what would a patient with orbitozygomatic fracture present with
lacerations
nasal bleeding/ deviation/ patency
facial asymmetry
limited mandibular movement
how would you examine a patient for orbitozygomatic fracture
palpation of zygoma bilaterally
examine sensation of infra-orbital region - upper lip, lateral nose and lower eyelid
eye exam - pupillary reaction to light, ask if double vision, eyeball mobility assessment
how would you manage a patient with orbitozygomatic fracture in practice
urgent phone call to OMFS at A&E for urgent referral
surgical management - ORIF if symptomatic (diplopia/asymmetry/enophthalmos)
conservative management - if displaced, asymptomatic or more than 1 month old
how would you assess a patient for XLA who is taking warfarin
ask about INR level
ask if pt knows their INR
ask when INR was last taken
ask to see patient’s INR book
ask if INR is stable
how would you tell a patient in pain that is taking warfarin that the tooth cannot be XLA’s today
due to high risk of bleeding because of your medication (warfarin) your INR values are above the recommended level for safe extractions
how long before an extraction should a patient taking warfarin’s INR levels be checked
ideally within 24 hours, can be 72 hours if stable
stable = INR < 4 for last 3 months
what questions are asked on a BBV screen after sharps injury
have you ever been diagnosed with HIV/ hep B/C
have you ever injected drugs
have you ever had sex with another man
have you had sex with someone outside of europe, canada, USA, australia or New Zealand
have you had a piercing or tattoo done by unlicensed artist in UK or other country
what type of drug is alendronic acid
bisphosphonate
what is the action of bisphosphonate drugs
they reduce the turnover of bone
they accumulate in sites of high bone turnover
what is the relevance of bisphosphonates to dentistry (4)
risk of poor wound healing following XLA
need to remove any teeth of poor prognosis prior to starting bisphosphonates
important to prevent tooth loss in future
reduced turnover of bone and reduced vascularity can lead to death of bone - osteonecrosis - specifically MRONJ
what are the 6 handpiece safety checks
back cap checked - grip and turn anticlockwise
bur security checked - suitable force applied to remove bur
bur rotated laterally with fingers - attempts to spin but
attempts to move bur laterally - pushes bur from side to side
tension applied to handpiece when fitted to coupling
handpiece sound tested whilst running - run for 5 seconds at least
how would you treat an enamel dentine fracture with pulp exposure in a tooth with immature apex
pulpotomy
LA
rubber dam
remove enamel and dentine covering pulp chamber - remove coronal pulp
irrigate with saline
get bleeding to stop with cotton wool soaked saline
place MTA or ZOE
place composite restoration
what is the aim of pulpotomy
partial removal of pulp
aim to keep undamaged pulp tissue alive
so the tooth stays alive and continues to grow
what tests are required before pulpotomy
sensibility - test the affected tooth and adjacent teeth
this is so long term monitoring can occur
what is the SPIKES model
setting - sit down at level with patient
perception - is pt aware of what is going to be discussed
information - inform pt you have results
knowledge - give a warning phrase, give them the information and let it sink in
empathy - ‘i am deeply sorry to break this to you’
summary - repeat news

how is fluoride overdose treated
5mg/kg - milk
5-15mg/kg - ipecac syrup, milk, possible referral
more than 15mg/kg - hospital referral

fluids from nose
speech and signing of nasal quality
problems playing wind instruments
problems smoking or using a straw
bad taste
sinusitis type symptoms
what is OAC
an acute communication between maxillary air sinus and oral cavity
what is OAF
chronic communication between maxillary sinus and oral cavity which has healed by epithelialising forming a sinus and a permanent communication
how is an OAF treated
excise sinus tract/ fistula - removing epithelium
buccal advancement flap
amoxicilling 500mg TID 7 days
post operative instructions following OAF diagnosis
avoid blowing nose or stifiling sneeze by pinching nose
steam or menthol inhalations
avoid using straw
refrain from smoking
what is primary herpetic gingivostomatitis
contagious primary infection caused by herpes simplex virus
self limiting - disappears in 7-10 days
most often occurs in small children and usually first exposure child has to herpes virus
how does primary herpetic gingivostomatitis present
blisters on tongue, cheeks, gum, lips and roof of mouth
after blisters pop ulcers will form
high fever, difficulty swallowing, drooling and swelling
dehydration can occur
treatment for primary herpetic gingivostomatitis
push fluid intake
analgesia to control pain and fever
bed rest
clean teeth with damp cotton wool
use dilute chlorhexidine to swab gums
aciclovir recommended if very severe or pt is immunocompromised - 200mg tablets 1 tablet five times daily for 5 days
what are the crown prep principles
ideal taper 6 degrees
retentive groove/ slots
bevel functional cusps
two plane buccal reduction
