Flashcards in anomalies Deck (44):
1

turners hypoplasia

pa inflammatory disease of deciduous teeth

2

what teeth are frequently affected by turners hypoplasia

perm premolars

3

what turners teeth are commonly injured

max CI

4

temporal line

line of deformed enamel

5

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

6

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

7

what enamel proteins are retained in fluorosis

amelogenin

8

fluorosis

hypomaturation of enamel that alters light reflection and gives white chalky areas

9

critical period to watch out for fluorosis

2nd/3rd years

10

what is too much fluoride

over 2 ppm

11

who passes on syphilis

untreated mother across the placenta

12

hutchinsons incisors

screwdriver ant teeth

13

mulberry molars

post teeth with constricted occlusal tables with disorganized surface anatomy

14

tooth wear

normal physiologic loss of dental structures

15

attrition

loss of tooth structure caused by TOOTH TOOTH contact

16

abrasion

pathologic wearing away of tooth structure by mechanical action of external agent

17

erosion

loss of tooth caused by nonbacterial chemical process

18

perimolysis

erosion from dental exposure to gastic secretions

19

abfraction

loss of tooth structure from occlusal stresses that create repeated tooth flexure with failure of enamel and dentin

20

ankylosis

anatomic fusion of tooth cementum or dentin within the bone

21

teeth frequently involved in ankylosis

primary mand 1st molar

22

t/f ankylosis rarely happens on permanent teeth

true

23

anodontia

lack of tooth development
rare and associated with ectodemal dysplasia

24

oligodontia

lack of 6+ teeth

25

most commonly missing teeth

3rd M, mand 2nd pms, max laterals

26

supernumerary tooth

single tooth hyperdontia

27

paramolar hyperdontial

supernumerary buccal or ling to molar tooth

28

where are natal/neonatal teeth

primary mand incisors

29

t/f in gemination, youll have 1 more tooth in the mouth

true. fusion will be the same

30

talon cusp

exaggerated cingulum

31

dens evaginatus is usually found

mand teeth, pm teeth
bilateral

32

t/f dens invaginatus is lined by enamel

true

33

dilated odontome

invagination dilates and disturbs root tooth formation

34

tx for den invaginatus

small - restore after eruption
large - endo or extraction

35

taurodontism

enlargement of the body and pulp chamber of a multi rooted tooth with apical placement of pulpal floor

36

amelogenesis imperfecta categories

hypoplastic
hypomatured
hypocalcified

37

hypoplastic amelogenesis imperfecta

inadequate deposition of enamel matrix, but whatever is put down is calcified
pinpoint pits generalized

38

hypomaturation AI

enough enamel, but it doesn't calcify
look normal, but quickly fall apart

39

characteristics of hypomaturation AI

snow capped pattern
mottle brown color, punctured by explorer
enamel chips

40

hypocalcified

enamel matrix laid down properly with no mineralization
enamel soft and easily lost

41

radiographic appearance with dentinogenesis imperfecta

translucent teeth
blue/brown discoloration
bulbous crowns
thin roots
obliteration of root canals and pulp chamber

42

dentin dysplasia

developmental defect of dentin

43

characteristics of dentin dysplasia type 1

rootless teeth
tooth mobility and premature exfoliation
pulpal obliteration
rarefying osteitis

44

characteristics of dentin dysplasia type 2

pulp chambers enlarged
thistle tube shaped or flamed shape
