Dental Trauma Flashcards
define Dental Trauma
the impact injury to the teeth and/or other hard and soft tissues
How can Dental Trauma have mental health impacts? (2)
social judgements
appearance
What may the simple Aetiology of Dental Trauma be?
falling over
What Classification is most Commonly Used?
Andreasen’s Classification
What are the 4 Hard Tissues?
enamel, dentine, pulp, root
What are the Types of Hard Tissue Dental Trauma? (6)
Enamel Infraction
Enamel Fracture
Enamel-Dentine Fracture
Enamel-Dentine-Pulp Fracture
Crown-Root Fracture
Root Fractures
What is Enamel Infraction?
enamel is fractures but no tooth surface loss
- looks like cracks and lines
- can use transillumination to diagnose
What is an Enamel Fracture?
only enamel is fractured, there is tooth surface loss
What is an Enamel-Dentine Fracture?
only enamel and dentine is fractures, with tooth surface loss
What is an Enamel-Dentine-Pulp Fracture and how to Treat?
a complicated crown fracture, exposing the pulp
- pulp cap
- partial pulpotomy
What are Crown-Root Fractures?
involves enamel, dentine and maybe pulp
fracture line extends below gingival crevice and alveolar bone margin
- crown fragment may be attached
What is a Root Fracture?
the root has a fracture it involves cementum, dentine and pulp
Which Soft Tissue can Dental Trauma Mostly Affect?
PDL
What are the 6 Types of Soft Tissue Dental Traumas? SpECIAL
- concussion
- sublaxation
- extrusion
- lateral luxation
- avulsion
- intrusion
What is Concussion Dental Trauma? Describe it.
injury of tooth support structure
with reaction to horizontal or vertical percussion
- PDL fibres = intact
- not displaced, not mobile
What is Subluxation Dental Trauma? Describe it.
injury of periodontal tissue
- PDL fibres tear
- not displaced
- increased mobility
- gingival haemorrhage
sublaxation = partial dislocation
What is Extrusion Dental Trauma? Describe it.
extrusion - forced pushing out
- partial displacement of tooth out of alveolar socket
- PDL fibres rupture and tear
- very mobile
- displaced
- gingival haemorrhage
- clinically elongated
What is Lateral Luxation Dental Trauma? Describe it.
tooth is displaced alongside fracture of alveolar bone
- PDL ruptures and compressed
- not as mobile as it locks into bone
- very displaced
- gingival haemorrhage
- high tone on percussion
- neurovascular supply disruption
What is Avulsion Dental Trauma? Describe it.
complete displacement of tooth out of socket
- replant asap or place in milk
What is Intrusion Dental Trauma? Describe it.
tooth is displaced into the alveolar bone, with fracture of the alveolar socket
- displaced vertically upwards
- periodontal structures crushed
- neurovascular bundle disrupted
- may become necrotic
