cardiology Flashcards
condensing osteitis
periapical inflammatory disease that results from a reaction to a dental related infection. This causes more bone production rather than bone destruction in the area (most common site is near the root apices of premolars and molars).
mesial to 37
where is the deep caries
34
alpha fibres
myelinated
sharp pain
stimulated by EPT
C fibres
non myelinated
stimulation
- dull aching pain
- increased pulpal blood flow
- increased pulpal pressure
reversible pulpitis
vital, inflammed pulp
investigations suggest can reverse to health if vital pulp therapy performed
regular response to sensibility tests
- pain to cold - lasts short time
- hydrodynamic expession - microleakage (a-fibres)
- no change to pulp blood flow
NO PAIN AT NIGHT
irreversible pulpitis
spontaenous pain, intermittent, SLEEP DISTURBANCE
negative to cold, pain to hot (e.g. tea/coffee) (C-fibres)
increase in pulpal blood flow
symptomatic periocapical periodontitis
inflammation of the apical periodontium
pain
- biting
- percussion and/or palpation
may have periapical radioluncency
severe pain to percussion and/or palpation highly indicative of degnerating pulp
- RCT required
how to carry out sensibility tests
compare pt response with contralateral healthy tooth
test contralateral healthy tooth first than tooth of concern
- EPT
- thermal - cold or hot
positive response to EPT
- vital pulp tissue in coronal aspect of pulp chamber
- no indication of reversibility of inflammation (healing)
- no correlation between pain threshold and pulp condition (measurement of electric voltage/score is not accurate)
negative response EPT
reliable indicator for pulpectomy procedure in 97.7% cases
treatment of pulp damage options
- indirect pulp cap
- or stepwise excavation or seal caries in
- direct pulp cap
- partial pulp removal - PULPOTOMY
- full pulpal removal - PULPECTOMY
- progress to RCT
stress and dental tx
want to reduce - inflammatory effects (perio)
heart issues (avoid sudden changes in chair positioning to avoid stresses on heart)
extraction affect on SH
any activities which increase blood flow or BP after extraction not recommended
- sports
- manual jobs (day after - inform before tx)
aortic valve disease
valve between left ventricle and aorta doesn’t work properly - can be congenital of from other causes
- aortic valve stenosis - cusps or aortic valve thicken and become stiff which reduced or blocks blood flow from aorta to rest of body
- aortic valve regurgitation - aortic valve doesn’t close properly so blood backflows into left ventricle
congential heart conditions and dental tx
consult with cardiologist over need for antibiotic prophlayxis before carrying out dental tx (higher risk of IE - check where they are in SDCEP)
