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.

Follow up: In children, pulp necrosis was usually
diagnosed within 6 months after the injury
(91.9% of all injured teeth) and in virtually all
teeth within one year.
In patients older than 15 years, pulp necrosis
was predominantly diagnosed later than 6
months (61.7% of all cases) or even later than
12 months (40%) after the trauma

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

There is minimal impact from
endodontic treatment. Most
influence is from

•!initial management in order to
maintain vitality of the periodontal ligament fibers

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.

•!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.

•!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:
