Q

aka dens evaginatus

A

occlusal tuberculated premolar
2. leong’s premolar
3.evaginated odontome
4. occlusal enamel pearl

30
Q

an accessory cusp of globule of enamel on the occlusal surface betweeen the buccal and lingual cusps of premolar. maybe unilateral or bilateral

A

dens evaginatus

31
Q

give 3 clinical significance of dens evaginatus

A
  1. maybe contribute incomplete eruption the teeth
    2.may contribute to displacement of the teeth
    3.May contribute to pulp exposure with
    subsequent infection following occlusal
    wear or fracture

give the clinical appearance

A

tauridontism

35
Q

give the clinical appearance of taurodontism

A
  1. seen both decidous or permanent teeth, but more common to permanent teeth
  2. may be unilateral or bilateral
36
Q

radiographic features of taurodontism

A
  1. rectangular in shape
    2.pulp chamber is extremely large with a much greater apico-occulusal height than normal
    3.pulp lacks constriction at rhe cervical of the tooth
    4.roots extremely short with bifurcation

its congenital

A

hutchinson’s teeth

42

associated with syphillis

45
Q

may involve both deciduous or permanent dentition

A

total anodontia

46
Q

cause of total anodontia

A
  1. failure of toothgerm to develop
    2.lack of initiation stage
47

pseudoanodontia

52
Q

teeth in excess of the normal number

A

supernumerary teeth

53
Q

possible causes of supernumerary teeth

A
  1. hereditary
  2. splitting of permanent tooth bud
    3.developed form a 3rd bud but arising form the dental lamina near the permanent tooth bud

neonatal teeth

58
Q

erupt at birth

A

natal teeth

59
Q

possibe cause ng neonatal teeth

A

1.arises form normal tooth germ that develops in a superficial position
2. lost spontaneously due to irregular structure of dentin and cementum
3. extracted to prevent them from being inhaled

60
Q

cause of premature eruption of primary teeth

A

due to superficial location of toothgerm

61
