May be a consequence of failures of the

Answer 3

coronal restoration rather than being due to failure of the root canal filling itself.

Question 4

Answer 4

operator errors

catastrophes

Question 5

Catastrophes usually result in

Answer 5

Question 6

Ledged canal more likely

Answer 6

IF greater than 30 degree curvature, and especially if you don’t have good access (file is getting deflected out of canal and you don’t have straight line access, ledge is more likely to happen).

MTA depending on location of root perforation

Question 8

MESIAL

Question 10

bleach incident - Most likely to occur in:

Answer 10

Maxillary posterior

Question 11

With bleach incident, DO NOT try to flush the tooth out with saline –

Answer 11

pushes it further down.

Question 12

Vital (Irreversible pulpitis or normal pulp):

Answer 12

thermal sensitivity should dissipate; no swelling expected because no “infection” (just tender gingiva from rubber dam clamp, or may feel swollen);
expect: tender to touch and biting; “achy” for up to 1 week.
Most of these patients feel better after treatment!

Question 13

Necrotic:

Answer 13

swelling may develop if it hasn’t already
may get worse before it gets better
always warn your patient of a “flare-up.”

Question 20

Nonhealed:

Answer 20

nonfunctional, symptomatic; with or without radiographic periradicular pathosis

Question 21

Healing:

Answer 21

periradicular pathosis present, but asymptomatic and functional; or, with or without radiographic pathosis, symptomatic but for which intended function is not altered

Question 22

Functional:

Answer 22

treated tooth or root that is serving its intended purpose in the dentition

Question 23

Luxations

Answer 23

(tooth moved)

Question 24

Crown fractures are more common in ———

Answer 24

primary dentition.

permanent dentition.

Question 25

Answer 25

crack
in enamel with no loss of
tooth structure

Question 26

Enamel fracture (uncomplicated
crown fracture):

Answer 26

fracture with loss

of enamel

Question 27

Enamel-dentin fracture (uncomplicated

crown fracture):

Answer 27

fracture with loss of
enamel and dentin, but not involving
the pulp

Question 28

Concussion -

Answer 28

Injury to tooth-supporting structures without abnormal loosening or displacement of the tooth, but with marked reaction to percussion

Question 29

Subluxation

Answer 29

Injury to tooth and supporting structures with abnormal loosening, but without displacement of the tooth

Question 30

Extrusive luxation

Answer 30

Partial displacement of the tooth out of its socket

Question 31

Lateral luxation

Answer 31

Displacement of the tooth in a direction other than axially; accompanied by comminution or fracture of the alveolar socket

Question 32

Intrusive luxation

Answer 32

Displacement of the tooth into the alveolar bone; accompanied by comminution or fracture of the alveolar socket

Question 33

RCT absolutely necessary when

Answer 33

pulp connection to periodontium has been severed (avulsion, extrusion, intrusion, lateral luxation, severe root fracture).

Question 34

Hyaline layer of Hopewell-Smith binds

Answer 34

cementum to dentin

Question 35

Lymphatics: in —–
Remove ——-
Drain into ——

Answer 35

periphery of the pulp

inflammatory exudates, transudates, cellular debris

submental, submandibular or cervical lymph nodes, then empty into the subclavian and internal jugular veins

Question 36

Sympathetic fibers alter

Answer 36

pressure, flow, distribution of blood at precapillary sphincters

Question 37

Sensory fibers release —— via axon reflexes - - this neurogenic inflammation mechanism results in increased blood flow and increased capillary permeability

Answer 37

neuropeptides

Question 38

Sympathetic motor innervation:

Answer 38

T1, C8, T2 via superior cervical ganglion – maintains vasomotor tone in precapillary sphincters which controls pressure and distribution of blood

Answer 39

parasympathetic
