Dental Trauma II Flashcards
what does asymptomatic discolouration to a primary tooth post trauma indicate
tooth can be vital or non vital
immediate grey discolouration means tooth may maintain vitality
opaque/yellow discolouration indicates pulp obliteration
no tx required
what does symptomatic discolouration of a primary tooth post trauma indicate
tooth non vital
may indicate infection - assess for sinus, gingival swelling and abscess
may be evidence of periapical pathology on radiograph
tx = extraction or endo
what complication might delayed exfoliation of a primary tooth post trauma result in
consequences to the permanent occlusion
what age does primary tooth trauma pose the biggest risk to complications of permanent successors
younger the child = increased risk of complications
what injury poses the biggest risk of complications/ disturbance to developing successor
intrusion
what enamel defects may be seen on a permanent tooth that was a successor to a primary tooth that experienced trauma
enamel hypomineralisation - normal thickness and amount but decreased mineralisation
enamel hypoplasia - normal mineralisation but decreased thickness and amount
what enamel defects may be seen on a permanent tooth that was a successor to a primary tooth that experienced trauma
enamel hypomineralisation - normal thickness and amount but decreased mineralisation
enamel hypoplasia - normal mineralisation but decreased thickness and amount
what may happen to the root of a a permanent tooth that was a successor to a primary tooth that experienced trauma
dilaceration - abrupt deviation from long axis (sharp bend)
why might a permanent tooth that was a successor to a primary tooth that experienced trauma experience delayed eruption
due to thickened mucosa around trauma site
if delayed more than 6 months after contralateral tooth eruption take a radiograph to investigate position
what injury might see arrested development of a permanent tooth that was a successor to a primary tooth that experienced trauma
intrusion
what 8 things should be included on a trauma stamp for a permanent tooth that has experienced trauma
sinus: +/-
colour
TTP
mobility
EPT
ECL
percussion note
radiograph
what else can be done to aid transillumination when looking for surface fractures
tactile test with probe
What should immediate treatment of a permanent crown fracture aim to do and how is this done
aim is to retain vitality
any exposed pulp should be treated
exposed dentine covered with dentine bandage
return any displaced teeth and imobilise them with a splint
consider tetanus and antibiotic prophylaxis
how long should sensibility testing be continued for on a permanent tooth that has experienced trauma
at least 2 years
permanent tooth: enamel fracture
treatment and follow up
either bond fragment back to tooth or remove sharp edges
take 2 periapicals to rule out root fracture or luxation
follow up: 6-8 weks, 6 months and 1 year
