Dento-alveolar trauma:
In children is distressing for both child and
parent.
Often difficult for the dentis.
It is important that the dentist (all members
of the dental team) are well prepared to
meet the many complex and challenging
problems in the care of dental
emergencies.
Is one of the most common reason young
children to visit a pediatric dentist.
This concerns especially for cases whit little
children \toddler\.

History
When the patient is received for treatment, the first step is to get an initial impression of the extent of the injury.
Has a tooth been knocked out?
Is the patient’s general condition affected?
Is there a need for immediate medical care?
![Page 4: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/4.jpg)
History of
the
Dental Injury
Three important questions are asked in gathering the dental history:
When?
Where?
How did the accident occur?
![Page 5: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/5.jpg)
Dental history
When did the injury occur?
The time interval between injury and treatment can influence both the treatment procedure and the expected outcome.
Optimal repositioning of an extruded permanent tooth is difficult if treatment is delayed.
The time factor is also very critical for the prognosis of replanted teeth.
![Page 6: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/6.jpg)
Dental
history
Where did the injury occur ?
This information is important for insurance and social security purposes.
The place of accident also provides information on the need for tetanus prophylaxis in replantation cases.
![Page 7: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/7.jpg)
Dental history
How did the injury occur?
The nature of the blow may provide
information about the type of injury,
which can be expected.
When a blow hits the chin, the
mandibular arch is forced against
the maxillary arch.
As possible resulting injuries:
Jaw fracture
Сrown-root fracture in the
premolar or molar regions
![Page 8: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/8.jpg)
Dental history
Was there a period of unconsciousness?
If so, for how long?
Is there а headache? Amnesia? Nausea? Vomiting?
Excitation or difficulties in focusing the eyes?
These are all signs of brain concussion and require medical attention.
![Page 9: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/9.jpg)
Head injury
Between 25% and 50% of all
accidents in children up to 14 years
involve the head.
If there is any suggestion that a
head injury has been sustained, the
child should be immediately
medically assessed.
![Page 10: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/10.jpg)
Signs of closed head injury
● Altered or loss of consciousness.
● Bleeding from the head or ears.
● Disorientation.
● Prolonged headache.
● Nausea, vomiting, amnesia.
● Altered vision or unilateral
dilated pupil.
● Seizures or convulsions.
● Speech difficulties.

Dental history
Is there any disturbance in the bite?
Disturbance in the occlusion can imply:
luxation injury
alveolar fracture
jaw fracture or luxation
or fracture of the temporomandibular
joint.
Limitations of mandibular movement or
mandibular deviation on opening or
closing the mouth indicate that the jaw
might be fractured.
![Page 12: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/12.jpg)
Medical history
A short medical history should
reveal
Possible allergies
Blood disorders – very important if
soft tissues are lacerated or teeth
are to be extracted
Congenital heart disease
Other information about
conditions that could interfere
with treatment.
![Page 13: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/13.jpg)
Clinical
examination
![Page 14: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/14.jpg)
Extraoral
examination
The facial skeleton should be palpated to determinediscontinuities of facial bones.
Extraoral wounds and bruises should be recorded.
Deep lip wounds are examined closely with respect to tooth fragments or other foreign bodies.
![Page 15: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/15.jpg)
Extraoral examination
The temporomandibular joints should be palpated, and any swelling, clicking, or crepitus should be noted.
Mandibular function in all excursive movements should be checked.
Any stiffness or pain in the child's neck necessitates immediate referral to a physician to rule out cervical spine injury.
![Page 16: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/16.jpg)
Intraoral examination
All soft tissues should be examined and any injuries
recorded.
The presence of foreign matter in lacerations of the
lips and cheeks, such as tooth fragments or soil,
should be identified.
Removal at the initial appointment will eliminate
chronic infection and disfiguring fibrosis.
![Page 17: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/17.jpg)
Intraoral examination
It is important to examine all teeth within a
traumatized area;
In close bite situations;
Also teeth in the opposite jaw;
Each tooth in the mouth should be examined
Particular note is taken of the following
factors:
![Page 18: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/18.jpg)
Intraoral
examination
Displacement.
The direction as well as the extent (in mm) of displacement should be recorded.
Minor displacement can be difficult to detect.
In such cases it is helpful to examine the occlusion as well as radiographs taken at various angulations.
![Page 19: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/19.jpg)
Intraoral examination
Mobility
The degree of mobility is assessed
in a horizontal and vertical
direction
keeping in mind that immature
permanent teeth and primary
teeth undergoing root
resorption have quite extensive
physiologic mobility.
When several teeth move
together en bloc, a fracture of
the alveolar process is suspected.
![Page 20: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/20.jpg)
Intraoral examination
Reaction to percussion.
The handle of a mouth mirror is
tapped gently against the
teeth in a horizontal and
vertical direction.
Tenderness to percussion
indicates damage to the
periodontal ligament.
A high metallic tone implies
that the injured tooth is locked
in bone.
![Page 21: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/21.jpg)
Intraoral
examination
Color of the tooth
Discoloration may appear
almost immediately after the
injury.
Special attention should be
paid to the palatal surface in
the gingival third of the crown.
![Page 22: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/22.jpg)
Intraoral examination
Reaction to sensibility tests
It is usually not possible to obtain reliable information from a young, frightened child.
In the permanent dentition electrometric sensibility testing should be performed whenever possible.
It gives important information about the neurovascular supply to the pulp.
Provides a baseline value for comparison at follow-up examination.
![Page 23: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/23.jpg)
Reaction to sensibility tests
The contralateral uninjured tooth or another comparable tooth serves as a control.
The most reliable response is obtained when the electrode is placed upon the incisal edge.
It is important to explain the purpose of the test and the type of reaction to be expected.
![Page 24: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/24.jpg)
Radiographic
examination
Is mandatory in order to get an
impression:
Of the injury to the supporting
tissues
The stage of root development
In the case of primary tooth
injuries, the relation to
permanent successors
The injury site should be viewed
from different angulations.
![Page 25: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/25.jpg)
Diagnosis
A diagnosis is based on
information from the
clinical and radiographic
examination.
The injury is classified as a
guide to the treatment
required.
We use the classification,
recommended by the
World Health Organization
(WHO).

