Q

Features of external root resorption

A
  • Non vital teeth
  • Damage to PDL (usually luxation injuries)
  • Toxins from pulp space → dentine tubules → inflammation and resorption of root surface

18
Q

Treatment of cervical resorption

A

if vital - curettage and MTA/CaOH lining followed by resto

non vital - RCT and then as above

19
Q

How to diagnose internal root resorption

A

Clinical: Pink discoloration of crown

Radiograph: resorption of pulp space, rounded symmetrical radiolucency

20
Q

Treatment of internal RR

A

RCT

21
Q

How does ankylosis / replacement resorption occur?

A
  • Luxation injuries causes significant damage to PDL →
  • PDL repair with bony replacement
  • Rate of repair dictates rate of root replacement
22
Q

Other name of ankylosis

A

Replacement resorption

  • Damaged PDL is replaced with bone
23
Q

How to diagnose ankylosis clinically (2)

A

Ankylotic sound - high pitched, solid sounding metallic tone

May appear to be submerging in growing child

24
Q

How to diagnose ankylosis radiographically

A

May show signs of replacement resorption

  • Loss of PDL
25
Q

Treatment of ankylosis (3)

A

May leave to monitor and allow it to take over root

Decoronation

Non vital teeth: RCT and dressing - no GP

26
Q

How can trauma to primaries affect the permanent dentition? (7)

A
  1. Enamel defects
  2. Dilaceration
  3. Malformation
  4. Odontoma-like formation
  5. Duplication
  6. Arrested development
  7. Eruption disturbances
27
Q

Why dont you put GP in ankylosed teeth?

A

Tooth root will eventually be replaced by bone → only CaOH NO GP

28
Q

What to do?

A

Tooth has completely intruded

  • Allow time for tooth to spontaneously re-erupt
  • Damage was already done to successor at time of trauma

If doesnt come down, GA and remove before it gets ankylosed

29
Q

What do you do - tooth is mobile

A

Option 1: Do nothing - advise parents that tooth may fall out soon on its own

Option 2: Extraction but usually parents will want to keep front tooth for longer

30
Q

What is happening?

A

Displacement and impaction of mx permanent incisors as a result of inflammation infection from primaries

31
Q

what is this and what caused it

A

Enamel defect as a result of injured primaries

32
Q
A

dilaceration

33
Q

When should RCT be performed following luxation injury?

A

When tooth has been intruded or avulsed, neurovascular bundle is severed and PDL is affected

  • If tooth has complete root development (apex intact) at time of injury, its assumed tooth will have pulpal necrosis → RCT to avoid external inflammatory root resorption

IF tooth is IMMATURE (ex. child 9, root tip not closed) → give it a chance. NO ENDO (exo after 3 weeks if problematic)

34
Q

Potential outcomes related to root injury ** (4)

A

Transient apical breakdown

Transient Marginal breakdown

Gingival reattachment

PDL reattachment

35
Q

Differenc between PDL healing/damage reaction vs pulpal

A

Pulpal a lot easier to manage → LEO can stay and not affect tooth

PDL radiolucencies → “alarm bells” needs endo asap to save inflammatory root resorption

36
Q
A

External inflammatory root resorption

  • Toxins from pulp space entered tubules causing inflammation and resorption of root surface

In this particular pic both bone and PDL are being resorbed // URGENT

37
Q

Describe the urgency for LEO alone vs PDL resorption

A

LEO alone - not urgent / PDL intact

Luxation injuries causing PDL resorption = URGENT endo to save structure

38
Q

What injuries cause PDL resorption (urgent care)? (3)

A

Lateral luxation

Intrusion

Avulsion

39
Q

When to recall for PDL injuries

What to look out for

A

3-4 weeks

PDL resorption / inflammatory root resorption on lateral wall

40
Q

What to do for immature perm tooth (apex not formed) with punched out lesions on PDL

A

Extirpate

  • Once stability is achieved → reassess
  • If compromised, unrestorable → Exo
  • If OK → Apical barrier / MTA and dress
41
Q

What to do for primary tooth with punched out lesions on PDL

A

Extract

42
Q

How long after avulsion is the recall

A

one week

43
Q

How long to splint teeth after avulsion? What kind of splint?

A

Up to 2 weeks (7-10 days)

Flexible splint

  • rigid splints lead to ankylosis
44
Q

How long to splint teeth following alveolar fracture

A

4 months
