mock case pres Flashcards
what is a warthin tumour
benign tumour of salivary glands
almost always parotid
aetiology of warthin tumour
exact aetiology unknown
strong association with smoking
also associated with radiation exposure and autoimmune disease
treatment and treatment risks of warthin tumour
surgical excision
risks: scar, paraesthesia, facial nerve weakness and facial nerve paralysis
recurrence and risk of malignancy of a warthin tumour
recurrence is rare
risk of malignancy 0.3%
reversible pulpitis
pain to stimuli which disappears quickly once stimulus removed
particularly responsive to cold and sweet stimuli
aetiologies include exposed dentine, caries and deep restorations
irreversible pulpitis
pain to heat
lingering pain to stimuli
spontaneous pain that may disturb sleep
referred pain
aetiologies include deep caries, deep restorations, fractures exposing pulpal tissues
acute apical abscess
inflammatory reaction to pulpal infection and necrosis
rapid onset, spontaneous pain, TTP, pus, soft tissue swelling
perio-endo lesion/abscess
- symptoms
- swelling site
- periodontal findings
- sensibility testing
- painful, tender when eating, may feel mobile
- attached gingiva usually close to apex
- deep PPD
- negative sensibility tests
step one perio treatment for BPE 4
- radiographic assessment
- full mouth 6PPC
- MPBS
- diagnostic statement
- explain disease, treatments and risk factors
- tailored OHI
- risk factor modification
- supragingival PMPR
why was composite chosen for 15do restoration
moisture control was achieved using dental dam
avoid destructive prep to create self -retentive box
why do smokers gums bleed less
nicotine causes vasoconstriction resulting in less blood flow to gingivae
why was the 14 retained root extracted
unrestorable
infection risk
inadequate OH for overdenture
criteria for engaging perio patient
> =50% improvement in plaque and bleeding
plaque levels <=20% and bleeding levels <=30%
patient met personal targets
why was lithium disilicate chosen for crowns
excellent aesthetics
strong
what cement was used for crowns
dual cure resin cement
what dimensions were the crown preparations
1-1.5mm buccal and labial shoulder
1.5mm incisal reduction
why acrylic for the denture
easier to add to
(abutment teeth likley to be lost in relatively near future)
what does IRMER stand for and who is it in place to protect
ionising radiation medical exposure regulations
in place to protect patients
what are the 3 main aims of IRMER
- minimise unintended, excessive or incorrect exposure
- justify exposures (benefit>risk)
- optimise doses (ALARP)
what does IRR stand for and who is it in place to protect
ionising radiation regulations
in place to protect staff and public
aim of IRR17
minimise radiation exposure to employees and public
principles of cavity prep (3)
no unsupported enamel
no traces of previous restorative material
smooth cavosurface margin angles and line angles
ideal CSMAs for amalgam and composite
amalgam 80-90
composite 90-100