Injuries to primary teeth. Clinical features, diagnosis and treatment
![Page 31: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/31.jpg)
Epidemiology in primary dentition:
At 5 years of age
11 – 30 % of children suffer trauma to
primary dentition (31 – 40 % of boys and
16 – 30 % of girls)
The incidence of injuries to primary
teeth increases from 1 year of age –
peak incidence is at 2 – 4 years
Most traumas involve children younger
than 4 years of age.
In preschool children, trauma in
boys is more common than in girls.
![Page 32: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/32.jpg)
Epidemiology:
Depending on the affected teeth:
The most frequently injured teeth in the primary
dentition are the maxillary incisors.
Primary molars are rarely injured - when injury
occurs it is usually due to indirect trauma
blows to the underside of the chin causing
the mandible to close forcefully against the
maxilla.
![Page 33: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/33.jpg)
Epidemiology:
Depending on the kind of injury:
In the primary dentition luxation injuries are
more common than fractures due:
to the spongy nature of the bone in young children
to the lower root/crown ratio in comparison with
that of permanent teeth.
Concussion and subluxation – are the next
most injuries
![Page 34: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/34.jpg)
Aetiology: In a young child learning to walk and to
run, muscle coordination and judgmentare incompletely developed and fallinginjuries frequently occur.
Predisposing factors:
Malocclusion – protrusion
Most injuries are caused by falls and play accidents.
Another major cause of dental injuries in young children is automobile accidents.
Child abuse is serious cause of dental injuries to young children.
- Physical abuse. - Emotional abuse.
- Neglect. - Sexual abuse.
![Page 35: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/35.jpg)
Important!
The permanent incisor is located palatally during its early development and in close proximity to the apex of the primary incisor.
With any injury to primary teeth, the dentist must always be aware of possible damage to the underlying permanent teeth.
A primary incisor should always be removed if its maintenance will jeopardize the developing tooth bud.
![Page 36: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/36.jpg)
Important!
A traumatized, retained primary tooth should
be assessed regularly for clinical and
radiographic sings of pulpal or periodontal
complications.
Every 3-4 months – for the 1. year
Then annually until tooth exfoliation
Soft tissue injuries should be assessed weekly
until healed

Concussion – description:
An injury to the tooth-supporting structures:
without increased mobility
tooth is not displaced
but with pain to percussion
without gingival bleeding.
![Page 39: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/39.jpg)
Concussion – etiology:
The neurovascular supply is usually intact
In a few areas bleeding edema
In most areas the periodontal ligament is without
damage
No damage to the follicle or permanent tooth
germ
![Page 40: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/40.jpg)
Diagnostic signs
➢ The signs of concussion are transient. It is not possible to
diagnose concussion if the examination is done several days after
injury.
Visual signs
Percussion test
Mobility test
Pulp sensibility test
Radiographic findings
Radiographs
recommended
Not displaced.
Tender to touch or tapping.
No increased mobility.
Not reliable in primary teeth. Inconsistent results
No radiographic abnormalities. Normal
periodontal space.
An occlusal exposure is recommended in order
to screen for possible signs of displacement or
the presence of a root fracture. The radiograph
can be used as a reference point in case of
future complications.

Only observation is needed
Clinical control at 1 week, 6-8 weeks.
![Page 42: Dento- alveolar...2020/03/23 · Dento-alveolar trauma: In children is distressing for both child and parent. Often difficult for the dentis. It is important that the dentist (all](https://reader036.vdocuments.mx/reader036/viewer/2022081402/6072226bd0330851e876ac8b/html5/thumbnails/42.jpg)
PATIENT
INSTRUCTIONS
Soft food for 1 week.
as far as possible - children do not bite with teeth
Good oral hygiene.
Brush with a soft brush after every meal and apply chlorhexidine 0.1% topically to the affected area with cotton swabs twice a day for one week.
This is beneficial to prevent accumulation of plaque and debris

PATIENT
INSTRUCTIONS
Parents should be further advised about possible complications that may occur, like:
swelling,
dark discoloration of the crown,
increased mobility or fistula.
Children may not complain about pain;
however, infection may be present and parents should watch for signs of swelling of the gums and bring the child in for treatment.

Extrusion
Partial displacement of the tooth out of
its socket
An injury to the tooth characterized by
partial or total separation of the

loosening and displacement of the
tooth.
The alveolar socket bone remains
intact.
In addition to axial displacement, the
tooth usually will have some protrusive
or retrusive orientation.

Treatment
The treatment choice should be based on the:
degree of displacement
mobility
root formation
the ability of the child to cope with the emergency situation.
For minor extrusion (< 3 mm) in an immature developing tooth
either careful reposition the tooth
or leave the tooth for spontaneous alignment.
Extraction is the treatment of choice for severe extrusion in a fully formed primary tooth.

Diagnostic signs Lateral luxations are complicated by fracture of either
the labial or the palatal/lingual alveolar bone and a
compression zone in the cervical and sometimes the
apical area.
If both sides of the alveolar socket have been
fractured, the injury should be classified as an alveolar
fracture (alveolar fractures rarely affect only a single
tooth).
In most cases of lateral luxation the apex of the tooth
has been forced into the bone by the displacement,
and the tooth is frequently non-mobile.

Radiographic findings
Radiographs recommended
Displaced, usually in a palatal/lingual or labial direction
Usually gives a high metallic (ankylotic) sound
Usually non-mobile.
Not reliable in primary teeth. Inconsistent results
Increased periodontal ligament space apically is best seen on the occlusal exposure
An occlusal exposure can sometimes show the position of the displaced tooth and its relation to the permanent successor.

Treatment
• If there is no occlusal interference, as is often the case in anterior open bites, the tooth should be allowed to reposition spontaneously.
Spontaneous repositioning
• Clinical control after 1 and 2-3 weeks.
• Clinical and radiographic control at 6-8 weeks and 1 year.
• Once per year until physical exfoliation of the tooth

Treatment
Repositioning
When there is occlusal interference local anesthesia
should be applied where after the tooth should be
repositioned by gentle combined labial and palatal
pressure.
Follow-up
Clinical control after 1 and 2-3 weeks.
Clinical and radiographic control at 6-8 weeks and 1
year.
Once per year until physical exfoliation of the tooth

Treatment
Extraction (protrusion)
For teeth with severe
displacement in a labial direction,
extraction is the treatment of
choice.
Extraction is indicated in these
cases because of the collision
between the primary tooth and
the permanent tooth germ.

Diagnostic signs
The tooth is displaced axially into the alveolar
bone and frequently penetrating the labial bone
plate where it can be palpated.
The tooth may disappear completely in the tissues
resembling avulsion and root fracture with
complete extrusion of the coronal fragment.
In this case diagnosis is based on an occlusal
radiograph.
Penetration of the tooth into the nasal cavity can
be diagnosed by bleeding from the nose or simple
observation of the nostril.

Radiographic findings
Usually give a high metallic (ankylotic) sound; in severe intrusion cases - not always possible to perform.
The tooth is non-mobile.
Not reliable in primary teeth.
When the apex is displaced toward or through the labial bone plate the apical tip can be visualized and appears shorter than the unaffected contralateral tooth.When the apex is displaced toward the permanent tooth germ, the apical tip cannot be visualized, and the tooth appears elongated.

findings
Radiographs
recommended
The tooth is removed from its socket.
The alveolar socket will be empty. If the
avulsed tooth is not present a
radiographic examination is essential to
ensure that the missing tooth is not
intruded.
An occlusal exposure is recommended
in order to screen for the presence of
root fragments and to make sure that
the missing tooth is not intruded.

TreatmentReplantation is contraindicated
In the initial examination all avulsed teeth are accounted for.
If not, it is recommended to make a radiographic examination in order to ensure that the missing tooth is not a case of complete intrusion or root fracture with loss of the coronal fragment.
If the avulsed tooth has not been found refer the child to the pediatrician to exclude aspiration.

findings - two treatment
scenarios may be considered.
• If the fracture involves only a small part of the root
• The stable fragment is large enough to allow coronal restoration,
• Remove the mobile fragment.
Fragment removal only
• Extraction in all other instances.Extraction

Alveolar fracture
A fracture of the alveolar process
which may or may not involve the
alveolar bone socket.
Teeth associated with alveolar
fractures are characterized by
mobility of the alveolar process;
several teeth typically will move as a
unit when mobility is checked.
Occlusal interference is often
present.
