Paeds-trauma Flashcards
What is a laceration?
A soft tissue tear.
Why do you check if a pateint can open their mouth?
As if the patient had any jaw fractures, opening their mouth would be difficult.
How does trauma affect the patient’s occlusion?
It could prevent the teeth occluding together by propping them open or being the first thing that touches them when they touch.
Where do you check for foreign bodies after trauma?
Lodged in soft tissues
Penetrating wounds.
What does tooth mobility indicate?
Tooth displacement
Root fracture
Bone fracture (if several teeth on a segment are mobile)
How long does trauma review continue for after injury?
Sensibility tests are continued for at least 2 years after injury.
Name this fracture?

Enamel fracture
Name this fracture?

Enamel dentinal fracture.
Name this fracture

Enamel dentine pulp fracture.
Name this fracture & explain how you would further describe this?

This is a root fracture. It is further described by the 1/3 of the root that has fractured:
apical 1/3
middle 1/3
coronal 1/3
Compare these two fractures

On the left- UNcomplicated crown root fracture- the fracture is affecting enamel, dentine and into the root but is not affecting the pulp.
R- complicated crown root fracture- The pulp is also affected by the fracture.

Why would a tetanus prophyaxis be used as an emergency treatment for trauma?
In case bacteria would get into the wound.
Compare apexigensis with apexification?
Apexigenesis- when the tooth growth naturally continues after damages.
Apexification- when an intervention is needed to to provide an apex for the tooth.
When should you follow up fractures?
For enamel or enamel dentine
6-8 weeks and 1 year.
Enamel dentine pulp
6-8 weeks. 3 months. 6 months. 1 year.
Crown root fractures
1 week. 6-8 weeks. 3 months. 6 months. 1 year. yearly for 5 years
In what ways can we manage an enamel fracture?
Bond the fragment back to the tooth
Grind the sharp edges
Replace the fracture with a little bit of composite.
How do we manage an enamel dentine fracture?
We bond the fragment to the tooth.
Place a composite bandage.
Where would you look for a lost fragment?
On the ground
In soft tissues
In the lungs (Especially if patient is coughing or wheezing)
It may have been swallowed.
How do we check for root development in a radiograph?
We check for:
- width of the canal
- Length of the canal (if the root continues to grow it is still alive)
- Internal or external resorption.
- periapical pathologies.
Why is there more chance of damage with trauma of a mature tooth than an immature tooth?
A mature tooth has a small apex. The smaller apex means it is more likely for the nerves to be ripped and torn causing pulp death.
This is in contrast to a wider apex (immature tooth)
In an enamel dentine pulp fracture-
The pulp exposure is <1mm and <24 hours old.
How would you treat this?
Direct pulp cap.
- LA
- Isolate tooth with rubber dam
- Clean exposed area with saline
- Disinfect with sodium hypochlorite
- Place calcium hydroxide over the exposed site
- Seal the exposed resin with GIC or composite resin
- Restore tooth with composite.
In an enamel dentine pulp fracture-
The pulp exposure is bigger than 1mm. How do you treat this?
Partial pulpotomy.
- LA
- Isolate with rubber dam
- Clean exposed area with saline
- Disinfect with sodium hypochlorite
- Remove pulp to a depth and width of 1-2mm using a round diamond bur
- Place a saline moistened cotton pellet on the pulp & check haemostasis
- Apply calcium hydroxide
- Seal exposed dentine with GIC or composite.
- Restore with composite.
In an enamel dentine pulp fracture-
The pulp exposure is more than 24 hours old. How do you treat this?
Partial pulpotomy.
- LA
- Isolate with rubber dam
- Clean exposed area with saline
- Disinfect with sodium hypochlorite
- Remove pulp to a depth and width of 1-2mm using a round diamond bur
- Place a saline moistened cotton pellet on the pulp & check haemostasis
- Apply calcium hydroxide
- Seal exposed dentine with GIC or composite.
- Restore with composite.
In an enamel dentine pulp fracture-
You have started treating the pulp, but cannot arrest the bleeding. How do you manage this?
A full coronal pulpotomy.
- Remove all of the coronal pulp
- Place calcium hydroxide in the pulp chamber. (Thin layer so we have space for the vitrebond- prevents the dycal washing out)
- Seal with GIC lining & a quality coronal restoration.
Compare a concussion injury to a subluxation injury.
including review and treatment.
concussion- injury without increased mobility.
Subluxation- injury with increased mobility
Concussion review- 4 week,1y
Subluxation review- 2w,12w,6m,1y
Treatment for concussion- occlusal relief
Treatment for subluxation- a 2 week flexible splint
