AIM of Trauma Management:

•!Maintain, preserve or reinstate the

original dentition

Objective of Trauma Management:

•!Preserve the pulp

•!Preserve the periodontal ligament

•!Maintain aesthetics of the dentition

•!Maintain function of the dentition

•!Ensure comfort of the dentition

Want to avoid treatable pathology that may result in loss of tooth (such as inflammatory resorption) or patient symptoms

such as pulp necrosis or pulpitis.

A parent’s nightmare

Pathology may not be evident early or provide confusing signs and symptoms. May get necrosis

with infection late such as after calcification.

How do we assess and manage?

Every effort is made to preserve the pulp of the immature permanent tooth, or induce

revascularization or regeneration of pulp tissue.

Remember dental trauma can happen any time and any place. The first course of treatment is

prevention.!

Should football players wear custom fitted mouthguards? Results from a group randomised controlled trial

C Finch, R Braham, A McIntosh, P McCrory and R Wolfe

Injury Prevention 2005;11:242-246

• This is the first randomized controlled trail of the

effectiveness of protective equipment in community level

Australian football, and one of a few worldwide in any sport.

• Players who were allocated to the

custom fitted mouthguard study arm had

a significantly lower rate of head and

orofacial injuries than all other players.

Mouthguards in sport activities : history, physical properties and injury prevention effectiveness. Knapik JJ, Marshall SW, Lee RB, Darakjy SS, Jones SB, Mitchener TA,

delaCruz GG, Jones BH. Sports Med. 2007;37(2):117-44

Studies that have examined injuries among mouthguard

users and nonusers are of highly variable methodological quality. However, published research consistently shows that

mouthguards offer significant protection against orofacial

injuries.

Meta-analysis indicates that the overall risk of an orofacial injury is 1.6–1.9 times higher when a mouthguard is not worn,

relative to wearing a mouthguard.

•!Accidents within and around the home were the major sources of injury to the primary dentition

•!Accidents at home and school accounted for most of the

injuries to the permanent dentition.

1. Alveolar changes - Transient marginal breakdown

Following injury to the supporting bone, remodelling

occurs with fabrication of granulation tissue.

This is seen as a widened PDL space. After 2-3 months the periodontium usually reforms

This can also be seen at the apex as transient apical

breakdown (a transient apical radiolucency)

1. Alveolar changes -Permanent marginal breakdown

Following injury to the supporting bone,

remodelling occurs with fabrication of

granulation tissue.

This is seen as a widened PDL space.

In some instances the healing of the bone

does not occur.

This may be due to the degree of trauma,

or presence of infection.

Bony sequestrum may even occur.

May be seen after lateral luxations,

avulsion, intrusion, alveolar fracture or jaw

each meal.

•!Use a chlorhexidine (0.1%) mouth rinse twice a day for 1 week.

Follow up as for all trauma:

Any symptoms

Clinical signs

•! Sinus tract stoma or swelling

•! Gingivitis

•! Pocket depth

•! Recession

•! Tooth Colour

•! Loosening

•! Tenderness to palpation

•! Tenderness to percussion

•! Thermal test (sensibility, sensitivity)

•!Radiograph-mm dislocation, pulp calcification, continued root

development, marginal bone loss, periradicular radiolucency, resorption.!

In Summary when do I perform endodontic treatment? IADT 2011 suggest 2 signs and symptoms are required to

suggest pulpal infection.

When I think the pulp is infected (not just necrotic)

1.!Radiographic: •!Periapical lesion not resolve or increasing

•!Size of pulp chamber (internal resorption)

•!Sign of external inflammatory resorption

•!Pulp calcification is a sign of pulp vitality

•!Continued root development

2 !Clinical:

•!Response to pulp testing: calcification vs necrosis (but is

it infected?) vs vascular intact •!Colour (calcification vs necrosis vs transient hyperaemia)

•!Sinus tract stoma

•!Prolonged TTP

3. Tenderness to percussion

Andreasen found that the only sign significantly

related to pulp necrosis was tenderness to

pecussion following tooth luxation. (Andreasen et al;

Textbook and colour Atlas of Traumatic Injuries to the teeth – 4th Edition p 378 from Andreasen FM,

Endod Dent Traumatol 1989;5:111-31)

4. Coronal discolouration

Andreasen states that grey colour changes can be

seen in the crown even 2 to 3 weeks after trauma.

