Q

Define: concussion/subluxation injuries

A

Trauma to perio tissue without displacement out of the socket

Q

Tx aims for traumatised primary tooth

A
  • Pain relief
  • Maintain vitality
  • Prevent infection
  • Prevent damage to permanent successor
  • Maintain tooth in the arch (Function, aesthetics and space maintainer)

17
Q

Post op advice

A
  • Pain relief with OTC analgesics
  • Soft diet 2 weeks
  • OHI - gentle and use of CHX
  • Avoid sports
18
Q

Tx options for subluxation

A

Monitor if mild

Splint for 2 weeks to reduce discomfort

19
Q

Tx options for lateral luxation

A

If no occlusal interference = leave to spontaneously reposition, monitor
If occlusal interference = reposition with LA
If severe = extract

20
Q

Tx options for intrusion

A
  • If intruded TOWARDS tooth germ = remove

- If AWAY from tooth germ = retain and monitor for 6 months, if it hasn’t spontaneously extruded then extract

21
Q

Radiographic signs the tooth is intruded towards tooth germ -
What direction is it?

A

The apical tip is indistinct and tooth appears elongated

Palatal/lingual

22
Q

What direction is away from the tooth germ

A

Labially

23
Q

Management of extrusion

A
  • If minor (<3mm) or immature tooth primary tooth - reposition or allow spontaneous alignment
  • If severe or mature primary tooth - extract
24
Q

Management of avulsed primary tooth

A

DO NOT REIMPLANT AS IT WILL DAMAGE PERMANENT TOOTH

25
Q

What should be discussed with the parent

A

Long term sequelae on both the primary and permanent teeth

26
Q

Long term effects of traumatised primary teeth

A
  • Discolouration
  • Infection
  • Delayed exfoliation
27
Q

Long term effects to permanent teeth following trauma to primary tooth

A
  • Enamel defects - white, yellow or brown lesions (44%) or hypoplasia
  • Abnormal tooth/root morphology - dilaceration
  • Delayed eruption
28
Q

Describe discolouration changes to traumatised primary teeth

A
  • Immediate - red/brown
  • Weeks - brown/black
  • Months - yellow/opaque
29
Q

What ages are more susceptible to damage to the permanent successor? Why?

A

0-36 months as permanent teeth are still developing

30
Q

Most important long term sequelae for permanent teeth

A

Hypomineralisation +/- hypoplasia

31
Q

Management of subluxation

A

Monitor

If discolouration occurs, check for signs of infection and treat appropriately

32
Q

Management of root fracture

A

If no displacement of coronal fragment - leave and monitor but extract if signs of infection
If coronal fragment displaced, extract coronal segment and allow apical segment to resorb

33
Q

Why shouldn’t the apical fragment be removed

A

The permanent successor can be damaged in the process of removal

34
Q

Treatment of EDP fracture of a primary tooth

A

Restorable - Partial pulpotomy or pulpectomy

Extract if uncooperative or unrestorable

35
Q

Signs of crown-root fracture

A

Tooth loose but attached
Minimal to moderate displacement
RG may indicate the presence of a fracture line

36
Q

Signs of root fracture

A

Coronal fragment mobile and displaced

RG showing mid-root or apical third fracture

37
Q

Signs of concussion

A

Tender to touch

No mobility, sucular bleeding or RG abnormalities

38
Q

Signs of subluxation

A

Increased mobility but no displacement
Sucular bleeding
No RG abnormalities

39
Q

Signs of lateral luxation

A

Tooth displaced palatally or labially
Immobile
RG shows increased PDL space apically

40
Q

What view is important in lateral luxation

A

Occlusal to assess proximity of tooth to the successor

41
Q

Signs of extrusion

A

Elongated tooth
Excess mobility
RG showing incr PDL space apically

42
Q

Why should a radiograph be taken following avulsion of primary tooth

A

To ensure there has not been severe intrusion
