulum
dens evaginatus is usually found
mand teeth, pm teeth
bilateral
t/f dens invaginatus is lined by enamel
true
dilated odontome
invagination dilates and disturbs root tooth formation
tx for den invaginatus
small - restore after eruption
large - endo or extraction
taurodontism
enlargement of the body and pulp chamber of a multi rooted tooth with apical placement of pulpal floor
amelogenesis imperfecta categories
hypoplastic
hypomatured
hypocalcified
hypoplastic amelogenesis imperfecta
inadequate deposition of enamel matrix, but whatever is put down is calcified
pinpoint pits generalized
hypomaturation AI
enough enamel, but it doesn’t calcify
look normal, but quickly fall apart
characteristics of hypomaturation AI
snow capped pattern
mottle brown color, punctured by explorer
enamel chips
hypocalcified
enamel matrix laid down properly with no mineralization
enamel soft and easily lost
radiographic appearance with dentinogenesis imperfecta
translucent teeth blue/brown discoloration bulbous crowns thin roots obliteration of root canals and pulp chamber
dentin dysplasia
developmental defect of dentin
characteristics of dentin dysplasia type 1
rootless teeth
tooth mobility and premature exfoliation
pulpal obliteration
rarefying osteitis
characteristics of dentin dysplasia type 2
pulp chambers enlarged
thistle tube shaped or flamed shape
