CaOH

Answer 2

the fracture strength of calcium hydroxide-filled immature teeth will be halved in about a year? i.e. from in vitro study–long term Calcium hydroxide weakens teeth

Question 3

Answer 3

Cvek 1992

Question 4

Cvek 1992

cervical fracture?

Answer 4

if you lose vitality in an immature tooth that is not fully formed, there is increased risk of cervical fracture

Question 5

Three ways to decreases chance of ankylosis after a tooth has received trauma

Answer 5

1. splint should only be on for one to two weeks
2. endo should be done 7-10 days after trauma
3. leave CaOH2 in for one month

Question 6

Three types of resorption. Which is most common complication for avulsed teeth?

Answer 6

Surface, replacement, inflammatory. Replacement (bone fills in)-mos common complication for avulsed teeth.

Question 7

What clamp to use on primary molars?

Answer 7

13a

Question 8

Who showed that pulpotomy was very effective in eliminating pain initially and over 28 days. The intracanal medicament used (Cresatin, CMCP, Eugenol ZOE, Saline or dry cotton) was irrelevant and didn’t effect the results

Answer 8

Hasselgren and Reit 1989

Question 9

Hasselgren and Reit 1989

pulpotomy

Answer 9

Showed that pulpotomy was very effective in eliminating pain initially and over 28 days. The intracanal medicament used (Cresatin, CMCP, Eugenol ZOE, Saline or dry cotton) was irrelevant and didn’t effect the results

Question 10

Huang 2013 (regeneration)

Answer 10

Showed that human stem cells from apical papilla can regenerate dentin-pulp complex like tissue.

Question 11

Who showed that human stem cells from the apical papilla (scap) can regenerate dentin-pulp complex like tissue?

Answer 11

Huang 2013

Question 12

three major components for tissue engineering:

Answer 12

Cell source, physical scaffold, signaling molecules

Question 13

what is the tissue like in an internal cervical resorption lesion?

Answer 13

fibrovascular tissue with clastic cells adjacent to the dentin (can’t get past the unmineralized predentin that surrounds the pulp) (Heithersay 1999)

Question 14

predisposing factors for external cervical resorption? according to? reviewed by?

Answer 14

1 is ortho, #2 is trauma and bleaching. Heithersay (1999), reviewed by Patel 2009

Question 15

How much of root surface must be damaged to cause replacement resorption? Says who?

Answer 15

Andreasen, 20%

Question 16

cause of resorption? says who?

Answer 16

Trope. Damaged protective layer (predentin internally or cementum externally) with subsequent inflammation from noxious stimuli.

Question 17

Prognosis of permanent teeth with internal resorption? According to whom?

Answer 17

Turkun 1997: >90% with one week calcium hydroxide and warm gutta percha if no external perforation. 25% with perforation (1 in 4).

Question 18

Who said that you can differentiate external from internal resorption because you can trace the root canal through it, and it moves on shift shots?

Answer 18

Gartner and Mack 1976

Question 19

Gartner and Mack 1976 resorption?

Answer 19

you can differentiate external from internal resorption because you can trace the root canal through it, and it moves on shift shots

Question 20

Medication for avulsion?

Answer 20

Doxycycline bid for 7 days, unless <12 years old, then penvk for 7 days.

Question 21

Why use EDTA in regeneration? According to whom?

Answer 21

EDTA improves adhesion of stem cells to dentinal walls. Galler 2011

Question 22

Who had a 95% success rate with apical closure when necrotic immature teeth were treated with calcium hydroxide?

Answer 22

Cvek 1972

Question 23

Cvek 1972

Answer 23

95% success rate with apical closure when necrotic immature teeth were treated with calcium hydroxide.

Question 24

How do we define fractures now?

Answer 24

Uncomplicated (no pulp exposure) v. Complicated (pulp exposure)

Question 25

What is pH of Dycal?

Answer 25

pH of 12

Question 26

How soon after luxated or avulsed teeth are splinted should the splint be removed?

Answer 26

7-10 days

Question 27

Who said EDTA improves the adhesion of stem cells to dentinal walls?

Answer 27

Galler 2011

Question 28

Galler 2011 said what about EDTA?

Answer 28

That EDTA improves the adhesion of stem cells to dentinal walls
