  • enamel didn’t form
  • syphillus prenatal
  • screwdriver shaped
36
Q

mulberry molars

A
  • prenatal syphillus

- first molars

37

  • round
39
Q

taurodontism

A
  • bowl like tooth
  • enlargement of pulp chamber
  • crown look normal but short roots
  • lack of cervical constriction
40
Q

enamel dysplasia

A
  • disturbance during enamel development

- severity depends on how long disturbance lasted and stage it was in

41
Q

enamel hypoplasia

A
  • enamoblasts injury during enamel matrix formation
  • deficient matrix
  • ridges of enamel
  • caused by inflammation or high fever
  • enamel laying down
42
Q

enamel hypocalcification

A
  • enamel maturation
  • disturbed calcification (does not completely calcify)
  • white spots
43
Q

regional odontodysplasia

A
  • ghost teeth
  • enamel so calcified it flaked off
  • so thin teeth won’t erupt
44
Q

amelogenesis imperfecta

A
  • enamel matrix
  • no enamel or enamel deposited and doesn’t calcify
  • yellow/brown enamel
  • thin, pitted, various prone
  • teeth worn down
  • stained
45
Q

dental fluorosis

A
  • excessive fluoride
  • during enamel calcifying
  • caries resistant
  • chalky white turns brown from staining
46
Q

focal hypomaturation

A
  • white chalky area
  • localized, circular
  • trauma to deciduous tooth affects developing tooth bud/germ
  • enamel is soft
  • prone to caries, staining
47
Q

  • browning, pitting, discoloration
  • depression, not smooth
48
Q

tetracycline staining

A
  • antibiotic for pregnant women for infections
  • effects teeth of developing child
  • got deposited, staining teeth
  • extent depends on developing stage of baby and how long mother was on antibiotics
49
