A

1/2

44
Q

About how long does it normally take normal blood flow to return to a traumatized tooth?

A

9 months (so pulp testing is useless in trauma)

45
Q

IF you were to do pulp testing following trauma, which teeth might it actually help with? What type of material would you use?

A

elderly teeth..use endo ice

46
Q

Do you have mobility or bleeding with a concussed tooth?

A

Nope

47
Q

Which radiograph do you use with a concussed tooth?

A

occlusial

48
Q

What % of concussed PEDO teeth have the chance of dying with pulp necrosis?

A

25%

49
Q

Which permanent tooth has a better prognosis with concussion?…open or closed apex?

A

closed actually…5% of necrosis

50
Q

If ankylosis starts to occur with a primary tooth and intrusion luxation, then what is the Tx?

A

EXTRACT THAT BEEZY

51
Q

What is the cardinal sign of subluxation?

A

bleeding from the sulcus

52
Q

What is a radiographic sign of subluxation?

A

PDL thickened

53
Q

If there is a subluxed permanent tooth, how long do you splint (if at all)?

A

2 weeks

54
Q

What is the risk of necrosis for a subluxed perm tooth with a closed root?

A

15%

55
Q

What are the two options of splinting wire used for trauma?

A

small ortho wire or monofilament fishing line

56
Q

What is the most complicated luxation injury? What is the most common complication with the healing of this injury and how long does it take to manifest?

A

Intrusional Luxation…ankylosed…5-10 years

57
Q

BOOM: How long do you splint for SUBLUX, Extrusion, Intrusion, Avulsion?

A

2 weeks

58
Q

BOOM: How long do you splint for LATERAL luxation, and delayed avulsion?

A

4 weeks

59
Q

Which type of displacement injury is this? Tooth will appear elongated ++Mobility, tender to percussion
Pulp test will be negative
Radiograph will display increased PD

A

Extrusion Luxation

60
Q

What is the limit distance of extrusion in a primary luxated tooth before extraction is to take place?

A

more than 3mm

61
Q

the need to splint an _________ luxated primary tooth is likely an indication for extraction

A

extrusively

62
Q

How many radiographs do we want for a permanent extrusion luxaiton?

A

the 3

63
Q

Which has the best survival chance in a permanent extrusion lunation-a mature apex or open apex?

A

open

64
Q

Say a PRIMARY tooth is labially (root to the lingual) luxated….what is the best Tx choice?

A

Extraction (don’t want to damage incoming incisors)

65
Q

For a lateral luxation of a primary central or lateral incisor at what age might it be ok to reposition BECAUSE the permanents are DONE calcifying?

A

5 years old (so they can keep their central for another 2 years…)

66
Q

How long do you splint a permanent lateral luxation?

A

4 weeks (get it set ASAP!)

67
Q

An open apex has the best chance of survival on a permanent tooth lateral luxation, BUT overall what is the % chance the tooth will need RCT?

A

75%

68
Q

What two diagnostic tests are not likely to succeed in an intrusion luxation?

A

percussion or mobility (the tooth is shoved into the bone!)

69
Q

Primary tooth, Intrusion Luxation: if it is toward the labial what is the possible outcome?

A

SPONTANROUS RE-ERUPTION

70
Q

Primary tooth, Intrusion Luxation: if it is toward the lingual what is the possible outcome?

A

Extraction (don’t want it messing up the permanent tooth-until 5 y/o)

71
Q

Primary tooth, Intrusion Luxation: WHAT PERCENT? of intruded teeth will re-erupt spontaneously (either partially or completely) in HOW LONG OF TIME? HOW LONG IS THEIR SURVIVAL TIME?

A

90%….2 to 6 months…survive for 3 years!!

72
Q

If ankylosis starts to occur with a primary tooth and intrusion luxation, then what is the Tx?

A

EXTRACT THAT BEEZY

73
Q

What is the critical factor in intrusion luxation of a permanent tooth? What is the tx?

A

ROOT MATURITY…spontaneous re-eruption OR ortho..worst case-immediate reposition and splint/ortho

74
Q

Intrusion luxation: What is the threshold for when an OPEN apex tooth is intruded to rely on spontaneous re-eruption?

A

Less than 7mm of intrusion!!

75
Q

Intrusion luxation: What is the threshold for when a CLOSED apex tooth is intruded to rely on spontaneous re-eruption?

A

Less than 3mm of intrusion

76
Q

What is the ONLY treatment option for a closed apex tooth that has been luxated intrusionally more than 7mm?

A

surgery

77
Q

Say you are trying to get spontaneous re-eruption of a tooth…how long do you wait to see if other treatment is needed?

A

“a few weeks”

78
Q

What is the most complicated luxation injury? What is the most common complication with the healing of this injury and how long does it take to manifest?

A

Intrusional Luxation…ankylosed…5-10 years
