Yes Pediatric Oral Surgery And Oral Path

Front 1

What is second to third molars in frequency of impaction?

Back 1

maxillary permanent canines

Front 2

When does canine palatal impaction usually occur?

Back 2

Cusp tip of permanent canine is just mesial to or overlaying the distal half of the long axis of the root of the permanent lateral incisor

Front 3

Maxillary permanent canine impaction: frequency and gender

Back 3

3X more in females, 1-2 percent of population

Front 4

what is treatment of maxillary impacted perm canine?

Back 4

remove primary canine if perm canine has 2/3 root development

Front 5

What are the odds an impacted canine successfully repositions?

Back 5

if displaced perm canine overlap of adjacent lateral incisor not beyond midline of lateral, chances for canine normal repoistioning after primary canine extraction is 85 to 90 percent. if canine overlap is beyond lateral incisor long axis, successful repositioning is 60 percent

78 percent of ectopically erupting permanent canines normalized within 12 months after removal of the primary canines

Front 6

In terms of dental development, when do supernumerary teeth occur?

Back 6

initiation, proliferation stages

Front 7

how often does a supernumerary in the primary dentition result in supernumerary in permanent dentition?

Back 7

33 percent

Front 8

What percent of supernumerary teeth are found in maxillary arch?

Back 8

90 percent

Front 9

what percent of mesiodens erupt spontaneously?

Back 9

25 percent

Front 10

tubular vs conical mesiodens: which erupts more often?

Back 10

conical has a better chance of eruptin

Front 11

what percentage of newborns have Epstein's pearls?

Back 11

75-80 percent

Front 12

What are Epstein pearls? where do you find them?

Back 12

Median palatal raphe area, trapped epithelial remnants

Front 13

What are dental lamina cysts? where do you find them?

Back 13

crests of dental ridges, remnants of dental lamina

Front 14

Where are bohn's nodules? what are they?

Back 14

Buccal/lingual aspects of ridge, remnants of salivary gland epithelium

Front 15

what are Epstein's pearls, dental lamina cyst, and bohn's nodules filled with?

Back 15

keratin

Front 16

Where do you usually find congenital epulis of the newborn?

Back 16

anterior maxilla ridge

Front 17

how do you treat congenital epulis?

Back 17

excision

Front 18

excisional vs incisional biopsy

Back 18

Excisional biopsies: performed on small lesions, less than 1 cm in size, for the total removal of affected tissue.

Incisional biopsies: performed when a malignancy is suspected, lesion is large in size, or diffuse in nature

Front 19

what is the fixative biopsy samples are placed in?

Back 19

formalin ten percent

Front 20

what percent of the population has ankyloglossia?

Back 20

4-10 percent

Front 21

what sounds are hard for ankyglossed patients?

Back 21

s,z,t,d,l,j,zh,ch,th,dg and hard to roll an R

Front 22

what are the four classifications of maxillary frenums?

Back 22

1) mucosal (frenal fibers are attached up to the mucogingival junction)

2) gingival (fibers are inserted within attached gingiva)

3) papillary (fibers extending into the interdental papilla)

4) papilla penetrating (fibers cross the alveolar process and extend up to the palatine papilla)

Front 23

what type of maxillary frenums are most common?

Back 23

mucosal and gingival

Front 24

when should you surgically intervene for maxillary frenum?

Back 24

papilla blanches when upper lip is pulled or it causes a diastema wider than 2 mm

Front 25

natal vs neonatal teeth definition

Back 25

natal: present at birth

neonatal: erupt within 30 days of life

Front 26

Which syndromes have neonatal/natal molars

Back 26

pfieffer and histiocytosis X

Front 27

what is the condition where natal/neonatal teeth rub the tongue?

Back 27

riga fede disease

Front 28

what is more common natal or neonatal?

Back 28

natal 3:1

Front 29

thought process behind retrieving a fractured root tip?

Back 29

if the fractured root tip can be removed easily, it should be removed. If the root tip is very small, located deep in the socket, situated in close proximity to the permanent successor, or unable to be retrieved after several attempts, it is best left to be resorbed.

Front 30

with infections of the upper portion of the face, what should be ruled out because its symptoms are similar to odontogenic infection?

Back 30

sinusitis

Front 31

how much more often are supernumerary teeth found in the maxillary arch vs the mandibular arch?

Back 31

ten times more often in maxillary arch

Front 32

do you always have to extract primary supernumerary teeth?

Back 32

no, Primary mesiodens usually will erupt and does not need surgery, as the surgical intervention may disrupt or damage the underlying developing permanent teeth. erupted primary tooth mesiodens typically are left to shed normally upon the eruption of the permanent dentition

Front 33

can cytobrush technique, fine needle aspiration, and exfoliative cytology make a definitive diagnosis?

Back 33

no, they may assist in making a diagnosis, but they are considered adjunctive tests because they do not establish a definitive diagnosis
