ERUPTION ANOMALY

INVOLVING CROWN

The tooth development is going outside

A

Leong’s premolar or dens evaginatus

25
Q

ERUPTION ANOMALY

INVOLVING CROWN

o Common in central or lateral incisors
o Usually central incisors with a notch on the
incisal edge

A

HUTCHINSON’S TEETH

26
Q

ERUPTION ANOMALY

INVOLVING CROWN

o Usually found on the upper central incisors on
the lingual side
o These are over-developed cingulum

A

Talon’s cusps

27
Q

abnormal space between teeth

A

Diastema

28
Q

anomalies which arise from an attempt at division of a single tooth germ by an invagination, with resultant incomplete formation of two teeth.

A

GEMINATION

29
Q

The structure is usually one with two completely or incompletely separated crowns that have a single root and root canal.

• ‘twinning’

A

GEMINATION

30
Q

Was described as a peculiar dental anomaly in which the body of the tooth is enlarged at the expense of the roots.

‘bull-like’ teeth

A

TAURODONTISM

31
Q

“Dens in dente”, tooth within a tooth

A

DENS INVAGINATUS

32
Q

A developmental condition that appears clinically as an accessory cusp or a globule of enamel on the occlusal surface between the buccal and lingual cusps of premolars, unilaterally or bilaterally, although it has been reported to occur rarely on molars, cuspids, and incisors

A

DENS EVAGINATUS

33
Q

An anomalous structure resembling an eagle’s talon, projects lingually from the cingulum areas of a maxillary or mandibular permanent incisor.

A

TALON CUSP

34
Q

ERUPTION ANOMALY

INVOLVING ROOT

• A form of fusion which occurs after root formation has been completed.
• In this condition, teeth are united by cementum only.

A

CONCRESCENCE

35
Q

ERUPTION ANOMALY

INVOLVING ROOT

Maxillary premolar with three roots rather than the usual two

A

Accessory roots/ supernumerary roots

36
Q

INVOLVING ROOT

extra enamel

A

Enamel pearls

rotation of a tooth
on its long axis

A

torsoversion

43
Q

crossing the line of occlusion

A

Supraversion

44
Q

away from the line of occlusion

A

Infraversion

45
Q

interchange in the position of
two permanent adjacent teeth located at the
same quadrant in the dental arch

A

Transposition

46
Q

if the position of the tooth is in the
other arch

A

Migration

47
Q

(IN RELATED TO RAMUS AND SECOND MOLAR)

Enough space between ramus and distal of
second molar

A

Class I

48
Q

CLASSIFICATION OF IMPACTION
(IN RELATED TO RAMUS AND SECOND MOLAR)

Mesiodistal width of the third molar crown can
pass

A

Class I

49
Q

CLASSIFICATION OF IMPACTION
(IN RELATED TO RAMUS AND SECOND MOLAR)

Space between the ramus and distal of second
molar is less than the mesiodistal width of the 3rd
molar crown

A

Class II

50
Q

CLASSIFICATION OF IMPACTION
(IN RELATED TO RAMUS AND SECOND MOLAR)

All or most of the third molar is located within the
ramus

A

Class III

51
Q

RELATIVE DEPTH OF 3RD MOLAR

Occlusal surface of the 3rd molar is the same
level as the occlusal surface of the 2nd molar

A

Position A

52
Q

RELATIVE DEPTH OF 3RD MOLAR

Occlusal surface of the 3rd molar is located
between cervical line and occlusal place of the
2nd molar

A

Position B

53
Q

RELATIVE DEPTH OF 3RD MOLAR

Occlusal surface of the 3rd molar is deeper than
the cervical line of the 2nd molar

A

Position C

54
Q

POSITION OF LONG AXIS OF THE 3RD MOLAR IN RELATION TO THE 2ND MOLAR

A

● VERTICAL
● HORIZONTAL

Q

is at or above cervical line of 2nd molar
