trauma Flashcards
crown infarction
incomplete fracture of the enamel without loss of tooth structure
complicated crown fractur
INVOLVES PULP
Ellis class I
only in enamel
ellis class II
enamel and dentin fracture
ellis class III
pulpy pulp
root fractures
involve cementum, dentin and pulp
ellis class VI
apparently your whole root breaks like horizontally
concussion
injury to tooth supporting structures WITH NO ABNORMAL LOOSENING, tooth is tender to percussion
subluxation
injury to tooth supporting structures WITH LOOSENING but NO clinical or radiographic evidence of displacement
intrusive luxation
displacement of tooth deeper into alveolar bone, communition/fracture of alveolar bone
extrusive luxation
partial displacement of tooth out of socket
lateral luxation
displacement in a direction other than axially, fracture of socket
exarticulations
complete avulsion (totally displaced out of socket)
communition of alveolar socket
cracked of socket, associated with intrusive or lateral luxation
a fracture of the alveolar socket wall is confined to…
facial or lingual socket wall
laceration
shallow or deep wound in mucosa resulting form a tear
contusion
bruise, usually not accompanied with a break in mucosa
abrasion
superficial wound produced by rubbing or scraping and leaving a raw, bleeding surface
what percentage of battered children/spouse get facial injuries
50%
predisposing factors to dental trauama
increased overate with protrusion and insufficient closure
tooth injuries TWICE as frequentt in children with protrusive incisors
prevalence of dental trauma
4-14% (probably higher)
are boys or girls more affected by dental truama
boys
what tooth most commonly gets fucked up
anterior teeth, usually single tooth
what type of injury do primary teeth usually get
luxation and/or avulsion
