Q

How many teeth in the primary dentition are there

A

20

31
Q

T/F . A neonatal tooth that erupts within the first week after birth is not likely the primary tooth

A

f- it is

32
Q

What is the primate space

A

Maxillary arch= space between the lateral and the canine (mesial to canine)
Mandibular arch= space between the canine and 1st molar (distal to canine)

33
Q

Describe flush terminal plane and what occlusal class may arise in the permanent dentition

A

Normal relationship of the primary molar teeth (2nd molars on top and bottom are aligned)

Occlusal scheme- Edge to edge or Class I

34
Q

Describe distal step and what occlusal class may arise

A

Equivalent to a Class II (maxillary 2nd molar is more anterior relative to the mandibular)

Occlusal scheme= Class II or edge to edge

35
Q

Describe mesial step and what occlusal scheme may it give rise to in the permanent dentition

A

Mesial step= class I occlusion

Occlusal scheme= Class I or Class III

36
Q

Why is a equivalent Class III occlusion rarely seen in primary dentition

A

Mandibular growth lags behind the maxilla

37
Q

What is leeway space

A

Difference between the MD width of the primary canine, 1st, 2nd primary moalrs and the permenant canine, 1st and 2nd Premolars

38
Q

The position of the first permanent molars is determined by

A

primary molar position

39
Q

The relationship of the molars (Angles classification of occlusion) is determined by

A

mandibular growth

leeway space

40
Q

T/F Eruption cyst rarely requires tx

A

t- tooth should break through the tissue

41
Q

T/F Eruption cysts are only seen in the primary dentition

A

f primary and permanent dentition

42
Q

Eruption cyspts are most commonly seen where

A

molar region

43
Q

Compare and contracts fusion and gemination

A

Fusion

  • Will be short one tooth
  • Union of two primary/permanent teeth
  • Different from concressence because it also involves dentin (not just cementum)
  • Separate pulp chambers and pulp canals

Gemination

  • Normal number of teeth
  • Attempted division of a single tooth germ by invagination
  • Single pulp chamber
  • *Both demonstrate
  • familial tendency
  • more common in primary than permanent dentition- but can occur in both
  • Both will likely be missing the permanent successor
44
Q

What phase of growth does gemination occur in

A

proliferation stage

45
Q

What is ankylosis

A

Cementum fusion to surrounding bone

-PDL is replaced with osseous tissue rendering the totoh immobile to eruptive change

46
Q

The most common ankylosed teeth in the primary dentition are

A
  • Mandibular primary 1st molar
  • Mandibular primary 2nd molar
  • Maxillary primary 1st molar
  • Maxillary primary 2nd molar
47
Q

T/F Ankylosis can occur in primary and permanent dentition

A

t- more common in primary teeth

48
Q

Incidence of alkylosed teeth in primary dentition is

A

7-14%

49
Q

_ % of patients with one ankylosed tooth have more than one

A

50%

50
Q

In the permenant dentition ankylosis occurs most frequently after

A

Luxation injuries

51
Q

Ankylosis in the anterior teeth as a result of trauma is referred to as

A

replacement resorption

52
Q

T/F Ankylosed teeth exfoliate normally

A

t

53
Q

Ankylosed teeth (should/shouldn’t) be routinely removed? Exceptions?

A

Shouldn’t — exceptions are Large marginal ridge discrepancy

54
Q

What are the largest etiologic correlation to patterns of hypodontia (missing teeth)

A

family heredity

55
Q

When the primary tooth is absence it is (more/less) likely that the permanent tooth will also be absent

A

mroe

56
Q

What are the top 4 most commonly congenitally missing teeth

A
  • 3rd molars (10-25%)
  • Mandibular 2nd premolars (3.4%)
  • Maxillary Lateral incisors (2.2%)
  • Maxillary 2nd Premolar (0.85%)
57
Q

What are the calcification times for the four most commonly congenitally missing teeth

A
  • 3rd molars (Mandibular= 8-10 years and maxillary= 7-9 years)
  • Mandibular 2nd premolars (24-30 mo.)
  • Maxillary Lateral incisors (10-12 mo)
  • Maxillary 2nd Premolar (24-30 mo.)
58
Q

What are the manifestations of ectodermal dysplasia

A
  • No sweating
  • Sparse hair
  • Thick nails
  • Missing and abnormally sharped teeth
59
Q

What is the inheritance pattern of ectodermal dysplasia

A
  • X-linked recessive
  • Autosomal dominant
  • Autosomal recessive
60
Q

Supernumerary teeth can be associated with

A
  • Delayed eruption of permanent teeth
  • Ovder-retention of primary teeth
  • Deflection of roots with unusualy inclinations
  • Displacement of teeth
  • Diastemas
  • Abnormal root resorption
  • Formation of follicular or dentigerous cysts
61
Q

Supernumerary teeth are more frequently found in the (maxilla/mandible)

A

maxilla

62
Q

Is there a familial pattern with supernumerary teeth

A

yes

63
Q

It is (more/less) common to see supernumerary teeth in the primary dentition

A

less

64
Q

What is the most common supernumerary tooth

A

mesiodens

65
Q

90 % mesiodens are _ positioned

A

palatally

66
Q

_ % of mesiodens don’t erupt

A

75%

67
Q

Mesiodens teeth should be extracted when and what is the exception to this rule?

A

when 2/3-3/4 the root has formed (exception is if it is preventing the eruption of the permanent successor)

68
Q

What is a distodens

A

supernumerary tooth distal to molars

69
Q

If you have a patient with lingually erupted permanent mandibular incisors and the primary teeth did not exfoliate what should you do

A
  • If the patient is less than 8.2 years of age wait it out (see if the tongue and alveolar growth will push the permenant teeth forward and resorb the deciduous teeth)
  • Older than 8.2 y.o extract the corresponding baby teeth
70
Q

_% of ectopic molar erupts sel-correct

A

66% (22% in CLP)

71
Q

T/F The teeth in riga-fede disease should be extracted because it is causing a traumatic granulomatous ulcer on the tongue

A

F- these are the primary teeth smooth then with sof-lex discs

72
Q

Treatment options for Riga-Fede disease

A
  • Smooth teeth
  • Add resin
  • Modify feeding position
73
Q

Extraction of Riga Fede teeth indicated if

A
  • Supernumerary
  • Aspiration risk (mobile)
  • Feeding issues
74
Q

If a baby is under 10 days old and you need to do an extraction what should you do before the surgery and why

A

Give vitamin K (involved in prothrombin synthesis)- don’t have the gut flora to produce their own VitK
