Q

replacement resorption (enkylosis)

A

happens after irreversible injury to the pdl

should be extracted if they cause a delay in or ectopic eruption of a developing perm tooth

Q

how to treat intrusion

A

no tx, let tooth re-erupt
do not reposition or splint

16
Q

t/f the theraputic approach to treating intrusion is widely accepted

A

false. its controversial

17
Q

what other defects are common with intrusion injuries

A

hypoplasia and arrest of tooth development

18
Q

should you reposition teeth that have underwent subluxation

A

no

19
Q

what may happen during the first 6 mo after a luxation injury

A

pulpal necrosis and the crown can appear gray or gray-black

20
Q

what do you do if the crown of a tooth turns gray after a luxation injury

A

NOTHING. leave it alone if it is asymptomatic and no pathology is noted

21
Q

t/f. there are 5 reliable methods of determined pulp vitality

A

false. there is no reliable method

22
Q

will traumatized teeth respond to vitality testing?

A

no

23
Q

what is the most reliable vitality test

A

thermal test (especially in prim incisors)

24
Q

t/f. 80% of primary incisors that are darkened due to injury are symptomatic

A

false. asymptomatic

25
Q

what should one use to reduce the chance of bacterial invasion of pdl after trauma

A

0.12% chlorhexidine oral rise

26
Q

transportation media for avulsed teeth

A 
viaspan
hanks balanced salt solution
cold milk
saliva (buccal mucosa)
physiologic saline
water
27
Q

pulpal therapy options

A

indirect pulp cap, direct pulp cap, pulpotomy

28
Q

indirect pulp cap

A

near pulp, but no exposure

GI used more than CaOH

29
Q

diect pulp cap

A

only indicated in primary teeth when a pinpoint pulp exposure is encountered during cavity prop of following trauma
contraindicated in tooth with carious pulp exposure
MTA or CaOH

30
Q

pulpotomy

A

carious pulp exposure w/o evidence of radicular pathology
use formocreosol or ferric sulfate
ZOE base

31
Q

how do you achieve hemostasis is a pulpotomy procedure

A

viscostat (ferric sulfate)

32
Q

how is ZOE applied during a pulpotomy procedure

A

after you remove excess ferric sulfate, mix the ZO powder and eugenol liquid until it can be rolled up into a ball and cover the entrance to the canals until half the pulp chamber
GI then fills the rest and a SS crown is placed

33
Q

t/f formocresol has been challenged as a potential carcinogen and mutagen

A

true

34
Q

t/f pulpotomies performed with either formocresol or ferric sulfate are likely to have similar clinical/radiographic success

A

true

35
Q

t/f. ferric sulfate and formocresol pulpotomies can lead to premature exfoliation of primary teeth

A

true

36
Q

t/f there is no significant difference bt the total success rate of formocresol and ferric sulfate pulpotomy

A

true