This may be accompanied by radiographic periapical

radiolucency. (Andreasen et al; Textbook and colour Atlas of Traumatic Injuries to the teeth – 4th Edition p

378 from Andreasen FM, Endod Dent Traumatol

1989;5:111-31).

But even colour changes may be transitory and as with apical radiolucency may resolve and reverse

within 1 year. (Andreasen et al; Textbook and colour

Atlas of Traumatic Injuries to the teeth – 4th Edition p

378 from Andreasen FM, Endod Dent Traumatol 1989;5:199 and 201).

"!

4. Coronal discolouration

Grey coronal colour change is often, not always,

related to pulpal haemorrhage or pulp necrosis.

Yellow coronal colour change is related to pulpal calcification.

Clinically Heithersay feels that if discoloration begins

it rarely reverses (ADJ 2007). If there is no change in

3 months I begin RCT.

When do I Splint teeth?""

Reason for splinting:"1.! Aid repair"

2.! Comfort-loose, TTP"

!

!

•!The prognosis for the healing outcome is more dependent on the type of injury rather

than the effect of the splinting.

•!the use of cap splints and orthodontic

bands were associated with a greater frequency of pulp necrosis (31, 38) and pulp

canal obliteration (45) when compared with

acid etch resin splints and no splinting.

•!the majority of the selected studies suggested that an extended fixation period is

not an indicator for a poor healing outcome.

IADT 2011 Guidelines for intrusion:

Incomplete root formation:

•! Allow eruption without intervention

•! If no movement in 3 weeks initiate orthodontic

repositioning •! If tooth is intruded more than 7mm, reposition surgically or

orthodontically.

Teeth with complete root formation:

Allow eruption without intervention if intruded less that 3mm.

If no movement in 3 weeks initiate orthodontic or surgical repositioning to limit chance of ankylosis.

If tooth is intruded more than 7mm, reposition surgically or

orthodontically.

Teeth with closed apices will require RCT – commence 2 to 3 weeks after repositioning.

Once an intruded tooth has been repositioned surgically or

orthodontically – stabilize for 4 to 6 weeks.

Summary of the three methods are only partly evidence based. (From www.dentaltraumaguide.org)

Spontaneous eruption

This is the treatment of choice for deciduous/primary teeth

and for permanent teeth with incomplete root formation.

This treatment has been shown to lead to significantly fewer healing complications than orthodontic and surgical

repositioning. If no movement is noted within 3 weeks,

recommend rapid orthodontic repositioning.

Orthodontic repositioning

This treatment may be preferred for patients with delayed treatment. This allows repair of marginal bone in the socket

along with the slow repositioning of the tooth.

Surgical repositioning

This treatment technique is preferable in acute phase. Intrusion with major dislocation of the tooth (approximately

more than half a crown length) may be an indication for

surgical repositioning.

!

Root canal treatment should be considered in all cases with completed root formation where the

chance of pulp revascularization is unlikely.

Endodontic therapy should preferably be initiated

within 3-4 weeks post-trauma.

If pulp capping is not successful try

revascularization rather

than calcium hyrdoxide

or MTA apexification.

This is different to Follow-up procedures for avulsed permanent teeth:

•!If root canal treatment is indicated (teeth with closed apex),

the ideal time to begin treatment is 7- 10 days postreplant.

•!Calcium hydroxide is recommended for intra canal medication for up to one month followed by root canal filling

with an acceptable material.

•!An exception is a tooth that has been dry for more than 60

minutes before replantation – in such cases the root canal treatment may be done prior to replantation.

•!In teeth with open apices, that have been replanted

immediately or kept in appropriate storage media, pulp revascularization is possible. Root canal treatment should be

avoided unless there is clinical and radiographic evidence of

pulp necrosis.

21/03/12!

•!In cases of replanted teeth where endodontic treatment is not yet indicated teeth should be

monitored by frequent controls during the first year

(once a week during the first month, 3, 6, and 12

months) and then yearly thereafter.

•!Clinical and radiographic examination will provide

information to determine outcome.

SUMMARY: My preference is to give teeth and pulps the benefit of the doubt and treat as necessary as we can induce

periapical lesions to heal:
