Q

Tx of extrusion in permanent tooth?

A

Give LA

Clean exposed root surface with saline

Reposition tooth by gentle reinsertion into the socket

Stabilise for 2 weeks with a splint or 6 weeks if marginal bone fracture

Monitor pulpal condition for vitality and root resorption

If pulpal necrosis / infection, carry out appropriate endodontic tx for root maturity

Q

Tx of lateral luxation in permanent tooth?

A

All teeth:
- apply LA

Q

Tx of intrusion in permanent tooth with immature root?

A
  • allow spontaneous repositioning
  • if no eruption within 4 weeks, commence orthodontic repositioning
  • monitor pulpal status
  • spontaneous revascularisation may occur, if not then RCT tooth ASAP

Q

Tx of intrusion in permanent tooth with mature apex?

A

Allow spontaneous repositioning if tooth intruded 3>mm
- if no re-eruption within 4 weeks, surgically reposition and splint for 2 weeks, or orthodontically reposition

If intrusion is 3-7mm, right to surgical or orthodontic repositioning

Beyond 7mm, reposition surgically

RCT within 2 weeks or as soon as position of tooth allows

A

Leave in place and apply LA
- clean area with saline
- verify normal tooth position
- splint for 2 weeks
- systemic antibiotics
- tetanus jab if not covered
- RCT if pulp does not revascularize

Q

Tx of avulsed permanent tooth with open apex and EOT >60 mins?

A
  • clean root surface and apical foramen with saline and place in storage medium while taking history
  • give LA no vasoconstrictor
  • examine socket for fracture and irrigate socket with saline
  • replant tooth and confirm correct position
  • flexible splint for 2 weeks
  • systemic antibiotics
  • tetanus jab if not covered
  • treat root surface with 2% sodium fluoride solution for 20 mins

Q

Why does delayed replantation have a poor prognosis?

What are the aims of tx in delayed replantation?

Likely outcome?

A

PDL will be necrotic and cannot be expected to heal

  • goal to restore dentition for aesthetic, functional and psychological reasons
  • to maintain alveolar contour

Ankylosis and resorption of root

Q

Tx of avulsion of mature apex tooth that has been replanted prior to presenting?

A

Leave tooth in place
- clean area with saline
- LA no vasoconstrictor
- reposition tooth within 48 hours of trauma if placed wrong into socket
- confirm position radiographically
- 2 week splint
- systemic antibiotics
- tetanus booster if not covered
- RCT 2 weeks

  • LA no vasoconstrictor
  • check socket for fracture and irrigate socket with saline
  • replant tooth and confirm position
  • splint for 2 weeks
  • systemic antibiotics
  • tetanus booster if not covered

Q

Tx of avulsed permanent tooth with mature apex where EOT >60 mins?

A

Clean root surface and apical foramen with saline
- place tooth in storage medium while taking history / exam
- LA no vaso
- examine socket for fracture, irrigate socket with saline
- replant tooth and verify correct position
- 2 week splint
- systemic antibiotics
- tetanus booster if not covered
- RCT 2 weeks

2% sodium fluoride solution for 20 mins - slow down osseous replacement

Q

Tx of enamel fracture in permanent tooth?

A

Radiographic examination to rule out other injury
- 3 views

Smooth sharp edges

  • etch and bond
  • composite

Or re-bond lost tooth fragment

Q

Tx of ED fracture in permanent tooth?

A

Clean area with saline
- disinfect dentine with chlorhexadine

  • if fragment available, but is dry, rehydrate in saline for 20 mins before bonding back to tooth

No fragment?
- account for it - soft tissues / chest X-ray
- consider cap / lining if close to pulp
- cover exposed dentine with GIC
- definitive restoration

17
Q

Tx of EDP fracture in permanent tooth?

A

Preserve vitality!

  • pulp cap or partial pulpotomy advised in both mature and immature apex
  • if fragment available, bond back to tooth

RCT if a post is to be placed or there is an associated luxation injury with displacement

18
Q

Tx of crown root fracture without pulpal involvement in a permanent tooth

A
  • localise fracture line
  • stabilise loose fragment to adjacent teeth as emergency tx while definitive plan made

Options for definitive

Fragment removal only
- and restoration of exposed dentine

Fragment removal and gingivectomy

Ortho extrusion of apical fragment

Surgical extrusion of apical fragment more coronally

Coronectomy for later implant placement to retain bone levels

Extraction and delayed fixed pros

19
Q

Tx of crown root fracture with pulpal involvement in permanent tooth

A

Emergency tx includes
- localise fracture line with radiographs
- stabilise loose fragments to adjacent teeth

In open apex
- pulp cap or partial pulpotomy

In closed apex
- extirpate pulp

Cover dentine with GIC and composite restoration

Refer for definitive tx
- same as CRF with no pulpal involvement

20
Q

Tx of root fracture in permanent tooth?

A

Radiographic examination with 2 exposures

(See avulsion tx if coronal fragment has been avulsed out socket)

  • rinse exposed root surface with saline
  • reposition coronal segment and check position radiographically
  • stabilise with splint for 4 weeks
  • monitor healing for 1 year to determine pulpal status and commence RCT if indicated - up to fracture line

If fracture line is above alveolar crest
- remove coronal segment
- RCT and post and core

21
Q

Tx of alveolar fracture in permanent tooth dentition?

A

LA
- manual repositioning
- clean area with chlorhexadine
- splint 4 weeks
- monitor pulp and commence RCT if indicated
