41
Q

What is likely to happen with an intrusive luxation injury?

A

external root resorption

42
Q

What is the most severe luxation injury?

A

intrusive luxation injury

43
Q

What are the characteristics of an intrusive luxation injury?

A
  • Tooth appears shorter: displaced into alveolar bone
  • PDL destruction/alveolar crushing. Beware of ankylosis/resorption/
  • pulp necrosis is all but certain in
    mature teeth
  • Not tender to touch, not mobile
  • Percussion test: sounds different
  • Radiographs not always conclusive
44
Q

What is the treatment for intrusive luxation injury?

A
  • Slightly luxate with forceps or band and move orthodontically ASAP.
  • Splinting is place 14 days or more if alveolar fx is present.
  • Tooth with open apex may spontaneously re-erupt depending on the depth of penetration. (Less than 7mm)
45
Q

What is the RCT intervention for an intrusive luxation injury?

A

100%

46
Q

What is avulsion?

A

Tooth is knocked completely out of mouth

47
Q

Extra-oral dry time is CRITICAL _______ minutes for survival of PDL

A

0-15

48
Q

Must be replaced in socket immediately or ASAP (15-20”) in order to..

A

– Prevent external root resorption

49
Q

When considering avulsion the viability of the _____ must be preserved for success

A

PDL

50
Q

What is the replant treatment aimed at doing?

A

minimizing the inflammation from the two main consequences of avulsion:
1. attachment damage

Q

The SINGLE most important factor
in achieving a favorable outcome is the _______ at which a clean tooth is properly replanted (viable PDL) 15”

Q

Trauma to a tooth can stimulate the pulp to generate massive amounts of _____________. End Result is a sclerosed & non negotiable canal.

A

tertiary dentin

64
Q

Trauma to the pulp can cause the pulp to discontinue ________________

A

development
- remain at the stage present at the time of injury

65
Q

What is ankylosis (bone apposition)?

A
  • A problem following trauma and long term rigid splinting
66
Q

Tooth is solidly fixed and has a high different ring when ________. Does not erupt with other teeth

A

percussing

67
Q

What can ankylosis lead to?

A

May lead to massive external replacement resorption & loss of tooth

68
Q

What is the internal appearance of ankylosis?

A

appearance of “aneurysm”
w/in canal

69
Q

What are the characteristics of replacement ERR?

A
  • Patients are generally asymptomatic
  • Typically a history of avulsion or intrusion injury
70
Q

How can you tell if a tooth is ankylosis?

A

lack of normal mobility + High pitched “metallic ring” during percussion or possibly by “submergence” (not erupting with other normal teeth)

71
Q

Our professional responsibility includes educating our patients and the community regarding the dangers of trauma as well as appropriate preventive measures and therapeutic opportunities:

A

– Talk to school nurses
– Coaches
