Q

why do primary teeth tend to move within the bone as opposed to fracturing during trauma?

A

because the bone structure surrounding primary teeth isn’t as thick and dense as permanent teeth.

Q

what is the treatment for cellulitis?

which tooth is almost always the source of cellulitis?

A

number one thing is to put the kid on a high dose of amoxilcillin (clyndamycin or azithromycin if he/she is allergic to penicillins)

then we extract the tooth.

Q

What is the treatment of a chronic abscess?

A

no need for antibiotics according to Sorenson because it will do nothing for the symptoms because they are not bad.

need to extract the tooth an put in a space maintainer unless you can see the succedaneous tooth

Q

What is the treatment for acute abscess?

A

23
Q

what is the most common age to get the first herpetic lesion?

A

1.5-3 years of age

24
Q

leukemia’s and cancers of the brain = more than 50% of all childhood cancers. T/F

A

true

25
Q

What are the most common type of solid tumor in a child?

A

brain tumor (gliomas or medulloblastomas)

26
Q

due to their slow growth, odontomas are more considered hamartomas rather than true neoplasms. T/F

A

true

27
Q

what is the most common odontogenic tumor?

that tumor can interfere with what?

What are the two types

A

odontoma

can interfere with the eruption of permanent teeth

compound and complex.

28
Q

Compound Odontomas

occur most frequently where? typically associated with what tooth?

what are the symptoms?

A

occur most frequently in the anterior maxilla and commonly associated with an unerupted canine

these are typically asymptomatic but can delay the eruption of the permanent tooth

29
Q

Complex Odontomas

occur most frequently where?

can it cause a tooth to be missing?

A

posterior mandible

can cause a tooth to be missing if it arises from a normal tooth follicle

30
Q

what is the treatment for odontomas?

what is the prognosis?

A

simple local excision (often removing the tooth with it)

excellent prognosis because they don’t recur and are not invasive

31
Q

two teeth joined at the cementum is called what?

two teeth with two pulps but one clinical crown is called what?

A

concrescence

fusion

32
Q

What sometimes happens to permanent teeth when primary teeth fuse?

A

sometimes permanent teeth are missing if the primary teeth fuse.

33
Q

what is the most common tooth to have a dens invaginatus? be very specific

what is the common presentation?

what is the treatment before it gets infected?

A

maxilary permanent lateral incisor

common presentation is pulp necrosis and abscess

cover with sealant or restoration

34
Q

Cherubism may cause what to happen to primary teeth?

what does it do to permanent teeth?

A

may cause primary teeth to exfoliate early

may cause displacement of permanent teeth

35
Q

enamel hypoplasia can be caused by what vitamin and mineral deficiencies?

can be caused by what immune response?

can be caused by what very general type of drugs?

A

A, C, D, calcium and phosphorous

fever

antibiotics

36
Q

kids with cleft lip and palate are very likely to have hypoplasia. T/F

A

true

37
Q

T/F enamel hypoplasia can be caused by fluoride

A

True especially between birth and 4-5 years of age

38
Q

destructive lesions can be present on developing permanent teeth and are termed what?

A

pre-eruptive “caries”

39
Q

the anomaly characterized by a tendency for the body of the tooth to enlarge at the expense of the roots is called what?

A

Taurodontism

40
Q

Dentinogenesis imperfecta is also called what?

the disturbance occurs in which stage of tooth development

A

hereditary opalescent dentin

occurs in the histodifferentiation stage

41
Q

what is one of the most common inherited defects in man? (it has to do with teeth)

A

Dentinogenesis imperfecta type 2

42
Q

which type of dentinogenesis imperfecta does sorenson say has a shell tooth appearance on radiograph?

A

type 3

43
Q

Type 1 dentin dysplasia makes the pulp chambers look like what?

A

very small chevrons reaching from one root to the other

44
Q

Type 2 dentin dysplasia looks like what in the pulp of primary teeth?

what about permanent teeth?

A

pulp chambers are obliterated in primary

pulp looks like thistle tube in permanent teeth

45
Q

what is the most common type of amelogenesis imperfecta?

what is the enamel like?

A

hypocalcified type

pitted surface or “moth eaten” and soft enamel

46
Q

What is enamel like in the hypoplastic type of amelogenesis imperfecta?

A

hard thin enamel

makes for small teeth.

47
Q

What is enamel like in the hypomaturation type?

A

normal enamel thickness but low radiodensity and soft

fractures and flakes away

“snow capped” teeth

48
Q

anodontia may be part of what disease?

oligodontia may be part of what diseases?

A

ectodermal dysplasia

ecodermal dysplasia and down syndrome

49
Q

What is the defnition of hypodontia?
Which teeth are commonly missing in hypodontia

What is the definition of oligodontia?

A

agenesis of some (fewer than 6) teeth not including 3rd molars
typically the maxillary laterals and mandibular second premolars that are missing.

agenesis of more than 6 permanent teeth. (typically the last tooth in a series of teeth, 3rd molars, 2nd premolars, lateral incisors,

50
Q

what teeth are most commonly missing in ectodermal dysplasia?

what teeth are most commonly present?

A

mandibular incisors as well as Max/Man premolars

Max centrals
max canines
Max/Man first molars

51
Q

hyperbilirubinemia during tooth development will cause what?

blood decomposition in teeth will cause what?

A

discoloration of the teeth

discoloration of the teeth

52
